In almost all the countries, traditional and folk herbal medicines have been extensively used since times immemorial for healthcare. Ancient religious texts are replete with references on the use of herbs with medicinal properties. Because of the local beliefs and practices and also from cost considerations herbal medicines remain a popular mode of treatment in the developing countries. In the industrialized society also, the rising cost of prescription drugs and ensuing side effects of the treatment makes it highly attractive to use the traditional medicine.
