Bush Medicine Leaves, Gloria Petyarre. The ‘Bush Medicine Plant’ refers to a species of Acacia, which is used as part of Indigenous traditional healing. Women collect leaves from this plant and boil them to extract the resin. The resin is then mixed with kangaroo fat, which results in a paste. This paste is used to heal bites, wounds, cuts and rashes and can also be used as an insect repellent.
