How can Chinese medicine know the physical condition by looking at the face?

We divide skin color into main color, guest color and sick color. The so-called main color is the unchangeable skin color in a person's life. On the basis of yellowish skin color, some people will be black, white and yellow, which is normal, but when they are unhealthy, yellow, white and black are unhealthy. China people's healthy skin color should be red and yellow, bright and subtle. Bright means "bright" and moist means "moist", which implies that there is blood in it. This is healthy yellow. And unhealthy yellow is often pale yellow, dull, just like plants lack nutrition and wither.

For healthy skin color, Huangdi Neijing has a very incisive answer. "Red desire is like white wrapped in cinnabar, not like ochre", which means that healthy red should be wrapped in cinnabar like white cloth, and healthy white should be as shiny as goose feathers, but not as dim as salt, which means that green should be bright and moist, but not as blue. The yellow skin should be like a thin satin wrapped in realgar, and the white inside is yellow, not yellow like loess, which means "black desire is like heavy paint, not like the sky." Healthy black should be like shiny black paint painted layer by layer, not like black charcoal.

In addition to the main color of the face, there are guest colors, which refer to the facial changes caused by climate, diet, emotional changes, sports, work environment and so on. For example, the face will turn red after exercise, pale in cold winter, and dark after working outdoors for a long time. These also belong to the normal category.

Judging by the standard of "red, yellow and light, implicit and bright", not many people can have a healthy face now. People's work pressure increases and their lives become more and more irregular. Staying up late, eating high-sugar and high-fat foods, smoking and drinking, all of which can be shown on their faces.

There are five diseases on the face.

After talking about the main color and the guest color, the most common one is the sick color. When people are in poor health, they will appear sick. White, yellow, red, black and blue in the diseased colors all correspond to different physical diseases.

White and pale, white and pale. These whites have no luster and are not mixed with blood. It's all white that people use to describe sick faces. Chinese medicine believes that this whiteness is closely related to qi deficiency and blood deficiency. If qi and blood are insufficient to nourish the face, then the operation and generation of weak blood depends on qi. Chinese medicine says that qi can produce blood. If qi is deficient, the function of producing blood will decline, and blood can't nourish the face, so it will appear pale. There is also a kind of whiteness caused by body cold, and such people especially need to keep warm.
