There is no such thing as “which three herbs lower blood pressure”. Hypertension is often associated with dizziness and other symptoms, which can be categorized as “dizziness” in Chinese medicine. Clinically, according to the different types of symptoms, we can choose Tianma Hook Teng Drink, Semixia Atractylodes Macrocephalae Tianma Soup and other traditional Chinese medicine formulas for treatment. Vertigo includes dizziness, blurred vision or blackness in front of the eyes, and its common types in TCM include hyperactivity of liver yang (excessive liver yang, causing dizziness, dizziness, headache and other symptoms), phlegm-dampness obstruction (phlegm-dampness staying in the spleen and stomach), blood stasis obstructing the orifices, qi and blood deficiencies, and insufficiency of kidney essence. 1. Hyperactivity of Liver-Yang (Liver-Yang is strong, causing dizziness, dizziness, headache and other symptoms) manifests as dizziness, tinnitus, distension of the head and eyes, impatience, irritability, bitter taste in the mouth, insomnia and excessive dreaming, which is aggravated when one encounters troublesome labor and depression, and so on. Treatment should calm the liver and submerge the yang (inhibit too much rising yang qi in the liver), clear the fire and quench the wind. Tianma Hook Teng Drink can be chosen. This formula is composed of Tianma, Hook Teng, Shihjianming, Chuan Niu Knee, Sang Zhusheng, Cortex Eucommiae, Gardenia, Scutellariae Radix, and Yi Mu Cao. 2. Phlegm-dampness obstruction (phlegm-dampness staying in the spleen and stomach) manifests as vertigo, head heavy like a blindfold, or accompanied by rotating vision, chest tightness and nausea, vomiting phlegm and saliva, etc. The treatment is to dissolve phlegm and dispel dampness. The treatment is to resolve phlegm and dampness, strengthen the spleen and stomach (to restore the functions of the spleen and stomach). This formula can be used in the form of Semixia, Rhizoma Atractylodis Macrocephalae, and Tianma Tang. This formula is composed of Semixia, Rhizoma Atractylodis Macrocephalae, Tianma, Tangerine, Poria, Glycyrrhiza, Ginger and Jujube. The above formula should be used after identification by a physician and should not be taken blindly by oneself to avoid adverse consequences. If you have high blood pressure, it is recommended that you go to the hospital as soon as possible to be treated by a professional doctor and take antihypertensive drugs regularly to avoid delaying your condition.
