AYUSH is an acronym for Ayurveda, Yoga and Naturopathy, Unani, Siddha, and Homoeopathy.
Sowa-Rigpa, a traditional Tibetan system of medicine, was officially recognized by the Government of India in 2010 and added to the list of officially recognized systems under the AYUSH framework.
While Unani, Siddha, and Homoeopathy were already recognized systems being promoted alongside Ayurveda, Sowa-Rigpa is the most recent addition to this list for focused development and promotion under the AYUSH Ministry (formerly Department).
