Witchcraft, Ayurveda, homeopathy and allopathy evolved over time and exist today. While witchcraft was based on the belief that evil spirits inflict disease, Ayurveda in India and Yin-Yang in China introduced the concept that the cause of disease is physical and not supernatural, which led to a search for physical remedies from plants, animals and soil. Homeopathy recognised that drugs assist the body to cure itself. Given the complexity of the biological system and disease processes, none of the medical disciplines can fully meet the expectations of the patient and therefore, have managed to survive until now. The dismal state of healthcare system in India, coupled with strong feudal culture, also caters to the survival of both rational and irrational medical disciplines and practices.
