Apocynum, commonly known as dogbane and Indian hemp, is a genus of the plant family of the Apocynaceae with seven species. Its name is from the Greek: apo, away and cyno, dog,[2] attributed to its toxicity. The genus is native to North America, temperate Asia (China, Siberia, Kazakhstan, etc.), and SE Europe (Italy, Bulgaria, Ukraine, etc.).[1][3][4]

Apocynum species are used as food plants by the larvae of some Lepidoptera species, including the mouse moth and the Queen butterfly.

Uses

Apocynum cannabinum was used as a source of fiber by Native Americans. Apocynum venetum (Chinese: 羅布麻) is used as an herbal tea in China.[5] Dogbane contains cymarin, a cardiotonic agent used to treat cardiac arrhythmia in humans.[6]
