Many people have coughs and colds and choose random cough medicines to treat them, but some of them are cured and some of them are delayed. The reason is that there are different types of coughs, cold coughs, hot coughs, and of course other types of coughs. But most coughs can be divided into two types: cold cough and hot cough. How can you tell the difference? The sputum is white, thin, transparent or foamy for a cold cough; yellow and thick sputum or white sputum that is thick and sticky and not easy to get out is a hot cough. For cold cough, warm cough medicine must be used, and there are not many Chinese medicines such as Xiao Qing Long Combination, Xiao Qing Long Granules and other Chinese medicines for coughing. If the phlegm is white and easy to cough out, orange red phlegm cough liquid can also be used. If you have a hot cough, you need to use cool cough medicine, and there are many Chinese patent medicines such as acute syrup, ten flavors of gentian flower granules, snake bile and Sichuan shellfish liquid and so on. Only when the symptoms are right, the Chinese medicine can show good results.
