The main component of alcohol is alcohol (i.e. ethanol), and although there is no consensus on the harmful effects of alcohol, it is widely recognized that long-term consumption of large quantities of high alcohol can damage nerve cells in the brain, anesthetize the cerebral cortex, affect intelligence and promote arteriosclerosis. For stroke patients, the cerebral blood vessels are already diseased and the cerebral nerve function is already affected, so when they are stimulated by alcohol, it is possible that the central nervous system will be excited or in a state of inhibition. Of course, intermittent, small amounts of low-concentration, high-quality wine or medicinal wine can be beneficial for the recovery of patients with post-stroke sequelae. Therefore, patients with acute stroke must abstain from alcohol, and patients with post-stroke sequelae must also limit alcohol to intermittent, small amounts of low-concentration medicinal wine or good quality wine when needed for treatment.
