Treatment for hookworm dermatitis: Take 30-60g of dried clove flowers and Polygonum thunbergii (or 250-500g of fresh herbs), add an appropriate amount of water, boil for 15 minutes, pour out the medicinal liquid, first steam the affected area while hot, and use a clean cloth dipped in the medicinal liquid for local hot compress. When the medicinal liquid is slightly cold, immerse the affected limb in the liquid. Each fumigation and washing session should last no less than 1 hour. To enhance the fumigation and washing effect, the medicinal liquid can be reheated repeatedly or the medicine basin can be placed on a charcoal stove for heating.
