Echium plantagineum, commonly known as purple viper's-bugloss, Paterson's curse or Salvation Jane, is a species of the genus Echium native to western and southern Europe, northern Africa, and southwestern Asia. It has also been introduced to Australia, South Africa, and United States, where it is an invasive weed. Due to a high concentration of pyrrolizidine alkaloids, it is poisonous to grazing livestock, especially those with simple digestive systems, such as horses.
E. plantagineum – commonly called Paterson's curse or pyrrolizidinosis in veterinary medicine – contains pyrrolizidine alkaloids, which is poisonous to grazing animals, especially nonruminants. When eaten in large quantities, it causes reduced livestock weight, and death in severe cases, due to liver damage. Paterson's curse can kill horses, and irritate the udders of dairy cows and the skin of humans. After the 2003 Canberra bushfires, a large bloom of the plant occurred on the burned land, and many horses became ill and died from grazing on it. Because the alkaloids can also be found in the nectar of Paterson's curse, the honey made from it should be blended with other honeys to dilute the toxins.
Also recorded as Lady Campbell-weed, Paterson's-curse, Purple Bugloss, Riverina bluebell, Salvation Jane and blue echium.
