In the past, black root was used in medical practice as a means of soothing pain and relieving convulsions. The alkaloid cynoglossin has a curative-like effect, but, being a strong poison, has not found application.

There are indications that rats and mice do not tolerate the smell of this plant; basal leaves and stems with seeds collected in autumn, placed in a cellar where potatoes are stored, etc., have a beneficial effect in protecting them from rats. Rodents disappeared from these cellars, ceased to gnaw through wooden walls and dig passages in the ground. It is recommended to sow this plant near apiaries, and in the autumn to scatter the roots and stems with leaves in a lomshanik so that mice do not penetrate into the hives. Black root is planted in gardens to protect trees and flower beds from mice.
