风气挟带热邪，郁结于腠理，无法发散，发于皮肤，表现为不红不肿，仅有颗粒高起并伴有瘙痒的，称为痹症。
若在皮肤上略有形迹可见的，称为瘾疹。这些大都是风热所致，因郁结不散而形成。也有因为沐浴时受风，或者汗出后脱衣受凉而得的，这属于挟暑温邪，如果久治不退，必然发展为疮疹、丹毒等，病情由轻到重，这一点不可不知道。

For pruritus caused by stagnant heat generating wind, it is appropriate to employ methods of clearing heat, dispersing wind, and cooling blood; the therapeutic approach of Zhang Zihe (Zhang Congzheng) is exquisite. The *Classic of Medicine* (*Huangdi Neijing*) states: "All forms of itching are attributed to deficiency." The Lung governs Qi and is responsible for distributing it to the skin and hair follicles. If itching arises from the obstruction of Lung Qi, supplementation with herbs such as Fangfeng (Saposhnikovia Root), Renshen (Ginseng), [character missing in original text, likely a tonifying herb], and Baizhu (Atractylodes Macrocephala Rhizome) is indicated. If Wei Yang (Defensive Yang) is solidly closed at the Couli (interstices), leading to heat stagnation and disharmony of Wei Qi, manifesting as an excess pattern, formulas that regulate Qi, harmonize Blood, and dissipate stagnation should be used.
**Xuanshen Shengma Decoction**: Treats unbearable pruritus caused by wind affecting the skin.
Ingredients: Xuanshen (Scrophularia Root), Shengma (Cimicifuga Rhizome), Baizhu (Angelica Dahurica Root) (each 1 qian); Chantui (Cicada Slough), Fangfeng (Saposhnikovia Root), Gancao (Licorice Root), Huang [character missing, likely Huangqi/Astragalus] (each 0.7 qian). Add one cun length of Congbai (Green Onion Stem), decoct in water, and take orally.

Grind into fine powder. Take 2 qian with warm wine long after meals.
**Fangtong Tongsheng San**: Treats pruritus caused by wind on the skin. It is optimal to consume hot soup immediately after taking this medicine to induce sweating.
**Jiawei Buzhong Yiqi Tang**: Treats insufficiency of Middle Qi and unsmooth flow of Wei Qi, resulting in pruritus.
Ingredients: Renshen (Ginseng), Huang [character missing, likely Huangqi/Astragalus], Danggui (Angelica Sinensis Root), Baizhu (Atractylodes Macrocephala Rhizome) (each 1 qian); Chenpi (Tangerine Peel), Gancao (Licorice Root), Shengma (Cimicifuga Rhizome), Chaihu (Bupleurum Root), Fangfeng (Saposhnikovia Root), Baizhu (Angelica Dahurica Root), Chuanxiong (Ligusticum Chuanxiong Rhizome) (each 0.5 qian).

Use 3 liang per dose, decoct in one bucket of water, strain, and bathe several times until self-healed.

**Digang Qingteng Gao**: Take 3 spoons mixed with wine each time, administer before going to bed.
When wind qi carries heat and stagnates in the Couli (interstices) without being able to disperse, it manifests on the skin. If there is no redness or swelling, but only raised granules accompanied by itching, it is termed Bi (obstruction/numbness). If slight traces are visible on the skin, it is termed Yin Zhen (urticaria/hives). These are all caused by wind-heat stagnating and failing to disperse. Some cases arise from catching wind during bathing or exposure to cold after sweating, classified as carrying summer-heat warmth. If prolonged and unresolved, it must develop into sores, rashes, or erysipelas, progressing from mild to severe; this progression must not be ignored.
**Jiawei Qianghuo San**: Treats urticaria caused by external invasion of wind-cold-damp-heat attacking the skin and muscles.
