Chinese medicine generally classifies colds into three categories: wind-heat colds, wind-cold colds and summer-damp colds. Wind-heat colds, which are characterized by fever, yellow nasal discharge, coughing and spitting of thick yellow phlegm, generally fall under the category of wind-heat colds, and can be treated with medicines to clear the wind and heat, such as mulberry chrysanthemum drink or forsythia powder, which can relieve the signs of heat. In addition, you can also use fishy grass, mulberry leaf, chrysanthemum, infusion for self-treatment of heat, detoxification, and phlegm, often triggered by the external sensation of wind-heat. From Western medicine, the first thing to look at is whether there is a fever, whether there is an inflammatory reaction, especially when the coughing and spitting of phlegm is relatively large, to see whether it is a bacterial infection or a viral infection.
