When a baby has a fever, if the fever is caused by a cold or a fever caused by a digestive disorder such as nausea or vomiting, it is possible to use patchouli water for treatment. But Huo Xiang Zheng Qi water does not have the function of treating fever, nor does it have the function of reducing fever. It can only treat the symptoms of cold, such as headache, faint weight or abdominal distension and fullness, vomiting, diarrhea, and gastrointestinal type of cold, and the effect of using Huo Xiang Zheng Qi water is better. If the fever is caused by other reasons or simply a fever, it is not recommended to give your baby patchouli water for treatment. You need to measure your child’s body temperature, and if the temperature exceeds 38.5 degrees, you must take oral ibuprofen suspension or acetaminophen suspension for fever reduction. If the temperature of fever is not too high, below 38.5 degrees, you can use pediatric black beetle and clear fever granules, pediatric antelope granules or pediatric cold and flu clear fever granules to reduce fever.
