The risk of carotid plaque mainly lies in unstable plaque, that is, plaque that is unstable and easy to fall off on the blood vessel wall. When the whole or part of the plaque falls off, it becomes an embolus in the blood flow, which reaches the brain with the blood flow and blocks the distal cerebral artery, leading to embolic events. Depending on the size of the blocked blood vessel and the blocking time, it will lead to different results. Small blood vessel blockage is mild or asymptomatic, while large blood vessel blockage will lead to sudden hemiplegia and aphasia. If the blockage time is short, there will be transient slurred speech, dizziness, numbness or weakness of limbs. Severe cases may cause blindness, hemiplegia and even life-threatening!

For the existing plaque in the body, statins and fibrates are commonly used in western medicine to treat plaque at present, and dissolving plaque, reducing turbidity and Tongmai decoction is used in traditional Chinese medicine.

Dissolving plaque, reducing turbidity and promoting pulse decoction can stabilize or melt the already formed atherosclerotic plaque, increase the thickness of plaque envelope, prevent plaque rupture, improve vascular sclerosis and prevent the further development of the disease; At the same time, it can also repair the damaged vascular endothelium, make the vascular endothelium smooth again, so that the lipids in the blood are not easy to attach to it, thus reducing the environment for plaque formation.
