The Yellow Emperor’s Classic of Internal Medicine is a collection of medical treatises from the pre-Qin period, which is so old that it is not easy to interpret. One of the treatises in the book talks about: “Therefore, the sages do not treat the sick to cure the unwell, and do not treat the chaos to cure the unrest. If the disease has become and after the medicine, chaos has become and after the cure, like thirst and wear well, bucket and cast cone, is not also late”. So later there was the saying of “treating the untreated”, as if to say that “before the disease is born, it can be treated”; or, another more perfect rendition: “prevent the untreated before the disease, and prevent the change after the disease”. But even the latter statement is not the original meaning of the scripture – it is just an old version of the modern view of preventive medicine. ”In the ancient texts (Zhou Li), you will find descriptions of “h first disease, itchy scabies disease, malaria and cold disease, coughing upper gas disease” and so on, and the doctors (internal medicine) who treated diseases at that time were called disease doctors. The Shuowen Jiezi says, “Sickness, sickness plus also”; the meaning of “sickness” and “disease” has different degrees of severity, and sickness is light while disease is heavy. This can explain what is “not yet sick”: it is not the absence of disease, but the budding stage of disease, or disease that has not developed seriously. For example, the book also says: “the upper work to save its sprout, the lower work to save its already”; “although the disease has not yet developed, see the red stabbed, said to cure the disease before”, are all this meaning. This is very important. The website requires that the articles must be submitted with their own classification, which is a bit difficult, because this kind of text is not considered “science”. We just need to make a clear communication to our readers or patients who trust us, that’s all.
