AYUSH stands for Ayurveda, Yoga and Naturopathy, Unani, Siddha and Homoeopathy, the traditional and alternative systems of medicine in India.
The Government of India set up a Department of Indian Systems of Medicine and Homoeopathy in 1995, renamed AYUSH in 2003; a separate Ministry of AYUSH was formed in 2014.
It works for education, research, standard drugs and wider use of these systems in public health.
Through its efforts Yoga became popular worldwide, and 21 June is celebrated as International Yoga Day.
