What herbs work for colitis?

Colitis belongs to the category of diarrhea in Chinese medicine, which is divided into two different types: violent diarrhea and prolonged diarrhea. Violent diarrhea can be treated with Huo Xiang Zheng Qi San and Ge Ge Gen Baicalin Lian Tang, while prolonged diarrhea can be treated with Painful Diarrhea Essentials Formula and Ginseng Ling Bai Zhu San.
Violent diarrhea may be caused by cold and dampness, dampness-heat obstruction (accumulation of dampness and heat to form stagnation), etc. Symptoms such as diarrhea, abdominal pain, headache, irritable heat, thirst, and limb pain may occur.
You can take Huo Xiang Zheng Qi San, which has the efficacy of aromatizing and transforming dampness, relieving the surface and dispersing cold (removing cold from the surface of the muscles); and take Ge Gen Scutellaria Lian Lian Tang, which has the efficacy of clearing away heat and drying dampness, and distributing the diarrhea and stopping the diarrhea.
Prolonged diarrhea may be caused by liver qi multiplying the spleen (excessive liver qi encroaching on the spleen), or weakness of the spleen and stomach, which may result in loose stools and diarrhea, a pale red tongue, and abdominal pain, etc. One can take Painful Diarrhea Essentials, which has the effect of suppressing the liver and supporting the spleen, and Ginseng Ling and Atractylodes Macrocephalae, which strengthens the spleen and strengthens qi, and resolves dampness to stop diarrhea.
Therefore, when diagnosed with diarrhea, it is recommended to consult a doctor in time for diagnosis and treatment, and choose the appropriate Chinese medicine according to the different types of evidence in order to play a better therapeutic effect.
