Indospicine is an amino acid not found in proteins, which occurs in Indigofera species. The chemical resembles arginine.

It is toxic to mammals and causes liver damage and abortion. Dogs are particularly sensitive to the toxic effect and can sicken or die after eating a grazing animal that has eaten Indigofera.^[1]^[2]
