Pediatric wind disorder urticaria refers to a condition in children where the skin is tender and blood and qi are weak. It may occur because warm clothing causes the cou li (skin pores) to open loosely, or due to hot weather causing sweat to seep out, suddenly being invaded by wind pathogen. The wind pathogen contends with blood and qi, stagnating between the skin layers without dissipating, thus forming urticaria. These rashes grow connectedly, resembling slices of ginger root. Mild cases are called "wind macules" (Feng Ban), where the color does not change; severe cases are called "urticaria" (Yin Zhen), turning red-purple, accompanied by itching that cannot be relieved by scratching. Severe cases may even cause mental restlessness and confusion.
First, observe the color of the rash: If white, soak Achyranthes Bidentata Root (Niuxi) in wine overnight, bake until dry, and grind into powder. Take one qian or half a qian each time, mixed with warm wine. If red, grind kitchen hearth earth into fine powder, mix with ginger and honey water, and take one qian or half a qian.

Take one plant of Rumex Patientiae (Yangti Cai), including roots, leaves, branches, and stems, finely chopped. Decoct together until the leaves are soft. Pour into a basin. First, bathe the body with ordinary hot water to induce sweating. Then, rinse with the herbal decoction. Avoid wind after washing. Contraindicated: seafood and toxic fermented sauces.
