Huo Xiang Zheng Qi Shui and cold medicine will not conflict, so you can always take cold medicine by mouth after drinking Huo Xiang Zheng Qi Shui, and there will be no conflict as well as adverse reactions due to the combination of medicines. Since Huo Xiang Zheng Qi Shui contains ethanol, this drug should be avoided together with antibiotics, especially cephalosporins. If Huo Xiang Zheng Shui is used followed by cephalosporin, it can lead to disulfiram-like reactions that can be life-threatening in severe cases, so it must be taken seriously. If you take patchouli together with cold medicine, it is most likely that the patient has a gastrointestinal cold, and the diet should be light at this time, and it is best to have a liquid diet, and then gradually increase other diets after the disease has recovered.
