RemarksThe leaves of Tussilago farfara L. ( Jap. name: Fukitampopo), which directly grow from the root are called Kuandongye, and the root of it is called Kuandonggen. They are used as antitussive and expectorant, as well as Kuandonghua. Fukitampopo is well distributed in the continent of Eurasia. The leaves are called Farfarae Folium in Europe and are applied to relieve coughs such as bronchial catarrh. Long ago, Dioscorides said "If you put the beaten leaves on rubors on the skin, erysipelas and all the other inflammatory regions, they will be cured. It will cure the people who are orthopneic because of dry cough or other transient reasons, if they fumigate dried leaves and inhale the smoke through a pipe. The smoke also induces expectoration of abscess in the lung. The fumigated smoke of the roots has the same benefits. If a pregnant woman drinks the brewed roots with honey water, she will abort a dead fetus." Since then, these benefits have been handed down.
Wakantōka, Japanese Kuandonghua, is the flos of Petasites japonicus (Sieb. et. Zucc.) Maxim., butterbur of family Compositae. Generally, it is sold as Fukinotō and is also used to alleviate cough and remove phlegm.
