The Ministry of Ayurveda, Yoga and Naturopathy, Unani, Siddha and Homoeopathy of the Government of India regulates training in Siddha medicine and other traditional practices grouped collectively as AYUSH. Practitioners are called "siddhars" ("vaithiyars" in Tamil), and may have formal training with advanced degrees, such as BSMS (Bachelor in Siddha Medicine and Surgery), MD (Medical Doctor, Siddha) or Doctor of Philosophy (PhD). The Central Council of Indian Medicine, a statutory body established in 1971 under AYUSH, monitors education in areas of rural Indian medicine, including Siddha medicine.
