The story of Li Shizhen's treatment with morning glory (black and white ugly);
Morning glory is a laxative, bitter and cold in nature, and has the effects of diarrhea, drainage, accumulation removal and insecticide. Throughout the history of traditional Chinese medicine, Li Shizhen, a great pharmacist in Ming Dynasty, was the first person to study and make good use of morning glory.
A 60-year-old patient came to Li Shizhen and complained of "intestinal knot disease" for decades. He defecated for a few days, which is more difficult than a woman giving birth. Taking drugs that nourish blood and moisten dryness can cause chest pain and discomfort; After taking nitroglycerin and huangzhi diuretic, I have no feeling at all. Painful for more than 30 years.
When Li Shizhen was making a diagnosis and treatment, he saw that the patient was chubby and spat in the bowl every day. Li Shizhen thinks that the patient belongs to stagnation of triple energizer, which makes the body fluid not turn into phlegm and cannot moisten intestines, but it is not caused by blood dryness, but by stagnation of wet medicine. Nitrate and yellow, which can divide blood, are useless for phlegm resistance, so they have no effect.
So Li Shizhen used morning glory powder and honey locust paste as pills and clothes. As soon as he eats it, he will benefit from defecation. It is better to eat it and be refreshed. Li Shizhen explained it this way: "Petunia can move qi and divide it into three jiao, but if qi is smooth, phlegm will disappear one by one and flow up and down quickly."
