Plants containing high concentrations of selenium (Se)
have long been recognized for their toxic effects on
animals. Marco Polo, traveling in China in 1295, was
probably describing signs of Se poisoning when he wrote that
the hooves of his livestock became swollen and dropped off
when they grazed plants growing in certain areas (Rosenfeld
and Beath 1964). Loss of hair and nails in humans,
presumably suffering from chronic Se ingestion was described
in Colombia by Father Simon Pedro in 1560 [National Research
Council (NRC) 1976, 1983]. Guang-Qi (1987) has also
described and illustrated chronic selenium toxicosis in some
Chinese people
