Improved rGyud bZhi
In the 12th century, Dr. Yuthog Yonten Gonpo the Younger refined the medical canon rGyud bZhi, which became the fundamental work of Tibetan medicine. This book is also used in modern Tibetan medicine.
Dr. Yuthog Yonten Gonpo's point of view was that to become a good doctor, one must first develop the doctor's mind (ethics, empathy, altruism, etc.). When dealing with a patient, the doctor uses not only his physical body, but also his benevolent and sincere mind. Yuthogpa focused on inner therapy - developing the mind through meditation, rituals, sounds and chanting of mantras.
