The Unani medicine system was introduced to India about a thousand years ago by the Muslims and became indigenous to the country. It is now practiced in the Indo-Pakistan subcontinent. The Unani physicians who settled in India have added new drugs to the system and therefore the Unani system practiced in India is somewhat different from the original Greek form.
The Amchi system of medicine, also known as the Tibetan System, is practiced in northern India and some other regions of the Himalayas particularly by the Buddhists. This system traces its origin to Ayurvedic system to include treatments by herbs, minerals, animal organs, spring and mineral waters, puncturing of veins, mysticism, and spiritual powers.
Naturopathy (natural cure) is not only the system of treatment but a way of life. It is often referred to as drugless treatment of diseases. Naturopathy is based on the ancient practice of simple laws of the nature. This system is closely allied to Ayurveda as far as the fundamental principles are concerned.
