Stroke is a disease name of traditional Chinese medicine, and it is also the general name and common name of acute cerebrovascular disease. It is a kind of sudden hemiplegia with sudden syncope and unconsciousness as the main symptoms, accompanied by mouth-eye deviation, language disadvantage, hemiplegia or sudden hemiplegia without syncope. The occurrence of stroke is mainly due to the deficiency of qi and blood, the imbalance of yin and yang of heart, liver and kidney, and other inducements, such as life disorder, anxiety and anger, fatigue in atrioventricular chamber, satiated with wine and food, or invasion of external evils, which leads to the obstruction of qi and blood circulation, the blockage of skin tendons and veins, or the loss of yin to relieve qi, the bursting of liver yang, the movement of yang, the blood moving against qi, phlegm and fire.
