The first thing that is known as foot fungus is actually tinea pedis. It is caused by a fungal infection, a common inflammatory skin reaction, and Yunnan Baiyao is not used to treat fungal infections. Yunnan Baiyao is mainly used in clinical practice for patients with bruises and injuries, and it is known for its ability to invigorate blood and remove blood stasis. The most important thing to do is to go to a regular hospital and get antifungal treatment under the guidance of a doctor, rather than applying some so-called prescriptions on your own. Some of the commonly used clinical medications for tinea pedis are ketoconazole ointment, miconazole ointment, and terbinafine ointment. Of course, if the local exudation is serious, you can apply boric acid solution as a wet compress first. If the tinea pedis is severe and difficult to control, it can be treated orally with itraconazole and terbinafine.
