儿在母腹血热蒸，生后不免遇凉风，遍体发出如粟米，此名瘙疹何须评。
【注】瘙疹者，儿在胎中受母血热之气所蒸已久，及生后外遇凉风以致遍身红点，如
粟米之状。盈月内见者，名为烂衣疮；百日内见者，又名百日疮；未出痘疮之先见者，即
名为瘙疹。调摄谨慎，不治自愈。
痘后出疹盖痘传，余毒未尽夹食寒，遍身作痒如云片，加味消毒服即安。
【注】盖痘疹者，谓痘方愈而疹随发也。因痘后余毒未尽，更兼恣意饮食，外感风寒，
以致遍身出疹，色赤作痒，始如粟米，渐成云片。宜加味消毒饮疏风清热，疹即愈矣。
加味消毒饮

【方歌】盖痘疹因风热成，加味消毒饮最灵，荆防牛蒡升麻草，赤芍山楂连翘从。
心火灼肺风湿毒，隐隐疹点发皮肤，疏风散湿羌活散，继用消毒热尽除。
【注】瘾疹者，乃心火灼于肺金，又兼外受风湿而成也。发必多痒，色则红赤，隐隐
于皮肤之中，故名曰瘾疹。先用加减羌活散疏风散湿，继以加味消毒饮清热解毒。表里
清而疹愈矣。

The fetus is steamed by blood-heat in the womb; after birth, it inevitably encounters cool wind. Red spots like millet grains appear all over the body; this is named Saozhen (itching rash), requiring no further discussion.
[Note] Saozhen refers to the condition where the infant has been long steamed by the heat of the mother's blood during gestation, and upon birth, external exposure to cool wind causes red spots all over the body, resembling millet grains. Those appearing within one month are called Lanyi Chuang (rotten garment sore); those appearing within one hundred days are also known as Baitian Chuang (hundred-day sore); those appearing before the eruption of smallpox are simply named Saozhen. With careful nursing, it heals spontaneously without treatment.
Rash following smallpox is due to the transmission of smallpox pathogens, with residual toxins remaining and complicated by food stagnation and cold. The whole body itches like cloud patches; taking Jiawei Xiaodu Yin (Modified Detoxification Decoction) brings immediate relief.
[Note] Gaidouzhen refers to the situation where rashes erupt immediately after smallpox has just healed. This occurs because residual toxins from smallpox are not yet cleared, combined with excessive diet and external contraction of wind-cold, leading to rashes all over the body that are red and itchy, starting like millet grains and gradually forming cloud-like patches. It is suitable to use Jiawei Xiaodu Yin (Modified Detoxification Decoction) to disperse wind and clear heat, after which the rash will heal.

Heart fire scorches Lung metal, compounded by wind-damp toxicity; faint rash points emerge on the skin. Use Qianghuo San to disperse wind and dampness, followed by Xiaodu Yin to completely eliminate residual heat.
[Note] Yinzhen (urticaria/hive) is caused by heart fire scorching lung metal, combined with external contraction of wind-dampness. It must itch significantly, appears red, and lies faintly within the skin, hence named Yinzhen. First, use Jiajian Qianghuo San (Modified Qianghuo Powder) to disperse wind and dampness; subsequently, use Jiawei Xiaodu Yin (Modified Detoxification Decoction) to clear heat and detoxify. When the exterior and interior are purified, the rash heals.
