小儿风疾瘾疹，是指小儿肌肤娇嫩，血气虚弱。有时因为穿着过暖导致腠理（皮肤毛孔）疏松开放，或者天气炎热汗液渗出，突然受到风邪侵袭，风邪与血气相搏结，滞留于皮肤之间，无法消散，从而形成瘾疹。这些疹子相连而生，形状像生姜片一样。轻的称为“风斑”，颜色不会改变；重的称为“瘾疹”，颜色变为赤紫色，发作时瘙痒，抓挠也不能缓解。严重的甚至会导致心神烦闷混乱。
首先观察疹子的色泽：如果是白色的，用牛膝酒浸泡一夜，焙干后研成粉末。每次服用一钱或半钱，用温酒调服。如果颜色是红色的，用灶底下的黄土研成细末，用生姜蜜水调服一钱或半钱。

治疗突然发作的风疹：用锻石不拘多少，和酸浆水调和后涂抹，随手即可消退。
治疗小儿瘾疹：如果不治疗，病邪入腹就能杀人。先用盐汤清洗，然后用蓼子捣烂敷在患处。又可以用枳壳锉成末，煎汤清洗。还可以用蚕砂二钱，水二碗，煮至一碗，用来清洗。

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.
