Herbaceous perennial in the daisy family, originating from damp low lying meadows and stream edges throughout Europe, robust and easy to grow in garden situations as long as they are kept well watered through hot summers. Hemp agrimony has been used medicinally as a detoxifying herb for fevers, colds, flu and other viral conditions. It also stimulates the removal of waste products via the kidneys. Due to its content of alkaloids, the plant should only be used under professional supervision. The leaves and flowering tops are alterative, cholagogue, depurative, diuretic, emetic, expectorant, febrifuge, purgative and tonic. The plant has a long history of use as a gentle laxative that does not provoke irritation, though excessive doses cause purging and vomiting. A tea made from the dried leaves will give prompt relief if taken at the onset of influenza.
In China E. fortunei (Pei Lan) is used in TCM, and can be used interchangeably with E. cannabinum.
