论曰伤寒后 疮者，因腹中有热，其人食少，胃中空虚，三虫须食或食五脏，或食下
部，隐僻有疮，故名 疮。其候齿无色，舌上尽白，四肢沉重，忽忽喜眠，甚则唇里有疮。
其疮在上唇里，如米粟。心内懊 痛者，此虫食五藏之证也。若下唇里有疮，其人喜眠者，
此虫食下部之证也。若肛烂见五脏者死。

Discourse states: Gan chuang (Gan sore/Gum disease caused by parasites) occurring after Shanghan (Cold Damage) arises because there is heat in the abdomen, the patient eats little, the stomach is empty and deficient, and the Three Worms (parasites such as roundworms, pinworms, and liver flukes) require food. They may gnaw on the Five Viscera or the lower part of the body, forming sores in hidden and obscure areas; hence it is named Gan chuang. The manifestations include teeth lacking luster, the entire tongue surface being white, heaviness in the four limbs, mental confusion with a tendency to sleep, and in severe cases, sores inside the lips. If the sores are located inside the upper lip, resembling millet grains, and accompanied by inner heart restlessness and pain, this indicates the syndrome of worms gnawing the Five Viscera. If sores appear inside the lower lip, and the patient prefers sleeping, this indicates the syndrome of worms gnawing the lower part. If the anus rots and reveals the form of the Five Viscera, it is a death syndrome.
