The dried nearly ripe fruit of Prunus mume (Rosaceae). Enters the Liver, Spleen, Lung, and Large Intestine channels. Sour, astringent, and neutral, it astringes the Lung to stop cough, binds the intestines to stop diarrhea, calms roundworms, and generates fluids. It is the key herb for roundworm reversal (hui jue), and Zhang Zhongjing's Wu Mei Wan uses it as chief for this condition.
