Hot cold refers to wind-heat cold, which is a dialectic from the aspect of traditional Chinese medicine and can be used mainly to guide the use of Chinese medicine. It can be treated with Yin Qiao San plus or minus, or you can choose Chinese herbal medicines to clear the heat and detoxify the toxins, and the patient should drink appropriate water for hydration. The fever should be treated symptomatically at this time, and generally taking Chinese medicine directly is not able to bring down the elevated body temperature immediately. So this time you can choose western medicine, some anti-inflammatory drugs that relieve fever and analgesia, such as ibuprofen, acetaminophen or indomethacin can be chosen. In addition, after taking a sufficient amount of medication, the patient usually sweats and the body temperature drops to normal within 1-2 hours. Fever in the case of a hot cold is mainly dealt with from these two aspects.
