Intoxication caused by Senecio spp is characterized by an irreversible damage of the liver cells due to the action of pyrrolizidine alkaloids present in these plants. They contain other groups of volatile components, such as terpenes, which may also be toxic. An aqueous extract obtained by water steam distillation of Senecio grisebachii fresh flowers was orally given to mice (0.5 mL/mouse/day) for 30 days. Animals were observed periodically. Weight loss, pale mucous membrane color, low body temperature and decreased capillary refill time were symptoms compatible with dehydration. Histopathological findings showed congestion and edema in small and large intestines. Liver showed hydropic and fatty degeneration with centrilobular necrosis. Res...
