The use of plant materials for preparations of ayurvedic tonics has been known since ancient periods. The use of digestive candies and health tonics are at great demand in India. Further, the enormous use of organochlorine pesticides (OCPs) in developing countries has been of serious concern because of their persistant nature. Herbal products prepared using parts of the plants for human consumption used as drugs, tonics, toiletories, cosmetics etc may also contain significant level of OCP residues.
