(Also known as "Tang")
"Tang" refers to the condition where water and feces jointly move towards the large intestine. The Spleen is responsible for transporting and transforming fluids for the Stomach; when Spleen Qi is weak and fails to distribute fluids properly, both fluids and waste products will flow down together through the anus. This corresponds to what is stated in *Jin Gui Yao Lue*: "When Spleen Qi declines, Tang (loose stool) occurs." Additionally, cold pathogen residing in the lower jiao can also cause water and feces to mix and pass down, often with a bluish-black color; this is referred to as "Cold in the Large Intestine causing Tang."
Luo Qianfu stated: "Tang" describes stools that are watery but contain small amounts of formed feces.

[Guizhi Tang (Cinnamon Twig Decoction)]

Symptoms include abdominal pain, spontaneous sweating, irritability and thirst, greasy complexion, rapid or deficient pulse, burning pain in the anus, stools resembling hot water, or accompanied by vomiting and severe colicky pain in the heart and abdomen, which are signs of Huoluan (Cholera-like syndrome).
