If it is a viral cold, the Western medicine approach is to take medication to suppress the high fever. Even if the fever subsides, the virus may become resistant to the medication, and people will feel weak for a while. Chinese people should use traditional Chinese medicine methods to find an outlet for body temperature. Bloodletting therapy and acupuncture are too difficult without a professional. Gua sha in the area of the Dazhui point can help reduce fever; any hard object can be used to scrape a bit. If you are really worried, you can let your elder sister rub that area for you; rubbing until it turns red is also effective! 😀😀😀
