Antipyretic, antiemetic, expectorant, hemostatic
This herb is used for thick, yellow, hard-to-expectorate phlegm when there is respiratory
infection, and for vomiting caused by heat in the stomach, for which it can be combined with pinellia and coptis. It can also be used for morning sickness and a restless fetus when combined with scutellaria and pinellia.
Chinese herbalists also use this herb to cool blood heat for various symptoms of bleeding, such as hemoptysis (spitting up of blood and phlegm), hematemesis (vomiting blood), epistaxis (bloody nose), and metrorrhagia (menstrual flooding).
