Six out of 6 steers survived a lethal dose of Moraea polystachya (blue tulp) when treated with activated charcoal alone and 3 out of 4 wethers survived when treated with activated charcoal plus potassium chloride. Barbeque charcoal was not of therapeutic value. An increase in the level of serum potassium served as indicator of acute poisoning in only a third of the animals.
