Stroke is a disease characterized by sudden fainting, unconsciousness, slanting of the mouth and eyes, and paralysis of the body. In the Nei Jing, although there is no name for stroke, there are names of diseases similar to stroke such as “hitting and falling”, “partial withering”, “great syncope” and “thin syncope”. Zhang Zhongjing of the Han Dynasty was the first to propose the name of stroke in “The Fifth Book on the pulse evidence and treatment of the disease of stroke in the Jin Kui Essentials”, the original text can be found in “The disease of wind is paralysis when the body is partially paralyzed, or when the arm is paralyzed, and the pulse is weak and counted, which is caused by stroke. However, the evidence of stroke can be traced back to the Su Wen Zhi Zhen Yao Da Guan: “All the violent and strong and straight, all belong to the wind, all the wind fall dizzy, all belong to the liver”, etc. The main manifestations of this disease are sudden fainting, unconsciousness, half body paralysis, inability to speak, mouth and eyes askew, etc. The name “stroke” was first used in the medical compendium of the Ming Dynasty by Lou Ying, who believed that “stroke is also a popular name in the world…….the scripture is called ‘striking servant’, and in the world it is also called stroke The “Sutra” is called ‘hitting the servant’, which is also called stroke. According to the Internal Medicine of Chinese Medicine, the disease has a rapid onset and changes rapidly, which is similar to the characteristics of wind, so it is named as stroke. In the Treatise on the Origin of Various Diseases by Chao Yuan Fang of the Sui Dynasty, stroke was divided into five different stages of evidence, such as stroke, wind concealment, wind mouth singing, wind itching, and wind partial withering. Stroke is mainly caused by deficiency of the body, emotional and moral injury, poor diet and external evil attack, which leads to imbalance of qi, blood, yin and yang. It is similar to acute cerebrovascular disease in Western medicine. Chinese medicine believes that the unity of heaven and man, people live in the natural world, when people feel external evil, especially wind evil, and due to diet, emotion, labor and fatigue, resulting in internal Qi and blood stagnation, vascular obstruction, and finally to the internal organs of Qi and blood dysfunction, Qi and blood rebellion and stroke. 1, the invasion of external evil “Ling Shu? Stabbing section real evil chapter cloud “false wind of the thief injury also, in which people also deep, can not go from. … The evil of deficiency in the body half of the guest, its entry is deep, the internal residence of the Ying and Wei. Ying and Wei slightly weakened, then the real qi go. Evil alone, the hair for the partial wither”. Emphasis on the “internal deficiency in the evil”, weakness of Qi and blood, the veins are empty, the wind, especially in the abnormal climate change, to take advantage of the deficiency, blocking Qi and blood, the external wind led to the internal wind, then the internal dry heat, rapid development in once. 2, is the failure of the accumulation of loss of stroke disease, although the trend of younger age of onset, but still mostly seen in the elderly. Some research data show that the number of people over 50 years of age with stroke accounts for 79.5% to 86.1% of the total number of people, “Ling Shu Tian Nian” cloud “people over 40 years, Yin Qi since half”, “Qian Jin Yi Fang” also cloud: “people over 50 years, Yang Qi day decay, loss and day to day “. Older and weaker people have declining yang qi, insufficient vital energy, inability to push qi and blood to run, and qi deficiency and blood stasis. In this physiological situation, the internal organs yin and yang disorders, yin deficiency and yang hyperactivity, producing internal wind, so that the yin deficit in the lower, liver and yang scops, qi and blood rebellion, obscuring the clear orifices, thus occurring stroke. 3, emotional and mental disorders Emotional and mental is a variety of human emotions, the ancestral medicine is called the seven emotions, including happiness, anger, worry, thought, sadness, fear, shock. The Su Wen? The “pain”, “all diseases are born in qi, anger is qi up, happy is qi slow, sad is qi down, fear is qi down, fright is qi chaos, wide thinking is qi knot”, explains the different emotional disorders have different effects on the qi. Liver Qi stagnation, blood flow is not smooth; or the body Yin deficiency, water does not contain wood, and due to emotional injury, the liver Yang hyperactivity; or the five will too extreme, heart fire, wind and fire incite can trigger a stroke. And qi is the handsome of the blood, qi in and out of the lift affects the operation of the blood, so that qi rebellion on the upper, disorder of qi and blood, or qi deficiency blood stasis. Emotional and mental disorders can also lead to disorders in the functions of the internal organs, damaging yin and injuring yang, breaking the normal balance of yin and yang in the human body. It can also damage the right qi, the deficiency of the right qi can not resist external evil, thus the development of stroke. 4, the diet is not normal diet is the source of Qi, blood and fluid production, a proper and reasonable diet can make the Qi and blood flourish, Qi and blood flourish the body to play a variety of functions of the internal organs normally. If the diet is unclean, overeating, or fatty, sweet and thick taste, or alcohol, damage to the spleen and stomach to produce qi and blood, easy to lead to phlegm and damp heat, further phlegm and heat disturbing the clear orifices, heat and wind, and thus the onset of stroke. 5, excessive labor and desire “Jing Yue Quan Shu non-wind”: “where the disease, or excessive alcohol, first hurt the five organs of the true yin, yin loss in the front and Yang loss in the back, yin trapped in the lower, and Yang pan up, so that the loss of yin and Yang, the essence is not crossed, so suddenly faint collapse, suddenly fall down”. Overexertion causes deficiency of kidney essence, depletion of qi and injury to yin, resulting in deficiency of yin and wind, also for stroke.
