The dried capitulum of Inula japonica or I. britannica (Asteraceae). Enters the Lung, Spleen, Stomach, and Large Intestine channels. Bitter, pungent, salty, and warm, it excels at directing qi downward and dissolving phlegm. It is the key herb for phlegm-rheum accumulation with belching and vomiting. Zhang Zhongjing's Xuanfu Daizhe Tang pairs it with dai zhe shi for focal distention below the heart with persistent belching. Must be decocted wrapped in cloth.
