Contains the alkaloids nicotine and nor-nicotine and used by the Aborigines as an animal poison and at least to a limited degree, as a narcotic (though some records may refer to certain species of Nicotiana, also known as pituri). Toxic to horses, goats, sheep and camels. Plants thought to be hybrids with Grammosolen dixonii (F. Muell. & Tate)Haegi have been found near Berri and Renmark.
