To understand the basics of acupuncture, it helps to familiarize yourself with the acupuncture points chart. The number of acupuncture points was originally established to correspond to the number of days in the year: 365. These points were mapped to 14 major channel lines, one channel for each of the 12 inner organs, one channel along the spine (called the governing vessel), and another along the midline of the abdomen (called the conception vessel).
Over time, the number of points identified by acupuncturists has expanded, expanding the acupuncture points chart. There are additional channels with their own sets of points, special points located off channels and complete maps of body structures by points along the ears, nose, scalp, hands, feet, wrists and ankles.
Despite the growing number of acupuncture treatment zones, most acupuncture physicians use the traditionally identified points on the 14 main channels. Each channel has a small number of points used repeatedly for their versatility in treating a wide variety of diseases.
Each point is associated with a list of disorders and diseases they can help treat, but sometimes a practitioner will select points based on the Chinese theory of balancing the qi flow — or energy flow — in the channels. So a point might be used during treatments for other kinds of disorders aside from those listed on the acupuncture points chart, due to its usefulness in this balancing process.
