Facial color can be said to be the thermometer of health, which can reflect the health condition of human body. The Yellow Emperor’s Classic of Internal Medicine describes a healthy face as “white silk wrapped in vermilion”, that is, it looks like white silk wrapped in vermilion, white and red; while unhealthy people often show a variety of abnormal face color, such as pale, flushed, greenish purple, yellow, black, etc. Pale face: Chinese medicine considers most of them to be deficiency evidence, cold evidence or blood loss. Poor respiratory system will be pale; long-standing illness, hemorrhage, chronic nephritis, etc. will also make the face pale; people with a tendency to anemia, because of insufficient blood pigment will make the face white and shriveled color.

Cyanosis: Mostly due to Qi and blood obstruction and blockage of blood vessels. Heart failure, congenital heart disease, liver disease resulting in excessive waste in the blood, etc., will turn the face blue. Yellow face: Chinese medicine believes that yellow distinct belongs to damp-heat, yellow obscure mostly belongs to cold-damp; yellow face is shriveled, mostly due to weakness of heart and spleen, insufficient blood; yellow puffy face is spleen deficiency with dampness.
