There's a very famous case of frostbite so bad that the doctors insisted that the patient needed amputation(severance? Not sure how you say cutting off toes) but a traditional Korean doctor cured it only with acupuncture and some herbal medicine. The patient recently made an interview about it as well. I was able to find this related paper as well.
Still not sure if this can be achieved only with some form of placebo. Guess I am too familiar with the idea of acupuncture being real?
