Huo Xiang Zheng Qi Shui is a proprietary Chinese medicine that has the effect of relieving dampness, regulating Qi and harmonizing the middle. Huo Xiang Zheng Qi Shui is mainly used to treat wind-cold or summer-damp colds, as well as gastrointestinal colds, and is good for relieving symptoms such as dizziness, headache, nausea, vomiting, and upper abdominal fullness. Patchouli contains alcohol and therefore has some stimulating effects. It is generally not significantly effective for skin diseases such as prickly heat. It is also important to note that Huo Xiang Zheng Qi Shui should not be used at the same time as cephalosporins, metronidazole, ketoconazole, furazolidone and other drugs to avoid disulfiram reactions, which can lead to flushing, chest tightness, difficulty breathing and other allergic symptoms. Icariin may also cause rashes, itching and other adverse reactions.
