Stroke is a very common disease in our life. It is extremely dangerous and can cause serious consequences such as hemiplegia, mouth and eyes distortion and hemiplegia, causing great damage to families and society. Today we will understand the concept of stroke and what are the clinical manifestations. Stroke is caused by the imbalance of qi and blood, imbalance of yin and yang on the basis of labor, weariness, internal injury, worry, anger, climate change, addiction to tobacco and alcohol, or prolonged illness, which leads to the imbalance of yin and yang in the internal organs, and the rebellion of qi and blood directly to the brain, resulting in the onset of cerebral vein paralysis or blood overflow outside the cerebral veins. It is equivalent to the diseases of cerebral infarction and cerebral hemorrhage in Western medicine. In ancient times, there were four major internal diseases in Chinese medicine that were difficult to treat, namely “wind, consumption, dropsy and diaphragm”, and wind accounted for the first of these four major diseases, indicating the degree of difficulty in treating the disease in ancient times. Most of the “wind” mentioned here belonged to stroke, which is now called cerebrovascular disease. Chinese medicine is good at taking analogy, according to the observation of nature, the ancients found that the wind is flowing, where the wind passes, the trees sway and sway, and the river waves surge. Based on this life experience, the ancients associated the human body with the feeling of trembling limbs and dizziness when certain diseases occur, so they thought that most of the objects that can shake in nature are blown by the wind, so the shaking of the human body is also related to the wind, so the disease that can cause dizziness and trembling limbs is called stroke. In the classic work of Chinese medicine “Huangdi Neijing”, there is a statement that “all winds and dizziness belong to the liver”, and the liver belongs to the organ of wind and wood in Chinese medicine. This statement not only suggests the cause of stroke disease, but also identifies its location and provides a direction for treatment. Later generations of physicians have continued to summarize and improve on this basis, laying a profound foundation for the treatment of stroke in Chinese medicine.
