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.

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.
