Leaves, flowers.

Constituents

The herb contains cheiranthin and other cardioactive glycosides.

History & Folklore

In 1735, the Irish herbalist K’Eogh described wallflower thus: “It provokes urination and menstruation and expels a stillborn child, and the afterbirth if a decoction of the dried flowers or a little seed is drunk in wine.”

Medicinal Actions & Uses

Although wallflower was formerly used as a diuretic, there was no understanding of its powerful effect on the heart. In small doses it is cardiotonic, supporting a failing heart in a manner similar to foxglove (Digitalis purpurea). In more than small doses it is toxic, and is therefore rarely used in herbal medicine.

Cautions

Use only under professional supervision. Do not take during pregnancy.
