According to clinical pharmacology, mugwort has certain fungicidal effect, but the effect is very weak and not particularly good, so it is better to combine with other herbal medicines, such as white moss bark, bitter ginseng, scutellaria, yellow dock, rhubarb, zingiber officinale, etc., in clinical treatment, which can improve the antifungal effect of mugwort. However, in clinical practice for fungal infections such as foot fungus, herbal treatment is relatively single and the effect is very slow, so it is generally best to combine with antifungal western medicine for treatment. The western antifungal ointment is very commonly used, such as Dakine ointment, ketoconazole ointment, etc. The effect is very good. For foot fungus in addition to medication to keep the shoes dry and fresh, wear more breathable shoes and socks and wash your feet often.
