Nitrate content in the raw edible portion of wild C.bursa-pastoris species was found very high at 2.5g/kg fresh weight (in the range of celery, 2.3g, and spinach, 2.7g).

Nitrite poisoning in pigs was suspected when 4 of 18 pigs died in case in South Africa. „The pigs showed typical brownish discolouration of the blood at autopsy. It was established that they ingested… Capsella bursa-pastoris contained nitrites [4630 ppm]. The drinking water and some of the other plants tested positive for nitrates but not for nitrites. This is the first report of suspected nitrite poisoning in pigs caused by Capsella bursa-pastoris.

„The herb [whole herb, Bursae pastoris herba] is traditionally used to stop bleeding and to treat heavy periods (menorrhagia), diarrhoea and cystitis. In chinese medicine it is used for unspecified eye diseases and dysentery… Despite animal studies showing anti-inflammatory , anti-ulcer, diuretic, hypotensive and other effects, the traditional uses of sheperd's burse are not well explained. It is thought that a peptide with oxytocin-like activity is responsible for the antihaemorrhagic action.“
