Characteristics
R. flam. has produced gangrene of the arm down to tendons and bone, in the case of a female, from applying the plant to the wrist. It produces in horses who eat much of it distension of abdomen, and inflammation and gangrene of abdominal organs. But (according to Dic. des Sc. Méd., quoted by Jahr) it is only hurtful to horses if eaten in excess; it promotes digestion when eaten moderately.
