Abstract
Veno-occlusive disease was diagnosed in an 18-month-old boy who had regularly consumed a herbal tea mixture since the 3rd month of life. The boy developed portal hypertension with severe ascites. Histology of the liver showed centrilobular sinusoidal congestion with perivenular bleeding and parenchymal necrosis without cirrhosis. The tea contained peppermint and what the mother thought was coltsfoot (Tussilago farfara). The parents believed the tea aided the healthy development of their child. Pharmacological analysis of the tea compounds revealed high amounts of pyrrolizidine alkaloids. Seneciphylline and the corresponding N-oxide were identified as the major components by thin-layer chromatography, mass spectrometry and NMR spectroscopy. We calculated that the child had consumed at least 60 μg/kg body weight per day of the toxic pyrrolizidine alkaloid mixture over 15 months. Macroscopic and microscopic analysis of the leaf material indicated thatAdenostyles alliariae (Alpendost) had been erroneously gathered by the parents in place of coltsfoot. The two plants can easily be confused especially after the flowering period. The child was given conservative treatment only and recovered completely within 2 months.
