Flat warts are called “flat wart” in Chinese medicine, and there is no record of Gui Zhi Tang being able to treat flat warts. Gui Zhi Tang is a traditional Chinese medicine soup composed of Gui Zhi, Paeoniae Alba, Ginger, Licorice and Jujubes, which has the effect of detoxifying the muscles (removing the evil qi from the surface of the skin), sweating, and regulating the Ying and Wei (making the internal and external qi of the human body smooth, and each of them performs its own function). Gui Zhi Tang is mainly used to treat fever and malignant wind caused by external wind-cold, and is also useful for headache and strong neck, as well as treating nasal ringing, dryness and vomiting, etc. From the point of view of its efficacy and action, Gui Zhi Tang cannot treat “flat wart”. The adverse effects of Gui Zhi Tang are still uncertain, and it is contraindicated for those who are allergic to its ingredients. If you need to use the drug, should be guided by a Chinese doctor to identify the use, do not buy and use, so as not to delay the condition.
