The function of aged vinegar is to activate blood circulation and remove blood stasis, remove blood stasis and relieve pain, and it can play the function of softening blood vessels, especially suitable for people with calcified atherosclerosis. Calcified atherosclerosis of arteries occurs when calcium is deposited on the inner side of the arterial wall, and aged vinegar, because it contains acetic acid, binds the calcium ions deposited in the arterial wall to form bound calcium ions that are carried away from the hardened area through the bloodstream, and then discharged out of the body in the kidneys in the form of urine, so that it achieves relevant therapeutic effects. It is worth noting that vinegar softens the blood vessels, but also causes some stimulation to the blood vessels, causing the contraction of the blood vessels, especially for the gastrointestinal part of the blood vessel contraction is relatively more obvious, so it is not possible to use it for a long time in large quantities.
