Patients with hypertension have some benefits from eating garlic, which contains a variety of bioactive substances such as allicin and other nutrients with some biological effects such as antioxidant and anti-inflammatory, and also has some cardiovascular benefits, but it cannot replace antihypertensive drugs and other lifestyle modifications such as low salt and low fat diet, weight control, exercise, etc. In addition, the consumption of garlic should pay attention to the stimulation of the gastrointestinal tract. The diet should also pay attention to nutritional balance, with more intake of fresh vegetables and fruits, high-quality protein, etc. The improvement of lifestyle habits needs to be accompanied by standardized treatment with antihypertensive drugs to control blood pressure within the normal range and prevent damage to target organs such as heart, brain and kidney caused by hypertension.
