Tibetan doctors rely on Medicine Buddha for their healings. Regular practice with the Medicine Buddha also empowers one to heal others. Medicine Buddha is a refuge in times of illness. Around the world, literally millions call out the name or mantra of Bhaisajyaguru (भैषज्यगुरु). It is even written in the sutras that if you speak the name of the Medicine Buddha in the ears of a dying animal or human they will be ensured good rebirth regardless of their past karma.
