Relora® is a unique all natural dietary supplement helps those suffering from stress related irritability, restlessness, food cravings, snacking, weight gain, and poor sleep quality to relax and reclaim a sense of stability and well being without the drowsiness of Kava or the side effects of St. John's Wort: Improves relaxation and sleep Stress-management Weight and appetite control Non-sedating Enhances concentration

The unique, patented botanical extracts in Relora® offer the relaxing qualities of the benzodiazepine class of drugs like Valium™ without negative side effects and validated in anxiolytic animal models. In addition, it normalizes hormone levels associated with stress-induced obesity and poor eating and drinking behaviors. Relora is an exciting new natural anti-anxiety, anti-stress relief formula that helps control stress-related eating and drinking that is non-sedating with potential anti-depressant properties.

Relora® has been shown to reduce Cortisol levels by 37% and increase DHEA levels by 227%. High levels of Cortisol is found to decrease the secretion of the thyroid hormone responsible for regulating metabolism
(article in the June 18, 2002 issue of Woman's World). High cortisol levels cause:

Immunodepression Cholesterol increase Blood pressure increase Loss of sex drive poor sleep weight gain Abdominal fat deposition Tension Hypothyroid Blood sugar elevation Brain and nerve cell destruction Rapid aging

Anxiety is being shown to play a significant role in a wide variety of conditions and disease states. Recent work from the National Institute of Health (NIH) and other major research centers has demonstrated that anxiety is a significant contributor to excess body fat, immune dysfunction, cardiovascular disease and other age-related disorders. Pharmaceutical companies with anxiolytic drugs have launched major consumer advertising campaigns that are fueling the awareness of these problems. Relaxora contains the first natural ingredient to be specifically targeted to anxiety.

Relora® is an all-natural proprietary blend of plant extracts from Magnolia officinalis and Phellodendron amurense that is not habit-forming. Stress has been shown to play a significant role in a wide variety of conditions and disease states. Recent work from the National Institute of Health (NIH) and other major research centers has demonstrates that stress is a significant contributor to excess body fat. This condition is related to stress-induced hormone imbalances, specifically cortisol and DHEA imbalance. Relora can normalize cortisol and DHEA levels in stressed individuals, induce relaxation and act as an aid in controlling weight and stress-related eating and/or drinking. Hormones not only affect emotional well being but also impact appetite and how the body stores and metabolizes fat. Relora enhances mental, emotional and physical vitality which can have a strong positive effect on weight loss efforts. Relora is the perfect adjunct to a planned weight-loss and exercise regimen.

Relora is a natural dietary supplement developed to improve mood, help stressed individuals relax, and to normalize the hormones related to stress-induced eating. 80 percent of stressed adults studied feel more relaxed with Relora. Relora has also been shown in a pilot study to normalize cortisol levels in stressed individuals. Preliminary findings suggest that Relora can decrease the cravings for high fat, high sugar foods in stressed individuals.

Results of Open Human Trial:

• 8 out of 10 people felt more relaxed
• 7 out of 10 people enjoyed more restful sleep
• 9 out of 10 people said it was gentle on the stomach

Stress & Obesity

Chronic stress can cause cravings for cookies, candy, chips and other high-fat, high-carbohydrate foods. The stress-driven appetite for these foods leads to dangerous weight gain, primarily around the waist. Sixty percent (60%) of American adults are overweight or obese, much of which is due to stress-related food cravings. Over twenty percent (20%) of American adults are obese with a stress-related condition known as "metabolic syndrome." This condition is characterized by a “beer belly”, high blood pressure, poor cholesterol readings and high blood sugar.

According to Dr. Pamela Peeke, a former scientist at the National Institutes of Health and associate clinical professor of medicine at the University of Maryland School of Medicine, people with an apple-shaped figure are at greater risk for heart disease, stroke, diabetes, and some types of cancer. "It's not just what you weigh; it's where you weigh it," says Dr. Peeke, author of Fight Fat After Forty (Viking).

Until recently there were few known predictors of stress-induced eating. While most adults who have sugar and/or fat cravings under stress are aware of their out-of-control appetite, scientists have had difficulty in demonstrating actual cause and effect. Dr. Elissa Epel and colleagues at the University of California, San Francisco have now clearly shown that individuals who are high reactors to the stress hormone called cortisol, consume more calories and more sweet foods under stress. Their recent study also demonstrated that greater food consumption occurred in high cortisol reactors when they were in a negative mood.

Relora®, a natural dietary supplement developed by Next Pharmaceuticals, Inc. in Irvine California, was developed to improve mood, help stressed individuals relax, and to normalize the hormones related to stress-induced eating. Eighty percent (80%) of stressed adults studied feel more relaxed with Relora®. Relora® has also been shown in a pilot study to normalize cortisol levels in stressed individuals. Preliminary findings suggest that Relora® can decrease the cravings for high fat, high sugar foods in stressed individuals, most likely due to its ability to normalize stress hormone levels that cause these cravings.

Controlling Weight by Managing Stress

In central nervous system receptor binding assays, the plant extracts in Relora® bind to several important targets associated with anxiety. It does not bind to the benzodiazepine receptors that would cause sedation, yet has the relaxing qualities of the benzodiazepine class of drugs in a validated anxiolytic animal model. In addition, it normalizes hormone levels associated with stress-induced obesity and eating/drinking behavior.
Stress has been shown to play a significant role in a wide variety of conditions and disease states. Recent work from the National Institute of Health (NIH) and other major research centers has demonstrated that stress is a significant contributor to immune dysfunction, cardiovascular disease, other age-related disorders, and to excess body fat. Over twenty percent (20%) of adults have an obesity-like condition characterized by an excessive amount of abdominal fat. This condition is related to stress-induced hormone imbalances, especially imbalances of cortisol and DHEA. Until now, the only course of action for loosing this fat has been stress reduction with exercise and diet. Relora® can normalize cortisol and DHEA levels in stressed individuals, induce relaxation, and act as an aid in controlling weight and stress-related eating or drinking.    

Research finds 8 out of 10 people have better sleep and relaxation with Relora®

In a clinical study conducted at the Living Longer Clinic in Cincinnati, 50 people suffering from chronic stress were administered 200 mg of Relora® three times daily for two weeks. Results showed that 8 out of 10 participants felt more relaxed and 7 out of 10 enjoyed more restful sleep. Post trial analysis revealed 78% of the patients felt more relaxed, and while the product does not cause significant sedation 74% of the patients also experienced a restful night’s sleep. Only 24% of participants reported drowsiness. In addition, Relora® was judged to be gentle on the stomach by 94% of the subjects, and no significant side effects were reported.

Stress and Food Cravings

Chronic stress can cause cravings for cookies, candy, chips and other high-fat, high-carbohydrate foods that may lead to weight gain. While most adults who have sugar and fat cravings under stress are aware of their unhealthy appetite, scientists have had difficulty in demonstrating actual cause and effect. However, Dr. Elissa Epel and colleagues at University of California, San Francisco has shown that individuals who are high reactors to cortisol, consume more calories and more sweet foods under stress. Their recent research also demonstrated that greater food consumption occurred in high cortisol reactors when they were in a negative mood. Elevated levels of cortisol and lowered levels of DHEA are associated with chronic stress. Relora® has been shown to help normalize levels of cortisol and DHEA helping to control stress-related eating and weight gain. A second trial conducted at the Living Longer Clinic measured cortisol and DHEA levels in patients with mild to moderate stress. A two-week regimen of Relora® caused a 227% increase in salivary DHEA and a 37% decrease in salivary cortisol levels, as amounts of each of these substances returned to normal in all subjects during the course of Relora® therapy.

According to Dr. James LaValle, Director of the Living Longer Clinic, "Relora® appears to work with the body's natural chemistry to maintain normal levels of stress hormones. Not only do these stress hormones affect emotional well-being, they have a major impact on appetite and how the body stores and metabolizes fat. By working to re-establish a stable balance of these hormones Relora® appears to help the stress/weight cycles in individuals that eat excessive sweets when under stress."

How does it work?

Relora® was designed and evaluated to help control stress-related symptoms such as irritability, emotional ups and downs, restlessness, tense muscles, poor sleep, and concentration difficulties. It uses an advanced combination of magnolia and phellodendron extracts to help normalize levels of the cortisol and DHEA hormones in the body to promote the management of stress related symptoms. Relora® works by binding to stress receptors in the nervous system to promote relaxation and feelings of well being while ignoring receptors associated with sedation.

Animal Model

The plant extracts in Relora have been shown to be an effective non-sedating anti-stress product in an animal model known as the "Chick Social Separation-Stress Procedure." The excellent results of the patent-pending extracts in Relora using this model were published in Psychopharmacology (2001) 153:219-234.

Safety Studies An extensive literature review of the chemical constituents along with the parent plants' use for hundreds of years indicates that this material is safe for its intended use. An acute toxicity study in rats (5g/kg) with 14-day observation revealed no untoward effects of the individual extracts or the combination in Relora except mild diarrhea and slight sedation in female rats. No side effects are expected at the recommended human dosage.

Human Trials

The first formulation of Relora® was tested and found to be a safe, effective, rapid acting, non-sedating dietary supplement that helps control occasional mild anxiety. Fifty (50) subjects were treated with Relora® for two weeks. The recommended dosage was 200mg of Relora®three times daily. (The new and improved Relora dosage is 250mg three times daily.) Based on pre-clinical studies, Relora® was designed and evaluated against the following concepts: Relora® helps control occasional mild anxiety or mild depression and the associated symptoms including irritability, emotional ups and downs, restlessness, tense muscles, poor sleep and concentration difficulties.

Post-trial analysis revealed an excellent agreement (82%) with the pretrial concept. Relaxation was reported by 78% of the patients. Though the product does not cause significant sedation, 74% of the patients had a restful sleep. No significant side effects were reported. When subjects were asked about drowsiness, only 24% reported that they were drowsy. Relora® was judged to be gentle on the stomach by 94% of the subjects. A second trial was undertaken to measure cortisol and DHEA levels in patients with mild to moderate stress. Elevated cortisol levels and depressed DHEA levels are associated with chronic stress. A two-week regimen of Relora® caused a significant (P = 0.003) increase in salivary DHEA (227%) and a significant (P = 0.01) decrease in morning salivary cortisol levels (37%). These significant findings support Relora’s ability to relieve stress and its potential role in weight control and stress-related eating and drinking behavior.

There are many possible considerations for use of Relora®:

• Body fat close to 20% or more of total body mass (BMI)
• Over weight by at least 10 pounds
• Abdominal weight loss
• Diabetes or history of diabetes in the family
• Blood pressure close to 140 or higher
• Above average abdominal body fat
• Above normal stress and anxiety
• Difficulty sleeping
• Desire to find an alternative or complement prescription drugs
• Smoker

Botany

Magnolia is named for the French pharmacognocist, Pierre Magnol, M.D. (1638-1715), son of an apothecary and whose mother came from a family of physicians. Magnol was a graduate of the Medical College of Montpellier (1659), recipient of the honorary title brevet de medecin royal given by the King of France (1663), Catholic convert from Calvinism (1685), demonstrator of botany (1687), royal professor of medicine: brevet de professeur royal (1694), director of the botanical garden with lettres de noblesse (1697), a founding member of the Société Royale des Sciences de Montpellier (1706), and was appointed to the Académie Royale des Sciences in Paris (1709). Magnol's brilliant work, in which he frequently added notes on the medicinal and other uses of plants to his organized tables of plant classification, later inspired the founder of the current scientific Linnaean taxonomy (plant classification system), the eighteenth-century botanist, Carl von Linne (in Latin: Carolus Linnaeus).

Linnaeus was the son of an avid gardener and a Lutheran pastor in Sweden. His family hoped he would become a priest, but he went to the University of Lund in 1727 to study medicine, transferred to the University of Uppsala and completed his medical degree at the University of Harderwijk in the Netherlands in 1735. Training in botany was part of the medical curriculum, for every doctor had to prepare and prescribe drugs derived from medicinal plants. He practiced medicine in Sweden and was awarded a professorship at Uppsala in 1741. His most famous student, Daniel Solander, was the naturalist on Captain James Cook's first round-the-world voyage, and brought back the first plant collections from Hawaii, Australia and the South Pacific to Europe.

Linnaeus' faith was natural theology, a school of thought established by Saint Thomas Aquinas. Since God created the world, we can see God's wisdom by studying His creation. Natural theology is the science of God, so far as God can be known by the light of reason. It is the science that God extended through self revelation. Linnaeus wrote in the preface to a late edition of Systema Naturae: "Creationis telluris est gloria Dei ex opere Naturae per Hominem solum": "The Earth's creation is the glory of God, as seen from the works of Nature by Man alone." The naturalist's task was to construct a natural classification that reveals the Divine Order of the universe.

However, Linnaeus's plant taxonomy was based solely on the number and arrangement of the reproductive organs; a plant's class was determined by its stamens (male organs), and its order by its pistils (female organs). This resulted in unnatural groupings. "Plants" without obvious sex organs were classified in the Class Cryptogamia, or "plants with a hidden marriage," which lumped together the algae, lichens, fungi, mosses and other bryophytes, and ferns. Linnaeus admitted that this was an "artificial classification," not a natural one, which would take into account all the similarities and differences between organisms. But like many naturalists of the time, in particular Erasmus Darwin, Linnaeus attached great significance to plant sexual reproduction, which had only recently been rediscovered. Linnaeus wrote in 1729: "The flowers' leaves. . . serve as bridal beds which the Creator has so gloriously arranged, adorned with such noble bed curtains, and perfumed with so many soft scents that the bridegroom with his bride might there celebrate their nuptials with so much the greater solemnity. . ."

The sexual basis of Linnaeus's plant classification was controversial and failed in many cases. Later systems of classification largely follow John Ray's practice of using morphological evidence from all parts of the organism in all stages of its development. What survived of the Linnean system is its method of hierarchical classification and custom of binomial nomenclature.

Since Aristotle, biologists used the word genus for a group of similar organisms, and then sought to define the differentio specifica: the specific difference of each type of organism. Linnaeus' innovation was the grouping of genera into higher taxa that were also based on shared similarities with genera grouped into orders, orders into classes, and classes into kingdoms. Later biologists added additional ranks between these to express additional levels of similarity.

Before Linnaeus, species naming practices varied. For instance, the common wild briar rose was referred to by some botanists as Rosa sylvestris inodora seu canina and by others as Rosa sylvestris alba cum rubore, folio glabro. With great numbers of plants and animals being brought to Europe from Asia, Africa, and the Americas, Linnaeus simplified naming by designating one Latin name for the genus, and one for the species. Thus in his two-volume work Species Plantarum (The Species of Plants), Linnaeus renames the briar rose with the still-used binomial ("two names") species name: Rosa canina. The oldest plant names accepted as valid today are those published in Species Plantarum in 1753, while the oldest animal names are those in the tenth edition of Systema Naturae (1758), the first edition to use the binomial system throughout. Although Linnaeus was not the first to use binomials, he was the first to use them consistently.

Linnaeus's hierarchical classification and binomial nomenclature, much modified, have remained standard for over 200 years. His writings have been studied succeeding generations of naturalists, including Erasmus Darwin and Charles Darwin.

Claims

What is claimed is:

Description [0001] This application claims the benefit of U.S. Provisional Application No. 60/255,402 filed Dec. 15, 2000, which is incorporated by reference herein in its entirety.

1. INTRODUCTION

[0002] The present invention relates to novel methods and compositions for the treatment, prevention, or management of sleeplessness, restlessness and weight gain. The methods and compositions utilize plants, portions thereof or extracts therefrom belonging to the Magnoliaceae family. In addition, the methods and compositions utilize mixtures of specific small molecules extracted from the plants belonging to the family Magnoliaceae, such as, but not limited to, magnolol, honokiol, and magnoflorine. The unique compositions of the invention may also comprise various amounts of the Magnoliaceae plant, plant extract, plant extracts combined with different amounts of biologically active small molecules or other therapeutic agents. These compositions are particularly useful for the treatment of sleeplessness, restlessness and weight gain in humans. The invention also encompasses various modes of administration of the therapeutic extracts or other compositions of the invention.

2. BACKGROUND OF THE INVENTION

[0003] The recent growth in sales of natural products labeled as dietary supplements in the United States has renewed scientific interest in the study of the prophylactic and therapeutic effects of multi-component botanical products. Unlike single entity pharmaceutical products, botanical products comprise a large number of diverse chemical constituents that often act synergistically to exert a desired biological effect. The type of extraction process utilized and the manner in which the formulation is standardized have dramatic effects on the pharmacological activity of the final product. The development of new botanical products requires multidisciplinary effort consisting of expertise in ethnobotany, natural product chemistry, analytical chemistry, pharmacology, and natural product extraction.
[0004] 2.1 Sleeplessness, Restlessness and Weight Control
[0005] Sleep is necessary for survival and good health, but why sleep is needed or exactly how it benefits people is not fully understood. Individual requirements for sleep vary widely; healthy adults may need as few as 4 hours or as many as 9 hours of sleep every day. Most people sleep at night, but many must sleep during the day to accommodate work schedules. This situation often leads to sleep disorders. Most sleep disorders are common.
[0006] How long a person sleeps and how rested a person feels on waking can be influenced by may factors, including excitement or emotional distress. Medications also can play a part; some medications make a person sleepy while other makes sleeping difficult. Even some food elements of additives such as caffeine, strong spices, and monosodium glutamate (MSG) may affect sleep.
[0007] Sleep is not a uniform state; it has several distinct stages through which it normally cycles five or six times every night. Sleep progresses from stage 1 (the lightest level, during which the sleeper can be awakened easily) to stage 4 (the deepest level, during which waking the sleeper is difficult). In stage 4, the muscles are relaxed, the blood pressure is at the lowest, and the heart and breathing rates are at their slowest. Besides these four stages, there is a form of sleep accompanied by rapid eye movements (REM) and behavioral activity. During REM sleep, electrical activity in the brain is unusually high, somewhat resembling that of wakefulness. The eye movement and brain wave changes that accompany REM sleep can be recorded electrically on an electroencephalogram (EEG).
[0008] In REM sleep, the rate and depth of breathing increase, but the muscles are greatly relaxed more so than during the deepest levels of non-REM sleep. Most dreaming occurs during REM and stage 3 sleep, while most talking during sleep, night terrors, and sleepwalking occur during stages 3 and 4. During a normal night's sleep, REM sleep immediately follows each of the five or six cycles of four-stage non-REM sleep, but it can occur at any of the stages.
[0009] If emotional stress is causing the sleep disorder, treatment to relieve the stress is more useful than taking sleep medication. When the sleep disorder is cause by depression, the depression should be thoroughly evaluated and treated by a doctor. Some antidepressant drugs can improve sleep because they have sedating properties. When sleep disorders interfere with a person's normal activities and sense of well-being, the intermittent use of sleep medications (sedatives, hypnotics) may be useful.
[0010] A sedative drug decreases activity, moderates excitement, and calms the recipient, whereas a hypnotic drug produces drowsiness and facilitates the onset and maintenance of a state of sleep that resembles natural sleep in its electroencephalographic characteristics and from which the recipient can be aroused easily. The latter effect sometimes is called hypnosis.
[0011] Nonbenozodiazepine sedative-hypnotic drugs belong to a group of agents that depress the central nervous system (CNS) in a relative nonselective, dose-dependent fashion, producing progressively calming or drowsiness (sedation), sleep (pharmacological hypnosis), unconsciousness, coma, surgical anesthesia, and fatal depression of respiration and cardiovascular regulation.
[0012] Hypnotics (sedatives, minor tranquilizers, anti-anxiety drugs) are among the most commonly used drugs. Most are quite safe, but all can lose their effectiveness once a person becomes accustomed to them. An undesirable side effect of hypnotics, however, are the withdrawal symptoms when use is discontinued. After more than a few days' use, discontinuing a hypnotic can make the original sleep problem worse (rebound insomnia) and increase anxiety. Also most hypnotics require a doctor's prescription because they may be habit-forming or addictive, and overdose is possible. Hypnotics are particularly risky for the elderly and for people with breathing problems because they tend to suppress brain areas that control breathing. They also reduce daytime alertness, making driving or operating machinery hazardous. Hypnotics are especially dangerous when taken with alcohol, other hypnotics, narcotics, antihistamines, and anti-depressants. All of these drugs cause drowsiness and can suppress breathing, making the combined effects more dangerous.
[0013] Stress plays a major role in weight management. Stress activates the hypothalamic/pituitary/adrenal axis resulting in an increase in cortisol levels. Cortisol increases the availability of glucose through hepatic gluconeogeneses and the release of glucose substrates from fat cells and muscles. The uptake of glucose is inhibited, resulting in hyperglycemia and hyperlipidemia. The increase in cortisol levels signals the brain that the body is in stress causing food cravings, especially high fat, high sugar foods. These foods, in turn, cause additional stress thereby fueling the stress-cortisol cycle. Eventually, more fat is stored than the body needs unless sufficient exercise is in place to compensate, or the stress is reduced. Central nervous stimulants have been used to suppress appetite in an attempt to counteract stress-induced appetite. This approach not only aggravates the problem due to a direct CNS stimulation effect, but also has a high abuse potential and several serious side effects including cardiovascular and cerebral vascular effects. Ephedra, which is also known as ma huang, is a dietary supplement that is used for weight control and is an example of this type of approach. The purported mechanism of action for Ephedra is CNS stimulation due to the presence of ephedrine alkaloids in the extract.
[0014] 2.3 Magnoliaceae Plant Extracts
[0015] Extracts from plants belonging to the family Magnoliaceae have been and may still be used in Chinese herbalism. The bark of Magnolia officinalis Rehder et Wilson, "Hou-po" in Chinese, has been used in Chinese traditional medicine. (Watanabe, K.; Watanabe, H. Y.; Goto, Y.; Yamamoto, N.; Yoshizaki, M.; "Studies on the Active Principles of Magnolia Bark. Centrally acting Muscle Relaxant Activity of Magnolol and Honokiol," Japan. J. Pharmacol. 25, 605 (1975)). Magnolol is the bioactive constituent of Magnolia Cortex, the bark of Magnolia officinalis, Rehd. Et Wils., Magnoliaceae or of M. obvata, Thunb., called wakoboku in Japanese medicine. Honokiol is the bioactive principle isolated from the bark of Magnolia obovata, Thunb., Magnoliaceae and other Magnolia species used in Japanese and Chinese traditional medicine.
[0016] The bark of Magnolia officinalis, is reportedly used as an antibacterial, antiseptic, antispasmodic, aphrodisiac, appetizer, digestive, diuretic, emmenagogue, expectorant, ophthalmic, stomachic, and tonic. (Chevalier, A., The Encyclopedia of Medicinal Plants, Dorling Kindersley, London, 1995).
[0017] The ether extract of magnolia bark showed a central depressant effect and centrally acting muscle relaxation effect. (Watanabe et al.) Muscle relaxation was shown to be dose-dependent, wherein minimum effective doses required at least 90-100 mg/kg, while sedative symptoms were observed at lower doses. At large doses, honokiol showed a muscle relaxing effect for 3 hours (250 mg/kg) and produced a loss of righting reflex (500 mg/kg). (Watanabe et al. p. 606).
[0018] In mice, magnolol produced hypomotility, ptosis, and sedation at 63 mg/kg when administered intraperitoneally. (Watanabe, K.; Watanabe, H.; Goto, Y.; Yamaguchi, M.; Yamamoto, N.; Hagino, K., "Pharmacological Properties of Magnolol and Honokiol Extracted from Magnolia officinalis: Central Depressant Effects," Journal of Medicinal Plant Research: Planta Medica, 49, pp. 130-108, (1983)). At a dose of 125 mg/kg magnolol induced sedation, ataxia, and prominent muscle relaxation for 2 hr after injection. Magnolol at a dose of 250 mg/kg produced an ataxia within 10 min, loss of righting reflex in 40 min, and muscle relaxation over 3 hr. Honokiol produced similar effects at doses of 125, 250, and 500 mg/kg i.p. Id.
[0019] To date, there are a number of sleep disorders for which there is no dietary supplement available to either prevent or alleviate the disorder or symptoms associated therewith. It is desirable to discover and develop dietary supplements or pharmaceutical compositions based upon natural materials that are both safe and effective. It is particularly desirable to develop plant extracts for the prevention, treatment, or control of sleeplessness, restlessness and weight gain do to stress or lack of sleep.

In a preferred embodiment, the mammal is human and the extracts comprise at least two compounds selected from the group consisting of magnolol, honokiol, and magnoflorine. In a more preferred embodiment, the extracts comprise at least 2% honokiol by weight of the composition and preferably, 2% honokiol by weight of the composition. In a most preferred embodiment the extracts are aqueous or lower alcohol aqueous extracts.
[0037] The invention further encompasses compositions for preventing, treating, and managing sleeplessness, restlessness, or weight gain including, but not limited to, weight gain due to lack of sleep comprising a therapeutically effective amount of Magnoliaceae plant or an extract thereof including, but not limited to, magnolol, honokiol and magnoflorine.
[0038] In one embodiment of the invention, the composition for preventing sleeplessness comprises Magnoliaceae plant or extracts thereof in an amount sufficient to prevent the onset of sleeplessness or sleeplessness related symptoms. In another embodiment of the invention, for mammals already suffering from sleeplessness, the invention is directed to compositions and administered dosages comprising Magnoliaceae plant in sufficient amount to reduce sleeplessness or the symptoms associated with sleeplessness. In yet another embodiment of the invention, for mammals already suffering from sleeplessness, the invention is directed to a method for treating sleeplessness by . administering compositions comprising Magnoliaceae plant extract in a therapeutically sufficient amount to treat sleeplessness.
[0039] In another embodiment of the invention, the composition for reducing or preventing restlessness comprises Magnoliaceae plant or extracts thereof in an amount sufficient to prevent the onset of restlessness or restlessness related symptoms. In another embodiment of the invention, the composition for treating restlessness is in sufficient amount and regularly administered dosage to reduce or eliminate restlessness related symptoms in mammals suffering from restlessness. In yet another embodiment of the invention, for mammals already suffering from restlessness, the invention is directed to a method for treating restlessness by administering compositions containing Magnoliaceae plant extract in a therapeutically sufficient amount to either prevent or treat restlessness.
[0040] In yet another embodiment, the invention encompasses compositions, including pharmaceutical compositions or dietary supplements, to be used in managing weight gain including, but not limited to, weight gain due to stress or lack of sleep. Further, the invention encompasses methods for managing weight gain in a mammal which comprises administering a magnoliaceae plant or extract thereof to a mammal in need thereof.
[0041] In another embodiment, the invention encompasses methods for managing weight gain in a human, particularly wherein said human is an obese male or an obese female.
[0042] In a further embodiment, the invention encompasses methods for managing weight gain in a human, particularly wherein said human is a male or a female of average weight.
[0043] In still another embodiment, the invention encompasses methods for managing weight gain in a human, particularly wherein said human is not concurrently using; has not previously used another dietary supplement or pharmaceutical composition for weight control; or both. The extracts of the invention are particularly useful for humans taking prescription medications for weight gain including, but not limited to, weight gain due to stress or lack of sleep. The invention, however, encompasses the use of the extracts in humans before, during, and after treatment with prescription therapies.
[0044] More preferably, the Magnoliaceae plant extract is obtained by extracting Magnoliaceae plant parts with a lower alcohol, water, or mixtures thereof. In another preferred embodiment of the invention, the compositions comprise a Magnoliaceae plant or an extract thereof and an additional amount of magnolol, honokiol, or magnoflorine in excess to any amount that may be present in the Magnoliaceae plant extract.
[0045] The invention encompasses compositions which comprise magnolol, honokiol, magnoflorine, or pharmaceutically acceptable salts thereof and pharmaceutically acceptable excipients, carriers, or diluents. Further, such magnolol, honokiol, magnoflorine compositions can comprise non-sedating sleep aids or other therapeutic agents. The compositions comprise magnolol, honokiol, magnoflorine, or a mixture thereof in an amount sufficient and regularly administered dosage to prevent, treat, or manage sleeplessness, restlessness, weight gain due to stress or lack of sleep, or all three.
[0046] The disclosure is based, in part, on the discovery that Magnoliaceae plant or extracts thereof, alone or in combination with other sleep aids, induces relaxation without loss of motor function and restful sleep. Without being limited by theory, it is believed that Magnoliaceae plant extracts act synergistically or at least more than additively by binding to one or more receptor sites to collectively diminish the symptoms of sleeplessness or restlessness without causing a sedative or addictive effect.
[0047] In a preferred embodiment, the invention encompasses compositions, and the use thereof, which comprises a water-soluble extract of a Magnoliaceae plant. In a most preferred embodiment, such extracts are produced by extraction with an aqueous alcohol solvent system such that the extracts preferably comprise one or more of the following small organic compounds which naturally occur in the plants: magnolol, honokiol, magnoflorine, and the like. It has been discovered that such extracts have a unique receptor binding affinities despite the fact that the extracts are mixtures of components. Thus, the extracts of the invention have unique benefits in preventing, treating, or managing disorders. Moreover, the preferred extracts of the invention are useful for treating and preventing sleeplessness, restlessness, weight gain due to stress or lack of sleep, or all three without a sedative or addictive effect. Similarly, the extracts of the invention reduce or avoid adverse effects associated with certain CNS drugs such as physical dependency, withdrawal problems, impaired coordination, loss or reduction of motor function, slowed reaction time, sedation, weight gain, constipation, dry mouth, confusion, blurred vision, nausea, diarrhea, or headaches.
[0048] The extracts of the invention are particularly useful for humans taking prescription medications for sleeplessness, restlessness, or both. The invention, however, encompasses the use of the extracts in humans before, during, and after treatment with prescription or conventional therapies.
[0049] In accordance with the present invention, the Magnoliaceae plant can be used alone or in combination with other known therapeutic agents or techniques to reduce sleeplessness, restlessness, weight gain due to stress or lack of sleep, or all three. Such agents may include vitamins and minerals, such as magnesium, calcium, or non-sedating sleep aids.
[0050] Since novel formulations of Magnoliaceae plant are disclosed herein, the invention also encompasses methods of using the novel formulations for the treatment of sleeplessness, restlessness, weight gain due to stress or lack of sleep, or all three in a mammal, wherein the mammal is preferably a human.
[0051] 4.1 Method for Obtaining Magnoliaceae Plant Extracts
[0052] The plants belonging to the "Magnoliaceae family" used in the present invention are plants belonging to the genus Liriodendron and Magnolia. Species belonging to the Liriodendron genus include, but are not limited to, Liriodendron tulipifera and Liriodendron chinense. Species belonging to the Magnolia genus include, but are not limited to, Magnolia acuminata, Magnolia ashei, Magnolia biodii, Magnolia cylindrica, Magnolia cambellii, Magnolia denudata, Magnolia fraseri, Magnolia grandiflora, Magnolia hypoleuca, Magnolia kobus, Magnolia liliiflora, Magnolia loegneri, Magnolia macrophylla, Magnolia officinalis, Magnolia pyramidata, Magnolia sargentiana, Magnolia seiboldii, Magnolia soulangiana, Magnolia sprengeri, Magnolia stellata, Magnolia tripetala, Magnolia virginiana, Magnolia zenii, and Michelia figo. The most preferable plants are Magnolia officinalis and its variants.
[0053] The Magnoliaceae plant includes the plant parts as defined above, optionally the plant parts may be cut into small pieces or ground into a powder. Preferably, the plant part includes an extract of the Magnoliaceae plant. During a typical extraction process, the Magnoliaceae plant body, preferably cut into small pieces or ground into a powder, is placed in a Soxhlet extractor and extracted with any suitable solvent. Typical solvents include, but are not limited to, water, lower alcohols, or mixtures thereof. Preferably, the solvents used in the extraction include water, ethanol, and mixtures thereof. The solvent is maintained at reflux and the Magnoliaceae plant body is extracted for about 8 hours to about 48 hours. Preferably, the Magnoliaceae plant is extracted for about 12 hours to about 40 hours, and more preferably for about 18 hours to about 30 hours.
[0054] Subsequently, the solvent is separated and reduced in volume. Optionally, the solvent may be extracted with a second solvent. Thereafter, the extraction solvents are collected and reduced in volume either under low pressure or by evaporation to form a residue. Optionally, the residue is diluted and purified by gravity chromatography using at least one suitable solvent easily determined by a skilled artisan with little or no experimentation as the mobile phase. Optionally, the ratio of solvents within the solvent mixture may be gradually changed.
[0055] An alternative extraction process comprises adding a suitable solvent to the Magnoliaceae plant body, either grounded into a powder or cut into pieces. The solvents include, but are not limited to water, a lower alcohol, and mixtures thereof. Preferably, the solvents are water, ethanol, or mixtures thereof. The mixture of Magnoliaceae plant and solvent is allowed to sit overnight, preferably for about 6 hours to about 40 hours, preferably for about 8 hours to about 18 hours. Subsequently, the mixture is filtered, separating the solids from the filtrate. The solids are mixed with more solvent and allowed to sit overnight, preferably for about 6 hours to about 40 hours, preferably from about 12 hours to 32 hours, and more preferably from about 8 hours to about 18 hours. The mixture is separated a second time by filtration and the filtrates from both extractions are combined, and concentrated under reduced pressure to obtain a residue. The residue is vacuum dried for about 1 to about 10 hours, preferably for about 1 to about 2 hours at room temperature.
[0056] Yet another alternative extraction process comprises combining a suitable solvent to the Magnoliaceae plant body, either grounded into a powder or cut into pieces, in a ratio of about 4:1 to about 7:1 by volume to form a mixture. The mixture is heated to a temperature of about 1.degree. F. below the boiling point of the solvent and stirred for about an hour. Preferably, if water is used as a solvent, the temperature is about 212.degree. F. The mixture is filtered and the filtrate is washed with fresh solvent in a volume ratio of about 1:1. Subsequently the filtrate is concentrated under reduced volume and dried in a vacuum oven. In this method, suitable solvents include ethanol, methanol, chlorinated solvents, propanol, 2-propanol, water, denatured industrial grade alcohol such as SDA-35, and mixtures thereof. Preferably, suitable solvents include water, ethanol, SDA-35, and mixtures thereof.
[0057] 4.2 Compositions Comprising Magnoliaceae Plant Extracts and Modes of Administration
[0058] The invention comprises compositions of Magnoliaceae plant or plant extracts with physiologically suitable carriers including, but not limited to, pharmaceutical carriers for the treatment of sleeplessness, restlessness, weight gain including, but not limited to, weight gain due to stress or lack of sleep, or all three. In a preferred embodiment, the compositions of the present invention comprise at least two compounds selected from the group consisting of magnolol, honokiol, and magnoflorine. More preferably, the compositions include at least 2% honokiol by weight of the composition; preferably including 2% honokiol by weight of the composition. Most preferably, the compositions are obtained from the extraction of Magnoliaceae plant parts with an aqueous organic solution mixture, in particular a water and ethanol solution mixture, comprising small molecule compounds.
[0059] The magnitude of the therapeutic dose of an active ingredient in the acute or chronic management of a disorder or condition will vary with the severity of the disorder or condition to be treated and the route of administration. The dose, and perhaps the dose frequency, will also vary according to age, body weight, response, and the past medical history of the consumer or patient. Suitable dosing regimens can be readily selected by those skilled in the art with due consideration of such factors.
[0060] In one embodiment of the present invention, Magnoliaceae plant comprises about 2% to about 100% by weight of the composition. In a preferred embodiment, Magnoliaceae plant comprises about 5% to about 95% by weight of the composition. In a more preferred embodiment, Magnoliaceae plant comprises about 10% to about 90% by weight of the composition.
[0061] In another embodiment of the present invention using Magnoliaceae plant extracts, Magnoliaceae plant extracts comprise about 25% to about 100% by weight of the composition. In a preferred embodiment, Magnoliaceae plant extracts comprise about 35% to about 90% by weight of the composition. In a more preferred embodiment, Magnoliaceae plant extracts comprise about 40% to about 80% by weight of the composition.
[0062] In an embodiment, the composition of the invention comprises Magnoliaceae plant or plant extract present in an amount of about 35% to about 90% by weight and at least one non-sedating sleep aid. Alternatively, the compositions of the invention can be administered sequentially or simultaneously in combination with at least one non-sedating sleep aid.
[0063] Magnoliaceae plant or extracts thereof can be formulated using standard formulation techniques into gel caps, teas, tablets, etc. See, e.g., Remington's Pharmaceutical Sciences, 18th ed., Mack Publishing, Easton Pa. (1990). Magnoliaceae plant extracts of the invention may be formulated into a dietary supplement or a pharmaceutical preparation for the administration to mammals for the treatment of sleeplessness, restlessness, weight gain, preferably weight gain due to stress or lack of sleep, or all three. In a preferred embodiment, the mammal is human.
[0064] Compositions comprising Magnoliaceae plant extracts of the invention formulated in a compatible pharmaceutical carrier may be prepared, packaged, and labeled for treatment, prevention, or management of sleeplessness, restlessness, or symptoms thereof.
[0065] If the composition is water-soluble, then it may be formulated in an appropriate buffer, for example, phosphate buffered saline or other physiologically compatible solutions. Alternatively, if the resulting composition has poor solubility in aqueous solvents, then it may be formulated with a non-ionic surfactant such as Tween or polyethylene glycol. Thus, the compositions and their physiologically acceptable solvates may be formulated for administration by inhalation or insufflation (either through the mouth or the nose), oral, buccal, parenteral, or rectal administration.
[0066] For oral administration, the pharmaceutical preparation may be in liquid form, for example, solutions, syrups or suspensions, or may be presented as a drug product for reconstitution with water or other suitable vehicle before use. Such liquid preparations may be prepared by conventional means with pharmaceutically acceptable additives such as suspending agents (e.g., sorbitol syrup, cellulose derivatives or hydrogenated edible fats); emulsifying agents (e.g., lecithin or acacia); non-aqueous vehicles (e.g., almond oil, oily esters, or fractionated vegetable oils); and preservatives (e.g., methyl or propyl-p-hydroxybenzoates or sorbic acid). The pharmaceutical compositions may take the form of, for example, tablets or capsules prepared by conventional means with pharmaceutically acceptable excipients such as binding agents (e.g., pregelatinized maize starch, polyvinyl pyrrolidone or hydroxypropyl methylcellulose); fillers (e.g., lactose, microcrystalline cellulose or calcium hydrogen phosphate); lubricants (e.g., magnesium stearate, talc or silica); disintegrants (e.g., potato starch or sodium starch glycolate); or wetting agents (e.g., sodium lauryl sulphate). The tablets may be coated by methods well-known in the art. In a preferred embodiment, the pharmaceutical composition may take the form of a capsule or powder to be dissolved in a liquid for oral consumption. Preparations for oral administration may be suitably formulated to give controlled release of the active compound.
[0067] For buccal administration, the compositions may take the form of tablets or lozenges formulated in conventional manner.
[0068] The compounds may be formulated for parenteral administration by injection, e.g., by bolus injection or continuous infusion. Formulations for injection may be presented in unit dosage form, e.g., in ampules or in multi-dose containers, with an added preservative. The compositions may take such forms as suspensions, solutions or emulsions in oily or aqueous vehicles, and may comprise formulatory agents such as suspending, stabilizing and/or dispersing agents. Alternatively, the active ingredient may be in powder form for constitution with a suitable vehicle, e.g., sterile pyrogen-free water, before use.
[0069] The compounds may also be formulated in rectal compositions such as suppositories or retention enemas, e.g., comprising conventional suppository bases such as cocoa butter or other glycerides.
[0070] In addition to the formulations described previously, the compounds may also be a formulated as a sustained and/or timed release formulation. The compositions must be maintained above some minimum therapeutic dose to be effective. Such sustained and/or timed release formulations may be administered by implantation (for example, subcutaneously or intramuscularly) or by intramuscular injection. Thus, for example, the compounds may be formulated with suitable polymeric or hydrophobic materials (for example, as an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble derivatives, for example, as a sparingly soluble salt. Liposomes and emulsions are well known examples of delivery vehicles or carriers for hydrophilic drugs. Common timed and/or controlled release delivery systems include, but are not be restricted to, starches, osmotic pumps, or gelatin micro capsules.
[0071] The compositions may, if desired, be presented in a pack or dispenser device which may comprise one or more unit dosage forms comprising the active ingredient. The pack may for example comprise metal or plastic foil, such as a blister pack. The pack or dispenser device may be accompanied by instructions for administration.
[0072] 4.3 Dietary Supplements Comprising Magnoliaceae Plant Extract
[0073] The compositions of the invention may include food compositions, beverage compositions, over the counter, and dietary supplements. The Magnoliaceae plant or plant extract may be added to various foods so as to be consumed simultaneously. Preferably, the Magnoliaceae plant extract comprises at least two compounds selected from the group consisting of magnolol, honokiol, and magnoflorine. More preferably, the Magnoliaceae plant extract comprises about 2% honokiol by weight of the composition. As a food additive, the Magnoliaceae plant or plant extracts of the invention may be used in the same manner as conventional food additives, and thus, only needs to be mixed with other components to enhance the taste. Taste enhancement includes, but is not limited to, imparting to food a refreshingness, vitality, cleanness, fineness, or bracingness to the inherent taste of the food.
[0074] It will be recognized that dietary supplements may not use the same formulation ingredients or have the same sterile and other FDA requirements as pharmaceutical compositions. The dietary supplements may be in liquid form, for example, solutions, syrups or suspensions, or may be in the form of a product for reconstitution with water or any other suitable liquid before use. Such liquid preparations may be prepared by conventional means such as a tea, health beverage, dietary shake, liquid concentrate, or liquid soluble tablet, capsule, pill, or powder such that the beverage may be prepared by dissolving the liquid soluble tablet, capsule, pill, or powder within a liquid and consuming the resulting beverage. Alternatively, the dietary supplements may take the form of tablets or capsules prepared by conventional means and optionally including other dietary supplements including vitamins, minerals, other herbal supplements, binding agents, fillers, lubricants, disintegrants, or wetting agents, as those discussed above. The tablets may be coated by methods well-known in the art. In a preferred embodiment, the dietary supplement may take the form of a capsule or powder to be dissolved in a liquid for oral consumption.
[0075] The magnitude of the dietary dose of an active ingredient in the acute or chronic management of a disorder or condition will vary with the severity of the disorder or condition to be treated and the route of administration. The dose, and perhaps the dose frequency, will also vary according to age, body weight, response, and the past medical history of the consumer or patient. Suitable dosing regimens can be readily selected by those skilled in the art with due consideration of such factors.
[0076] The amount of Magnoliaceae plant or plant extract in a beverage or incorporated into a food product will depend on the kind of beverage, food and the desired effect. In general, a single serving comprises an amount of about 0.1% to about 50%, preferably of about 0.5% to about 20% of the food composition. More preferably a food product comprises Magnoliaceae plant or plant extract in an amount of about 1% to about 10% by weight of the food composition.
[0077] Examples of food include, but are not limited to, confectionery such as sweets (candies, jellies, jams, etc.), gums, bean pastes, baked confectioneries or molded confectioneries (cookies, biscuits, etc.), steamed confectioneries, cacao or cacao products (chocolates and cocoa), frozen confectioneries (ice cream, ices, etc.), beverages (fruit juice, soft drinks, carbonated beverages), health drinks, health bars, and tea (green tea, black tea, etc.).
[0078] 4.4 Dosage
[0079] The magnitude of a therapeutic or prophylactic dose of Magnoliaceae plant in the prevention, treatment, or management of sleeplessness, restlessness, weight gain including, but not limited to, weight gain due to stress or lack of sleep, or all three will vary with the severity of the condition of the consumer or patient to be treated and the route of administration. The dose, and dose frequency, will also vary according to the age, body weight, condition and response of the individual consumer or patient, and the particular Magnoliaceae plant combination used. All combinations described in the specification are encompassed as therapeutic, and it is understood that one of skill in the art would be able to determine a proper dosage of particular Magnoliaceae plant composition using the parameters provided in the invention.
[0080] In general, the total daily dose ranges of the Magnoliaceae plant for the conditions described herein are generally from about 1mg/kg to about 140mg/kg administered in divided doses administered parenterally, orally, or topically. A preferred total daily dose is from about 7 mg/kg to about 100 mg/kg of the Magnoliaceae plant composition. When a Magnoliaceae plant extract is used, the total daily dose ranges of the Magnoliaceae plant extract for the conditions described herein are generally from about 4 mg/kg to about 12.5 mg/kg administered in divided doses administered parenterally, orally, or topically. A preferred total daily dose is from about 5 mg/kg to about 11 mg/kg of the Magnoliaceae plant extracts.
[0081] Alternatively, the daily dose of the Magnoliaceae plant for the conditions described herein are generally from about 100 mg to about 800 mg, preferably from about 200 mg to 600 mg, of a 2% honokiol composition.
[0082] For example, in one embodiment, the daily dose ranges of Magnoliaceae plant extracts compositions described herein are generally about 7 mg per kg body weight of Magnoliaceae plant extracts composition. Preferably the Magnoliaceae plant extracts formulation of the invention is given daily until the symptoms cease, followed by two to ten additional cycles, each lasting about 60 days in duration. When the dose is administered orally, a sustained release formulation can be used so that a fairly constant level of Magnoliaceae plant extracts is provided over the course of treatment. As the Magnoliaceae plant extracts are not particularly toxic, the formulation may be administered for as long as necessary to achieve the desired therapeutic effect.
[0083] In the case where an intravenous injection or infusion composition is employed, a suitable dosage range for use is, e.g., from about 0.01 to about 150 mg per kg body weight of Magnoliaceae plant extracts daily.
[0084] Again, any suitable route of administration may be employed for providing the consumer or patient with an effective dosage of Magnoliaceae plant or plant extracts composition of this invention. Dosage forms include tablets, troches, cachet, dispersions, suspensions, solutions, capsules, gel caps, caplets, compressed tablets, sustained release devices, patches, and the like.
[0085] The dietary supplements and pharmaceutical compositions of the present invention comprise Magnoliaceae plant or plant extracts as the active ingredients, as well as pharmaceutically acceptable salts thereof, and may also comprise a pharmaceutically acceptable carrier, and optionally, other therapeutic ingredients.
[0086] The dietary supplements and pharmaceutical compositions include compositions suitable for oral and parenteral (including subcutaneous, intramuscular, intrathecal, intravenous, and other injectables) routes, although the most suitable route in any given case will depend on the nature and severity of the condition being treated.
[0087] In addition, the Magnoliaceae plant or plant extracts carrier could be delivered via charged and uncharged matrices used as drug delivery devices such as cellulose acetate membranes, also through targeted delivery systems such as liposomes attached to antibodies or specific antigens.
[0088] In practical use, Magnoliaceae plant or plant extracts can be combined as the active ingredient(s) in intimate admixture with a pharmaceutical carrier according to conventional pharmaceutical compounding techniques. The carrier may take a wide variety of forms depending on the form of preparation desired for administration, e.g. oral or parenteral (including tablets, capsules, powders, intravenous injections or infusions). In preparing the compositions for oral dosage form any of the usual pharmaceutical media may be employed, e.g., water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents, and the like; in the case of oral liquid preparations, e.g., suspensions, solutions, elixirs, liposomes and aerosols; starches, sugars, micro-crystalline cellulose, diluents, granulating agents, lubricants, binders, disintegrating agents, and the like in the case of oral solid preparations e.g., powders, capsules, and tablets. In preparing the compositions for parenteral dosage form, such as intravenous injection or infusion, similar pharmaceutical media may be employed, e.g., water, glycols, oils, buffers, sugar, preservatives, and the like know to those skilled in the art. Examples of such parenteral compositions include, but are not limited to Dextrose 5% (w/v), normal saline or other solutions. The total dose of the Magnoliaceae plant extracts may be administered in a vial of intravenous fluid, e.g., ranging from about 0.7 to about 14 mg per kg body weight of Magnoliaceae plant extracts. The volume of dilution fluid will vary according to the total dose administered and over the length of the period of time of administration.
