ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to herbal compositions. More particularly, this invention relates to an herbal composition capable of reducing inflammation in bones and joints in animals, particularly humans, while promoting safe and restful sleep. The present invention further relates to methods of using such herbal composition to reduce inflammation in bones and joints in animals, particularly humans, while promoting safe and restful sleep.
Arthritic disorders, including rheumatism, osteoarthritis, dysplasia, lupus, bursitis, and gout, are all characterized by inflammation and pain in bones, joints, muscles, and related connective tissues. Most of the forms are progressive. Bone and joint inflammation is a scourge of both animals and humans. Those who suffer from inflammation experience pain and discomfort and may, in advanced cases, lose the effective use of inflamed joints. Thus, the goal of therapeutic methods for treating bone or joint inflammation is the relief of pain and discomfort and the restoration of use of inflamed joints.
Natural ingredients, e.g., herbs, have been used to treat bone and joint inflammation, especially in eastern countries, and, increasingly, in western countries. Compositions composed of natural ingredients and said to be useful in reducing inflammation are disclosed, e.g., in U.S. Pat. Nos. 5,494,668; 5,683,698; 5,916,565; 5,854,291; and 5,910,307.
U.S. Pat. No. 5,494,668 (Patwardhan) discloses a method of treating degenerative musculoskeletal diseases such as rheumatoid arthritis and osteoarthritis in an animal, typically a human, involving administering (typically enterally) to the animal beneficiated extracts of the ashwagandha, sallai Guggul, turmeric, and ginger plants, in a predetermined proportion relative to each other with or without other biologically active inorganic ingredients.
U.S. Pat. No. 5,683,698 (Chavali et al.) discloses an orally administered herbal formulation for reducing or alleviating symptoms associated with rheumatoid arthritis, osteoarthritis, and reactive arthritis and for reducing the production of pro-inflammatory cytokines, wherein the formulation contains herbal extracts taken from Alpinia, Smilax, Tinospora, Tribulus, Withania, and Zingiber plants.
U.S. Pat. No. 5,916,565 (Rose et al.) discloses an orally administered composition for prophylaxis and therapy of joint and connective tissue disorders in vertebrates, wherein the composition contains metabolic precursors, herbal phytochemicals, and palatability agents. Specific herbal phytochemicals disclosed include cayenne, ginger, turmeric, yucca, Devil's claw, nettle leaf, Black Cohosh, alfalfa and celery seeds.
U.S. Pat. No. 5,854,291 (Laughlin, et al.) discloses a topically-applied pain reliever composition for treating such discomforts as arthritis pain, the composition being composed of capsaicin and, optionally, a plant extract selected from the group consisting of nettle extract, yarrow extract, coltsfoot extract, birch extract, rosemary extract, horsetail extract, ginger extract, chamomile extract, comfrey extract, lavender extract, and bergamot extract.
U.S. Pat. No. 5,910,307 (Kwak, et al.) discloses a combined medicinal plant composition for alleviating acute/chronic inflammation, composed of Clematis Radix, Trichosanthes root, and Prunella Herba (which contains oleanolic acid ursolic acid) in a certain ratio.
Certain enzymes appear to play a role in causing inflammation. One of the features of inflammation is increased oxygenation of arachidonic acid which is metabolized by two enzymic pathways—the cyclooxygenase (CO) and the 5-lipoxygenase (5-LO) pathways—leading to the production of prostaglandins and leukotrienes, respectively. Prostaglandins and leukotrienes are mediators of inflammation. Therapies designed to inhibit cydooxygenase and/or lipoxygenase activity are therefore of great interest.
There are two forms of the cyclooxygenase enzyme: cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2). The latter form, i.e., COX-2, appears to play a key role in inflammatory processes. Recent scientific studies suggest that inhibiting the COX-2 enzyme may be an effective way to reduce inflammation without the side effects associated with irreversible COX-1 inhibition. In addition, recent scientific studies also suggest that COX-2 inhibition may serve an important function in promoting normal cell growth in the colon, pancreas, breast tissue and other organ systems.
Drugs are being developed which are intended to selectively inhibit COX-2 with minimal effect on COX-1. However, despite the emphasis on COX-2 inhibition, these drugs appear to have serious side effects, e.g., a breakdown in digestive protective mucus and prevention of normal healing processes. For example, non-steroidal anti-inflammatory drugs (NSAIDS) can have a variety of toxic side effects such as, e.g., gastric erosion and adverse effects on kidneys and liver, and may inadequately regulate the cellular immune functions and secretions of various cytokines.
Several herbs have been found to inhibit the COX-2 enzyme.
For example, holy basil has been found to possess significant anti-inflammatory properties and is capable of blocking both the cyclooxygenase and lipoxygenase pathways of arachidonate metabolism. Ursolic acid and oleanolic acid (less active), the marker constituents of holy basil, have been found to a significant COX-2 inhibitory effect.
Shogaol, a pungent component of ginger, has been found to inhibit cyclooxygenase. Eugenol, another constituent of ginger, has also been found to be a 5-lipoxygenase inhibitor and to possess potent anti-inflammatory and/or anti-rheumatic properties.
Scutellaria baicalensis also has been found to inhibit the COX-2 enzyme.
According to the USDA database, green tea contains six constituents having cyclooxygenase-inhibitor activity. According to the Napralert database, green tea contains fifty one constituents having anti-inflammatory activity. The polyphenols in green tea were found to cause a marked reduction in cyclooxygenase-2. Flavan-3-ol derivatives (+)-catechin, also present in green tea, have been reported to be COX-1 and COX-2 inhibitors. In addition, salicylic acid, another constituent of green tea, also has been found to be a COX-2 inhibitor.
Berberine, found in barberry and Chinese goldthread, has been found to inhibit COX-2 without inhibiting COX-1 activity.
Inflammation is also mediated by oxygen-derived free radicals. Free radicals degrade hyaluronic acid, modify collagen and perhaps proteoglycan structure and/or synthesis, alter and interact with immunoglobulins, activate degradative enzymes and inactivate their inhibitors, and possibly participate in chemotaxis. It is desirable to scavenge and detoxify free radicals before they reach the affected area.
Herbs which can scavenge free radicals include, e.g., holy basil, turmeric, and scutellaria baicalensis.
Although herbs having anti-inflammatory and antioxidant properties are known, it is continually desirable to provide anti-inflammatory/antioxidant herbal compositions which also promote safe and restful sleep for those which wish to take anti-inflammatory compositions at night.
Although having both anti-inflammatory and antioxidant properties, green tea, barberry and Chinese goldthread also tend to be slightly stimulating. Thus, anti-inflammatory and/or antioxidant compositions containing these herbs should not be taken at night as they can interfere with sleep.
Melissa and valerian are known to provide optimal sleep quality and are each a source of anti-inflammatory compounds. However, it is still desirable to provide compositions having improved anti-inflammatory and sleep-promoting benefits than would be obtained with compositions containing either melissa or valerian alone.
Accordingly, a primary object of this invention is to provide an orally administered herbal composition capable of effectively reducing bone and joint inflammation in animals, particularly humans, while promoting safe and restful sleep.
A further object of this invention is to prov
