This is probably a ganglion blocking effect. Chinese medicine should use this thing to treat rheumatic pain, and muscle relaxation has a good effect on relieving pain. Moreover, this thing is very irritating to the stomach, and the digestive tract reaction can be great, and it is easy to stimulate severe vomiting. Because of these side effects, this medicine is rarely prescribed in modern clinic. Even if the medicine is prescribed, it is usually for external use, and the new product is pounded on the swollen sores (some people say that it can cure poisonous snake bites, but I personally doubt it). So it has an alias called "Yao".
In other words, it is not recommended to dig medicine or buy food. This thing has been expelled from China's Pharmacopoeia, and it is used by folk traditions at most. Moreover, there is no evidence of clinical trials at present, and it is not a preventive drug. If you eat blindly, you will have to be hospitalized for emergency treatment to seize the scarce medical resources during the epidemic.
I have read a lot about modern research and the analysis of that report. Zhihuer said he was a professional, so I stopped mixing. The key point here is to prevent people with ulterior motives from rubbing the heat of ancient Chinese medicine books: there are several drugs named "Stephania Stephania" recorded in the book, but none of them describe the plant morphology in detail, and it is not certain whether they are the plants we know now.
In a word, even if cepharanthine is really effective in COVID-19, it is the scientific research progress of modern medicine. It is suggested to use the Japanese chemical name "Happy Hair and Peace" to treat alopecia areata. Why should Chinese medicine give an H medicine Z batch number (and I really call it "cooling blood and detoxifying", which is really a chaos to be cured)? There is no evidence that this medicine is the same as "adverse qi and phlegm on Sunday" in ancient Chinese medicine books. Moreover, we Chinese medicine practitioners have not used Stemona to treat similar symptoms now. Although the meaning of "qi in the daytime" is indeed plague and infectious disease, COVID-19's symptoms are not "not conducive to phlegm and cough".
I looked it up and used the word "plum blossom" to treat this. Everyone knows that almonds can relieve cough. Although this plum is not mentioned in the pharmacopoeia now, it should be similar. When you touched porcelain with Li Yu's branches, I said nothing. When you eat a Stephania, you begin to admire yourself blindly. Chinese medicine is not that dark, okay? It is better to go home and eat two apricots, which will save money and have fun, without pressure.
