Can hibiscus tea lower blood pressure?
Roselle, also known as Hibiscus sabdariffa, is generally effective in lowering blood pressure. The detailed analysis is as follows:
Hibiscus sabdariffa is a plant recognized as both food and medicine, suitable for daily consumption or used medicinally in combination with other traditional Chinese herbs to treat various conditions. It helps relieve fatigue, promotes skin health, and lowers blood pressure. This effect is due to its rich content of hibiscus acid, which reduces total cholesterol and triglyceride levels in the body and aids in blood vessel dilation, thereby contributing to blood pressure reduction. Therefore, hibiscus tea can serve as an adjunctive treatment for lowering blood pressure. For individuals seeking blood pressure control, in addition to drinking hibiscus tea, medications such as nifedipine controlled-release tablets, sacubitril/valsartan sodium tablets, and benazepril hydrochloride tablets may be used under medical supervision.
The effect of hibiscus tea is relatively limited. If adverse symptoms occur, prompt medical attention is necessary, and patients should follow their doctor's advice regarding treatment. Additionally, during this period, maintain a light diet and avoid smoking, alcohol, and spicy, raw, cold, or greasy foods, such as chili peppers, cold beverages, and fatty meats.
