3,4-dihydroxybenzoic acid is an organic acid as well as a phenolic acid, which is water-soluble and mainly presented to us as white to brown crystalline powder. It is naturally found in many vegetables, fruits and traditional Chinese medicine. At present, 3,4-dihydroxybenzoic acid is widely used in the medical industry, especially in the prevention of arteriosclerosis, which can play a good inhibitory role. Among the patients with atherosclerosis, mainly middle-aged and elderly people, the elasticity of arteries will gradually weaken with the increase of age, and there are also atherosclerosis caused by other diseases or living habits. Therefore, some foods containing 3,4-dihydroxybenzoic acid can be eaten appropriately after consulting professional and regular doctors. Hope to prevent arteriosclerosis can play a certain role.
3,4-dihydroxybenzoic acid in the medical industry can not only inhibit arteriosclerosis, but also protect our heart and its surrounding blood vessels. Usually, after intravenous injection of 3,4-dihydroxybenzoic acid, the coronary resistance will be reduced, lasting for half an hour, and can be restored to the original level about an hour later. During this period, the blood pressure of the whole body will rise slightly.
Through animal experiments, it is found that the mixture of 3,4-dihydroxybenzoic acid and protocatechuic aldehyde can mildly and slowly increase the pressure and dilate the blood vessels of the lower limbs of animals, while 3, 4-Dihydroxybenzoic acid alone has no obvious effect on the blood vessels of the lower limbs of animals.
