TCM, Traditional Chinese Medicine, originated in China around 100 BC. Acupuncture is one branch of TCM; it is the insertion of needles into the body to stimulate energy flow (Qi) and body functions. This type of stimulation helps keep Qi flowing properly through the channels of the body. When Qi flows properly, it carries its life force to all the organ networks. This will encourage them to work harmoniously to promote good health. Many conditions have been found to benefit greatly from treatments.​From a scientific perspective, when a needle is inserted into the skin, it sends a signal to the brain that instructs the nervous system to reduce pain or to modify a particular body function.
