Bitter milkwort is a plant. The flowering plant and root are used to make medicine.
People take bitter milkwort for airway disorders, cough, and bronchitis, but there is no good scientific evidence to support these uses.
Don't confuse bitter milkwort (Polygala amara) with asarabacca (Asarum europaeum) or senega (Polygala senega). All three plants are sometimes called snakeroot.
Coronavirus disease 2019 (COVID-19): Some experts warn that bitter milkwort may interfere with the body's response against COVID-19. There is no strong data to support this warning. But there is also no good data to support using bitter milkwort for COVID-19.
