Wormwood has no particular efficacy in diabetic patients, and there are no clinical studies showing that it has a blood sugar-lowering effect. Traditional Chinese medicine believes that wormwood has the efficacy of regulating qi and blood, expelling cold and dampness, warming menstruation and stopping bleeding. However, it has not been proven in clinical trials to lower blood sugar. Should be used under the guidance of a doctor, improper use is likely to have adverse effects on the body. For the management of blood sugar in diabetic patients, it is also necessary to control the diet, such as low-sugar, low-fat, low-salt diet, increase the reasonable exercise, such as swimming, jogging, etc., as well as the use of hypoglycemic drugs, such as metformin, insulin, etc. to carry out treatment. Do not trust the traditional Chinese medicine. Diabetic patients should seek timely medical treatment to maintain their blood glucose within the target range through a combination of diet therapy, exercise therapy and medication, and monitor blood glucose fluctuations on a regular basis.
