Vaidya Brihaspati Dev Triguna (21 June 1920 – 1 January 2013) was a renowned Indian Ayurvedic physician and one of the foremost experts in pulse diagnosis (Nadi Vaidyam). He received the Padma Bhushan in 1992 and the Padma Vibhushan in 2003.

Born on 21 June 1920 in Bara Pind, Jalandhar district, Punjab, he trained in the traditional gurukul system under Rajvaidya Pandit Gokul Chand and other eminent teachers in Ludhiana. He specialised in the classical art of pulse diagnosis, developing an exceptional ability to assess a patient’s condition with remarkable precision by examining the nadi.

He practised for decades from his clinic in Sarai Kale Khan, near Hazrat Nizamuddin Railway Station in Delhi, where he often saw hundreds of patients a day, many of them free of charge. He served as personal physician (Raj Vaidya) to the President of India and held several important positions, including President of the All-India Ayurvedic Congress, Director of the Central Council for Research on Ayurveda, and Chairman of the National Academy of Ayurveda. He worked actively for the standardisation of Ayurvedic medicines and the improvement of education in Ayurvedic colleges.

Triguna collaborated with Maharishi Mahesh Yogi and other leading Vaidyas to develop Maharishi Ayurveda, helping take Ayurvedic knowledge to an international audience. He lectured at medical institutions in Europe and the United States, including UCLA, Harvard and Johns Hopkins, and established Ayurveda clinics abroad.

Patients and colleagues remembered his compassion and confidence. “No illness is incurable,” he would tell those who came to him in despair. “Ayurveda has the means — we must only apply them correctly.”

Vaidya Brihaspati Dev Triguna passed away on 1 January 2013 at his home in Sarai Kale Khan. His sons, including Vaidya Devendra Triguna, continue the family tradition of Ayurvedic practice. He is remembered as a master of classical Ayurveda who combined profound traditional knowledge with a lifelong commitment to making this system of medicine accessible and respected both in India and around the world.
