In the Journal of Chinese Medicine, there is a useful synopsis of the main acupoints used in TCM treatment of headaches (17 local points, 21 adjacent and distal ones) (Deadman, Al-Khafaji and Baker 1998). In the EA and other clinical studies for mixed headache types in the database, the most commonly used points are Fengchi (GB 20), Taichong (LIV 3) and Hegu (LI 4), with others such as Tianzhu (BL 10), Shuaigu (GB 8), Zusanli (ST 36) and Taiyang (M-HN-9) trailing behind and a scattering of other points used even less frequently. A number of authors emphasise TCM differentiation; others stress that local treatment is best carried out, at ashi points. Certainly in studies on experimental dental or other head pain local points have sometimes proved more effective than distal ones such as Hegu (LI 4).
