..a South African acacia on the p.3 African List is Acacia karroo (Sweet Thorn)
Native to large parts of southern Africa (South Africa, Lesotho, Swaziland, Botswana, Namibia, Angola, Malawi, Mozambique, Zambia and Zimbabwe)..very common in its native range and is probably southern Africa's most common tree.
..it has become naturalised in Australia, northern Africa (i.e. Libya and Morocco), southern Europe (i.e. Spain, Portugal, Corsica and Sicily), South America (i.e. Bolivia and Chile), Iraq and Mauritius..
..A. karroo has many documented traditional medicinal uses including treating heart disorder, dizziness & dysentery..
it is said by Niazi in the Pharmaceutical Excipients blog to contain tryptamines..
it is often confused with the very similar Acacia horrida (Cape Gum, 'Dev-Babul') , which is native to Ethiopia, Somalia, Sudan, Kenya & Uganda..naturalized in India..it seems that the South African Acacia horrida var. transvaalensis (Burtt Davy) is synonymous with A. karroo..
A. horrida differs from A. karroo in pod shape and slightly greater number of flowers per inflorescence, and often larger number of pinnae pairs..it is also claimed without reference to be psychoactive and contain tryptamines..
as they are both very common species they are suited to phytochemical research over a wide geographical range..
other african species like A. senegal, A. nubica, A. tortillis (also middle-east) & A. albida (north africa & middle-east) have more solid/confirmed reports of containing DMT..
