Most coughs and colds are caused by air conditioning or heat stroke. Anti-cold medicine can be chosen from patchouli or patchouli soft capsule. In case of cough, you can use carboxymethylstilbestrol oral liquid, snake bile and Sichuan shellfish liquid, strong loquat cream, etc. While using medications, you should pay attention to hydration and drink at least 2000-3000ml of water every day, and also eat more vegetables and fruits as appropriate. These foods are rich in vitamin C and contain more water to replenish the body’s vitamin C needs and improve the body’s ability to fight diseases. During the treatment period, it is important to take more rest and keep warm. Avoid excessive exertion, pay attention to emotional regulation, avoid tension and agitation.
