The United Nations World Health Organisation lists more than 100 conditions treatable by acupuncture. There is a growing amount of scientific evidence showing it can help people with a range of conditions. Acupuncture is a gentle healing therapy. Each treatment builds on the former to bring about lasting change in the way Qi flows through the body, which is the key to restoring health. This is why a course of treatments is usually needed. The length of the course depends on the duration and serverity of your condition, and your constitution.
