Acupuncture Single Point Baihui (GV 20) is the sea of yang and Zusanli (St 36) is an important point for strengthening the body. In recent years the author has used moxibustion at these points to treat 318 cases of hypertension and the results have been satisfactory. The results are summarized below.

Clinical data:
Of the 318 cases, 66 cases had suffered from hypertension for 1 year, 183 cases had suffered from hypertension for 1-5 years, 39 cases had suffered from hypertension for 6-10 years, and 30 cases had suffered from hypertension for more than 10 years. Two hundred twelve cases suffered from type II hypertension, while 106 cases suffered from type III hypertension. Thirty-six cases concurrently suffered from coronary disease, 23 cases suffered from cerebral arteriosclerosis, 17 cases suffered from hemiplegia, and 8 cases suffered from diabetes.

Therapeutic methods and outcomes:
According to The Systematic Classic (Jia Yi Jing), Bai Hui is located 1 cun and 5 fen posterior to Qian Ding (GV 19) in a depression at the vertex. It may be located directly above the tips of the auricles. In hypertension, Bai Hui will be painful, and, if it is not, the point is not Bai Hui. One first moxas Bai Hui (GV 20) and then applies moxibustion bilaterally to Zu San Li (S 36). The moxa stick is held some distance from the point and brought nearer until the patient feels a burning sensation. The moxa stick is held far enough from the skin so that the patient can bear the heat and is then removed. This process is repeated 10 times to constitute a daily treatment. Blood pressures were invariably lowered immediately after treatment. In 231 cases (72.6%), blood pressures normalized within a week. In 60 cases (18.9%), blood pressures normalized within two weeks. In 27 cases (8.5%), there was no improvement in blood pressure after two weeks. There was an overall amelioration rate of 91.5%

Discussion:
Bai Hui functions to upbear the clear and downbear the turbid, extinguish wind and boost the marrow. Zu San Li is a key point for strengthening the body. Thus, moxibustion at Bai Hui and Zu San Li upbears clear yang and downbears turbid yang, extinguishes wind and boosts the marrow, lowers the blood pressure and strengthens the body when treated by moxibustion.
