洁古云∶ 疹之病， 肿于外者，属少阳相火也，谓之 。小红靥隐于皮肤中
者，属少阴君火也，谓之疹。 疹并出，则小儿难禁，然首尾俱不可下，大抵安里
药多，发表药少，小便秘则微疏之，身温者顺，身凉者逆，大忌外敷寒凉，内用疏
导，无此二者，可保无虞。

Jieguo stated: Regarding the disease of zhen (rash), if swelling manifests externally, it belongs to Shaoyang Xianghuo (Ministerial Fire of Shaoyang) and is called [missing character]. If small red macules are hidden within the skin, it belongs to Shaoyin Junhuo (Imperial Fire of Shaoyin) and is called zhen (rash). If both sha and zhen erupt simultaneously, the child may find it difficult to endure. However, purgative methods should not be used at either the beginning or the end of the illness. Generally, more medications for stabilizing the interior should be used, while fewer medications for releasing the exterior should be employed. If urination is obstructed, mild diuresis should be applied. A warm body indicates a favorable prognosis (shun), while a cold body indicates an unfavorable prognosis (ni). It is strictly forbidden to apply external cooling compresses or internally use draining and guiding agents. Without these two errors, safety can be ensured.
