Tinea pedis and tinea cruris are common and frequent diseases in dermatology and can account for more than 20% of dermatology outpatients, with a high recurrence rate. It is especially prevalent in workers who work in humid environments. The disease is recurrent throughout the year. Patients have blisters and peeling skin on the palms and soles of the feet in summer, and dry, cracked and painful hands and feet in winter, which seriously affects life, labor and production. Western medicine treatment, mainly antifungal drugs, the main drugs are clotrimazole, miconazole, econazole and bifenoconazole (such as Dakine, Mec, Dink, etc.). However, with the large number of clinical applications, the phenomenon of drug resistance has gradually increased, coupled with the limitations of toxic side effects, the treatment of fungal infections still faces many challenges. Numerous patients who are ineffective after using western drugs are seen in outpatient clinics. Chinese medicine believes that this disease is mostly caused by external dampness and heat, which accumulates in the skin or is caused by poisonous evil. Long-term dampness and heat turn into dryness, and the skin loses its glory and nourishment, resulting in thick, dry and cracked skin, shaped like a goose’s palm, so called “goose palm wind” and “foot disease”. After a long period of experience with external treatment, we have created a unique winter and summer treatment method for tinea capitis, which has been used in clinical treatment and has achieved very satisfactory results. The medicine is mainly based on the main medicine of the earth thorn bark and the hundred parts, together with herbs that dispel wind and dampness, kill insects and relieve itching, and astringent and detoxification, and the active ingredients of the medicine are extracted by the method of vinegar. This method is efficient, safe and inexpensive. For serious patients, good results can be achieved by combining with the internal consumption of Chinese herbs such as clearing heat and detoxifying.
