Berberine hydrochloride is not a treatment for hypertension. Berberine hydrochloride is mainly used for patients with gastroenteritis, and patients are advised not to use the drug indiscriminately. Some people may see some web pages saying that berberine hydrochloride is useful for blood pressure and blood lipids, but there is no clinical evidence of this, and the drug is not used clinically for antihypertensive treatment. Berberine hydrochloride and other regular antihypertensive drugs are drug components that may cause side effects, so it is important for patients with hypertension to be treated with regular antihypertensive drugs. Generally, people with hypertension can help prevent hypertension complications by lowering their blood pressure with a regular program. For people with hypertension, it is recommended that lifestyle interventions be carried out on the basis of regular medication, a low-salt, low-fat diet, more exercise, and quitting smoking and drinking.
