Phenomenon is the external phenomenon of drugs, including not only the external characteristics of drugs (appearance, color, texture, etc.). ), including habits, functions, constraints between natural species and so on.
What you eat and what you make up are all part of the appearance of the statue, such as eating liver to make up the liver, eating whip to make up the kidney and so on.
It should be said that the theory of traditional Chinese medicine contains the meaning of law image at its origin. After the development of doctors in later generations, it reached its peak in the Song Dynasty because of the influence of science. At the end of the Northern Song Dynasty, there was Pharmacology in Shengjijing, which was the earliest monograph on pharmacology in China traditional medicine, that is, to explain pharmacology with images.
The initial pharmacology is determined by the clinical curative effect, and only after the curative effect is determined can we find a theory to explain it, thus forming a certain theory to guide clinical medication. For example, people first discovered that Schisandra chinensis can relax meridians and activate collaterals, and then explained this effect with vines that look like human meridians. That is, there is pharmacology first, and then the image is used to explain pharmacology. Later generations directly use images to deduce pharmacology, not based on clinical efficacy, so there are many unreasonable places. For example, some vines do not have the effect of relaxing meridians and activating collaterals, which directly leads to the name of pseudo-science in Chinese medicine.
