Sweet and sour garlic mainly treats high blood pressure. Preparation and consumption method: Place the garlic head in the sweet and sour liquid (the degree of sourness and sweetness is determined by yourself), soak it for about 2 to 3 weeks, and then you can consume it. If it feels too spicy, soak it for a little longer. Eat 1~2 on an empty stomach every morning, and drink it with sweet and sour juice. Taking it for half a month is a course of treatment.
