„Sure enough, Ötzi’s tattoos were on textbook acupuncture point locations. These are the same points that are used thousands of times a day to treat low back pain in modern acupuncture clinics around the world.
In addition to its better-known decorative purpose, tattooing has been practiced with a therapeutic intention for many thousands of years. With the benefit of written language and relatively stable cultural traditions, the ancient Chinese were able to refine and codify a pre-historic medical system that we now call traditional Chinese medicine.
In modern times, the practices of decorative tattooing and therapeutic needling have diverged into very different tribes. But they might claim a common ancestor—a wandering medicine man known as Ötzi.“
