For the treatment of wind-cold cold, to analyze the specific problem. It is generally divided into two kinds of cases: the first one, table solid evidence, that is to say, people with strong physique have a cold, usually with malignant wind-cold fever, no sweat, floating and tight pulse, focusing on those who have no sweat although they sometimes have a fever and are afraid of coldness around the body, at this time, ephedra soup can be applied to treat it. This is a formula from Zhang Zhongjing’s Treatise on Typhoid Fever, which consists of four herbs: ephedra, cinnamon sticks, almonds and licorice. If the wind-cold is mild, it can be taken with ginger and brown sugar water or ginger and jujube water, and at the same time drink more hot porridge, and cover up and avoid wind-cold, this kind of cold will be cured by sweating. The second kind, the physical weakness of the person, that is, the surface of the virtual evidence. This is characterized by a malignant wind-cold and fever, but with sweating and a slow floating pulse. The difference between this and the cold of the Epiphenomenon is that there is sweating, and the conscious body is always sweaty and jittery. At this time, the same formula of Zhang Zhongjing, Gui Zhi Tang is used to harmonize Ying and Wei. This formula consists of Gui Zhi, red peony, ginger, jujube, and licorice, and after taking it, it is also necessary to cover up the clothes and blankets, drink hot porridge, and take shelter from the wind and cold.
