Synergistic composition for osteoarthritis
The present invention relates to synergistic compositions for the treatment of one or more associated conditions of arthritis or rheumatoid arthritis osteoarthritis. More particularly, novel synergistic compositions which comprises a combination of therapeutically effective amounts of: a) an alcoholic/hydroalcoholic extract of Tamarindus indica seed comprising proanthocyanidins either alone or in combination with water extract of Tamarindus indica seed comprising polysaccharides, b) a Curcuma longa rhizome extract comprising curcuminoids, c) optionally containing pharmaceutically or nutraceutically or dietetically acceptable carriers/excipients. The invention also relates to a method of treating one or more associated conditions of arthritis or rheumatoid arthritis or osteoarthritis using synergistic composition.
