In India, about 80% of the rural population depend on medicinal herbs and/or indigenous systems of medicine. The Present work mainly concentrating on adulteration of Psoralea corylifolia (Bakuchi) seeds with Cassia tora (Cakramardah) seeds in Bangalore local market. The plant Bakuchi is an endangered and medicinally important plant belonging to the family Fabaceae. The plant is well recognized in Indian and Chinese folkloric medicine as a laxative, aphrodisiac, anthelmintic, diuretic and diaphoretic in febrile conditions. The seeds have been recommended in the treatment of leucoderma, leprosy, psoriasis and inflammatory diseases of the skin. Adulterations and substitutions are common in raw material trade of medicinal plants. In general, adulteration is considered as an intentional malpractice. However, in raw material trade unintentional adulteration also exists. This species is very important in herbal medicine and has got varied activities. To overcome this problem in crude drugs (seeds) we investigated adulteration by Pharmacognostic parameters like, Physicochemical, Histological and TLC finger printing studies to find out adulterant. The study shows that intentionally cakramardah seeds are mixed with the bakuchi seeds. These raw herbs belong to same family, seeds and pods are morphologically similar, and identification is difficult when mixed in small quantity.
