Shepherds purse is little used in medical herbalism, though it is a commonly used domestic remedy, being especially efficacious in the treatment of both internal and external bleeding, diarrhoea etc. Shepherds Purse Tea made from the whole plant is antiscorbutic, astringent, diuretic, emmenagogue, haemostatic, hypotensive, oxytocic, stimulant, vasoconstrictor, vasodilator and vulnerary. A tea made from the dried herb is considered to be a sovereign remedy against haemorrhages of all kinds – the stomach, the lungs, the uterus and more especially the kidneys.  Clinical trials on the effectiveness of this plant as a wound herb have been inconclusive. It appears that either it varies considerably in its effectiveness from batch to batch, or perhaps a white fungus that is often found on the plant contains the medically active properties. The plant has been ranked 7th amongst 250 potential anti-fertility plants in China. It has proven uterine-contracting properties and is traditionally used during childbirth. The plant is a folk remedy for cancer – it contains fumaric acid which has markedly reduced growth and viability of Ehrlich tumour in mice. A homeopathic remedy is made from the fresh plant. It is used in the treatment of nose bleeds and urinary calculus. The German Commission E Monographs, a therapeutic guide to herbal medicine, approve Capsella bursa-pastoris Shepherds Purse for nose bleeds, premenstrual syndrome, wounds & burns.
