History & Folklore

This herb’s name derives from the appearance of the seed pods, which resemble heart-shaped purses. During the First World War, when the standard herbal medicines for staunching blood—goldenseal (Hydrastis canadensis) and ergot (Claviceps purpurea)—were unobtainable in Britain, shepherd’s purse was used as an alternative.

Medicinal Actions & Uses

One of the best remedies for preventing or arresting hemorrhage, shepherd’s purse has long been a specific treatment for heavy uterine bleeding. While weaker-acting in this respect than ergot, shepherd’s purse has none of ergot’s toxicity and is better tolerated by the body. It may be used for bleeding of all kinds—from nosebleeds to blood in the urine. An astringent herb, it disinfects the urinary tract in cases of cystitis, and is taken for diarrhea. It is used in Chinese medicine to treat dysentery and eye problems.

Research

Reports suggest that the plant is anti-inflammatory and reduces fever.
