Abstract OBJECTIVE: To observe the effect of moxibustion of Baihui (GV 20) on the hemodynamics of internal carotid artery in health subjects so as to study its underlying mechanism of moxibustion in the treatment cerebrovascular disorders. METHODS: Thirty healthy male volunteer students between 20 and 22 years in age were enrolled into this study. Qm (mean blood flow), Vm) (mean velocity of blood flow), Vmax (maximal velocity of blood flow), Vmin (minimal velocity of blood flow), Wv (pulse wave velocity), Zcv (characteristic impedance), Rv (peripheral resistance), DR (dynamic resistance), CP (critical pressure) and DP (difference of pressure) of the right and left common carotid arteries were measured before and after moxibustion of GV20 (5-10 min each time, once daily, 5 times altogether) by using CBA CV-300 Cerebrovascular Hemodynamics Detector. RESULTS: Following moxibustion of GV20, Qm, Vm and Vmin of both right and left common carotid arteries increased significantly (P < 0.01); while Rv and DR of the brain artery lowed evidently (P < 0.05); The rest indexes had no significant changes (P > 0.05). CONCLUSION: Moxibustion of Baihui (GV 20) can significantly raise the velocity of blood flow of the common carotid artery and low the resistance of blood vessels.
