The drugs of herbal, herbo-mineral and animal origin have been used by the traditional healers to maintain health and treat diseases since the dawn of civilization. These medicines are widely used by the practitioners of Indian Systems of Medicine comprising of Ayurveda, Unani, Homeopathy and Siddha, and in the Chinese System of Medicine. Due to adverse side effects coupled with the development of resistance in the pathogens to synthetic drugs, "Traditional System of Medicine" and use of plant derived drugs are also becoming popular in Western countries including USA.
