Toxic Principle. This plant does not appear to have been closely studied from the toxicological point of view; contrary to the statements generally made in the literature Van Rijn remarks that this species does not contain the doubtfully classed Euonymin.
Symptoms. Ingestion of the plant induces symptoms and lesions such as are due to violent vegetable purgatives.

RHAMNACEÆ.
Buckthorn (Rhamnus Catharticus L.) and (R. Frangula L.). The berries of both species are toxic and purgative, but both are uncommon and rarely eaten by stock.
Toxic Principle. The berries and bark contain the glucosides Frangulin (C21H20O9) and Rhamnetin (C16H12O7).
Symptoms. The berries are purgative, and there is some danger from large quantities, which may induce superpurgation. The leaves are astringent and may arrest milk secretion (Cornevin). Müller states that the inflammation of the stomach and intestines may terminate fatally.
