For the treatment of tinea pedis, topical drugs can be selected mainly according to the skin lesions, such as compound jinqiansong tincture, compound salicylic acid tincture, dyclonine, bifonazole cream, clotrimazole cream, etc. If you have mild erosion, you can apply dyclonine and other creams first, and then add exfoliating drugs such as compound jinqiansong tincture after the erosion is cured. If erosion is obvious and exudation is more, it can be soaked in 10% Sophora flavescens or Cortex Phellodendri solution, or soaked in 3% ~ 4% boric acid solution and 1: 5000 potassium permanganate solution. If pustules appear due to bacterial infection, external preparations of antibacterial drugs should be added.
