Cockspur (Acacia cornigera)

186-365

Sometimes called the Bullhorn or Cow Thorn, this plant has a symbiotic relationship with an aggressive and painful species of ant (Pseudomyrmex ferruginea). The ants live in its thorns and protect the tree from encroaching plants, trying to grow near its trunk or leaves high in the canopy. The ants also emerge from the thorns to attack other insects, humans and animals that come in contact with the tree.
The Pseudomyrmex ferruginea ants have been used as a bush medicine for relief of mucous congestion in infants which are given water containing the ants (once they've been squeezed and strained). Snake doctors use the Cockspur bark and root to slow down snake venom from entering the bloodstream. Acne and other skin conditions can be treated by bathing in water in which the thorns have been boiled.
