Abstract

The invention relates to an antipruritic agent and a mosquito-repelling and itch-relieving patch. The antipruritic agent comprises, by weight, 1-10% of sodium polyacrylate, 0.05-2% of a crosslinking agent, 0.01-5% of an organic acid, 1-30% of a filler, 15-70% of a humectant, 1-30% of a solubilizer, 0.5-8% of an adhesive, 20-80% of water and 1-30% of plant essential oil. The antipruritic agent is applied to the first surface of a separation film (2), and is cured to form an antipruritic layer (1); a protective film (4) is pasted on the surface of the antipruritic layer (1); and a mosquito repelling drug is attached to the second surface of the separation film (2) to obtain the mosquito-repelling and itch-relieving patch.
