Recently, a friend recommended a tea drink that can reduce blood pressure: 3 grams each of chrysanthemum, sophora flower, and green tea. Put it in a cup, brew with boiling water, cover tightly and soak for 5 minutes. Take 1 dose a day, drink frequently at any time. I drank this method for a week, and I felt better and my anger was less intense. I would like to ask an expert to analyze the reason.

Professor Yang Li of the Graduate School of the China Academy of Chinese Medical Sciences commented: Traditional Chinese medicine classifies high blood pressure into the category of "dizziness and headache". Traditional Chinese medicine believes that there are many causes of high blood pressure, such as inflammation of the liver-fire, turbid phlegm, deficiency of qi and blood, liver and kidney yin deficiency, blood stasis blocking the orifices, disturbance of wind and fire, etc. Therefore, when it comes to antihypertensive medication, Chinese medicine places special emphasis on syndrome differentiation and treatment.

This recipe is more suitable for patients with hypertension caused by liver-fire inflammation, wind-fire disturbance, and liver and kidney yin deficiency. The main symptoms of liver-fire inflammation type are dizziness and headache, red eyes and mouth, fullness of chest and ribs, irritability, etc. The main symptoms of wind-fire disturbance type are dizziness and tinnitus, headache and swelling, fatigue or anger will aggravate the condition, poor sleep, dreaminess, bitter mouth, red tongue, etc. The liver and kidney yin deficiency type mainly shows dizziness, tinnitus, dry eyes, insomnia and dreaminess, soreness and weakness of waist and knees, frequent nocturia, etc. According to the reader's description, his disease may be high blood pressure caused by inflammation of liver fire.

In this prescription, chrysanthemum is slightly cold in nature, pungent, sweet, and bitter in taste, and returns to the lung and liver meridians. It is a commonly used Chinese medicinal material for the treatment of liver diseases. It has the effects of calming the liver and extinguishing wind, and treating headaches, dizziness, and red and swollen eyes. In addition, the chrysanthemum used for brewing in this recipe can be white chrysanthemum, which is more gentle. Sophora japonica has a bitter taste and slightly cold nature. It returns to the liver and large intestine meridian. It has the effects of cooling blood and stopping bleeding, clearing the liver and purging fire. It is used for blood in the stool, hemorrhoids, bloody dysentery, metrorrhagia, vomiting blood, epistaxis, liver heat, red eyes, headache and dizziness. "Yilin Zhuan Yao" records that Sophora japonica can "relieve lung irritation, purge heart fire, clear liver fire, and strengthen kidney water." Modern research shows that the quercetin in Sophora japonica can expand coronary blood vessels and improve myocardial circulation; Sophora japonica liquid and Sophora japonica tincture have temporary effects on anesthetized dogs and cats. Significantly lower blood pressure. Rutin and its preparations in Sophora japonica have antihypertensive effects, and quercetin can also reduce blood pressure in a short period of time. In addition, Sophora japonica also has a good antioxidant effect. Regular drinking can not only improve immunity, but also play a role in beauty. However, due to the cold nature of Sophora japonica, people with spleen and stomach deficiency should use it with caution.

Green tea is unfermented tea, and its tea soup is called the "national drink" in my country. It is cold in nature and pungent in taste. It belongs to the liver, spleen, lung, and kidney meridians. It can clear away heat, relieve troubles, soothe the throat, and detoxify. "Xinhua Compendium of Materia Medica" records that green tea is mainly used to treat hypertension, stomatitis, boils, chronic laryngitis and gynecological adnexitis. It also has antioxidant, hypolipidemic and diuretic effects. The three kinds of medicines substituted for tea have certain auxiliary therapeutic effects on high blood pressure caused by corresponding reasons. However, since these three medicinal materials are relatively cold in nature, they are not suitable for people with cold stomach and weak pulse.
