Capsella bursa pastoris (Cruciferae)

SHEPHERD'S PURSE, MOTHER'S HEART, STRANGURY

A traditional medicine for stopping bleeding, shepherd's purse is still given by herbalists for many forms of bleeding, both internal and external, as well as for urinary tract problems. Its pale-green hairy leaves are used to make an infusion or tincture.

The distinctive heart-shaped fruit of C. bursa pastoris resemble the purses that people in medieval Europe used to hang from their belts, hence the common name of shepherd's purse. Native to Europe, it has spread to all temperate parts of the world, and has long been popular in traditional medicine for stopping bleeding. It is a low-growing annual herb with irregular, pale green, hairy leaves, and inconspicuous white flowers throughout the year.
