　　(2) Candida balanitis: Baking soda solution can be used to clean the affected area, or imidazole ointments such as Daktarin ointment or clotrimazole ointment can be applied externally.
　　(3) Dandelion wash: Take 30g of dandelion, 30g of chrysanthemum, and 10g of, decoct them, and use the liquid to externally wash the affected area once daily, with each application lasting about 20 minutes.
