Traditional Chinese medicine treatment of inguinitis is mostly based on proprietary medicines. In the early stage of onychomycosis, if there is no obvious pain or abscess in the early stage, you can choose localized treatment with proprietary Chinese medicines. Common proprietary medicines for onychomycosis include ichthyol ointment and Jinhuang San, etc., which are used to activate blood circulation and remove blood stasis (to promote blood circulation and eliminate blood stasis in the body), and to reduce swelling and relieve pain (to eliminate swelling and pain). Skin irritation and allergic reactions are occasionally seen with ichthyolipid ointment. It is contraindicated for those who are allergic to the product, and should be used with caution in allergic individuals. The drug should not be used on broken skin. Avoid contact with eyes and other mucous membranes (e.g. mouth, nose, etc.). If there is burning sensation, redness and swelling at the site of application, the drug should be discontinued and the topical medication should be washed off, consult your physician if necessary. The adverse reactions and contraindications of Jin Huang San are not clear. Traditional Chinese medicine can have a certain therapeutic effect in the early stage of the disease, but if the furuncle infection develops further, it is necessary to combine with Western medical treatment, such as Western medicine treatment, surgical treatment, physical therapy and so on. The treatment of onychomycosis needs to be chosen according to the severity of the disease, and patients who use medication need to strictly follow the doctor’s instructions.
