The cause of hypertension, or essential hypertension, is unknown, with a reported incidence of more than 11% of the population. The effects on human health are familiar. Most of the patients can be controlled with western medicine, but some of them seek Chinese medicine consultation and treatment with poor effect of western medicine. According to the experience of treating hypertension with Chinese medicine in recent years, the overall effect is still good. Most patients have obvious effect of lowering blood pressure in a short period of time, and many patients can stop the medication after consolidating the treatment for a period of time. And there are no obvious toxic side effects of Chinese medicine. According to clinical observation, I believe that hypertensive patients can be classified into two main types in terms of clinical evidence. One is the fire-exuberant type, and the other is the Yang-deficiency type. The fire-exuberant type is mainly manifested in liver and gallbladder fire or yin deficiency fire; the yang deficiency type is mainly based on spleen and kidney yang deficiency. Clinical manifestations include dizziness and headache. In the case of liver and gallbladder fire, irritability, bitterness and dry mouth, red tongue with yellow coating, and stringiness of the pulse are the main symptoms. In case of Yin deficiency, there are symptoms such as irritability and heat in the heart, palpitations and insomnia, red tongue with less coating, and fine pulse. Yang deficiency type manifests with coldness, soreness and weakness of the waist and knees, fatigue, pale tongue with white fur and sunken pulse. In the treatment, we should follow the principle of dialectical treatment and then combine the pharmacological research of modern medicine to form the prescription. The type of liver and gallbladder fire is used to clear liver fire and submerge liver Yang and has the effect of lowering blood pressure: gentian grass, grass cassia, wild chrysanthemum, Yin Chen, scutellaria, gardenia, rhubarb and so on. Yin deficiency fire type use to nourish Yin and submerge Yang and at the same time has the effect of lowering blood pressure: asparagus, hooked vine, white chrysanthemum, Tribulus terrestris, raw dragon bone, raw oyster and so on. Yang deficiency type use both warming the spleen and kidney Yang Qi and obvious antihypertensive effect: Xianmao, Epimedium, Eucommia, Bacopa monniera, Acanthopanax, Bupleurum and other drugs. It is clinically proven that as long as the evidence is correct, and then refer to the modern pharmacological research, the right medicine will have twice the clinical effect with half the effort, which is also the original purpose of advocating “ancient for the present, foreign for Chinese”. The purpose of treatment is to adjust the balance of yin and yang of the body, so that the function of the internal organs can be coordinated, which is often referred to as “adjusting yin and yang, in order to calm the period”, and then the body will be healthy as usual.
