Dysentery, also known as intestinal dysentery and stagnation in ancient times, is one of the acute intestinal infectious diseases. The main clinical symptoms are fever, abdominal pain, tenesmus, and bloody stools. If infected with epidemic toxins, the disease will develop rapidly, accompanied by sudden high fever, coma, and convulsions, which is epidemic toxin dysentery. At the onset of dysentery, abdominal pain is seen first, followed by diarrhea, ranging from several times to dozens of times a day and night. It often occurs in summer and autumn, caused by damp heat evil, which injures the spleen and stomach, causing the spleen to lose its healthy function, the stomach to lose its digestive function, and stagnation, brewing in the intestines.
