Use in Treatment

Shepherd's purse has a long history of use for postpartum hemorrhoids and internal bleeding, notably during World War I when other hemostatic drugs were scarce. It is a mild remedy for excessive menstruation and can stop nosebleeds. Its antiseptic and diuretic properties make it effective for cystitis, while its anti-inflammatory and astringent qualities aid in reducing inflammation. A 1969 study confirmed its alkaloid stimulates uterine contractions, helping with painful menstruation.

Cultivation

Shepherd's purse thrives in poor soil, preferring sunny or lightly shaded areas.
