[4] Breonadia salicina (Matumi, Afrikaans: Mingerhout, Sotho: Mohlomê, Venda: Mutu-lume, Zulu: Umfomfo) is a protected tree in South Africa.

The tree is generally found in subtropical to tropical climates, mainly in small populations in South Africa to Saudi Arabia and even Madagascar.

In one experiment, leaf extracts of Breonadia salicina helped prevent the growth of bacteria that cause food poisoning.

[10] Physical characteristics, such as diameter and density of xylem vessels, is due to the plant's genetic makeup, but also many environmental factors as well (for this experiment it was rainfall).

[10] Tannins are polyphenols that have been found to help with reducing growth of E. coli in digestive tracts.

[12] Leaf extracts of B. salicina have also been found to reduce activity of both gram-negative and gram-positive bacteria.
