Introduction to Extraordinary Acupoints (including TEA, MTA and PHA)

Extraordinary Acupoints (EA) are defined as acupuncture points that have a specific location and indication but are not included in the nomenclature system of the 14 channels (12 primary channels, Du Mai and Ren Mai). I believe all acupuncturists use some of the traditional EA, among which Yin Tang, Tai Yang, An Mian and Si Shen Cong might be the most popular.
