Comments

Emergency treatment: "Plants- pyrrolizidine alkaloids"; [HSDB] Poisonings from Senecio vulgaris L. have caused severe liver damage and failure; "In man, poisoning is manifested as acute veno-occlusive disease, leading to hepatomegaly, ascites, massive pleural effusion, and in many cases progressing to cirrhosis. Some metabolites are released into the circulation and are believed to pass beyond the liver to the lung causing vascular lesions. The pyrrolic metabolites are cytotoxic and act on the hepatocytes and on the endothelium of blood vessels of the liver and lung. From evidence in experimental animals and circumstantial evidence in one human case report, the possibility of toxic pulmonary disease in man cannot be ruled out." [Reference #1] "Symptoms of acute exposure to a mixture containing this compound include abdominal pain, hepatomegaly, emaciation, nausea, diarrhea and liver cirrhosis. Death occurred in several cases. Ingestion of mixtures in which this compound is a component has caused infant hepatic veno-occlusive disease and early death." [CAMEO]
