Observation of the Effect of "Tongmailing" on Hypertension
 
　　
2030 cases of hypertension were treated by Tongmailing (activating vessel), among them l005 cases were male and l025 were female, 232 were critical cases, 847 were at stage I, 789 were at stage II and l62 were stage III. According to differentiation of symptoms and typing of TCM, l502 were type of Yin deficiency of the liver and kidney 528 were type of the liver predominance of Yang and 258 were other types. With obvious effect: l779 cases (87.6%), with effect: l69 cases (8.3%), no effect: 82 cases (4.l%).
　　
The result shows that Tongmailing is an effective anti-hypertension traditional Chinese herb. Tongmailing is a key scientific and technological project of Shanxi Province No. 92KY-G22) in the period of the eighth 5-Year plan. It was designed based on the research result on hypertension by TCM theory combined with modem medicine. The herb consists of Radix astragal seu Hedysari, Rhizoma Gastrodiael, Cortex Eucormiae, Chalcanthitum, raw Radix Rehmanniae. Herbaceous Peony Flos Chrysanthemi, Radix Polygalae, Os Draconis, Concha Ostreae, Spica Prunellae. While Tongmailing can reduce blood pressure slowly and enduringly, it does not effect the metabolism of blood-fat, blood sugar and electrolytes. Study on pharmacology and pharmacodynamics shows that it can also increase remarkably cardiac output and increase blood flow of kidney and brain. D50 was not measured by both acute and chronic toxicity tests. The characteristics of blood flow dynamics are beneficial to the treatment of hypertension and to improving life quality of the patients. Therefore, Tongmailing is an idea anti-hypertension traditional Chinese preparation.
