Vaidyaratnam P. S. Warrier, a scholar in whose honour the Government of India have issued a postage stamp, founded Arya Vaidya Sala in 1902, at Kottakkal, a small town in Malappuram district, in the Indian state of Kerala. It began as a small clinic for outpatient treatment and sale of ayurvedic medicines. Fifteen years later, Warrier established the Arya Vaidya Patasala (School of Ayurvedic Medicine), in the town of Kozhikode teaching under the Gurukula method. The school was shifted later to Kottakkal and has transformed itself into a Medical College, Vaidyaratnam P. S. Varier Ayurveda College, affiliated to the  Kerala University of Health Science

Warrier was conferred the title of Vaidyaratnam (jewel among physicians) by the Government of British India in 1933. After the death of P. S. Warrier, his nephew, P. Madhava Warrier (P. M. Warrier) took over the position as the Chief Physician and became the first Managing Trustee of the charitable trust in 1944.
