Australian bush plum (Terminalia ferdinandiana) (fruit)

Australian bush plum, or Kakadu plum, is the fruit of a small deciduous tree, Terminalia ferdinandiana, found in northwestern Australia. Kakadu plums have been a food and medicinal source for aboriginal people for thousands of years 1. With an average vitamin C content of 3.0%–3.5% (range = 0.2%–5.9%), the bush plum is believed to be the single natural food source with the highest vitamin C content in the world 2. The U.S. Food and Drug Administration accepted the Australian bush plum as a New Dietary Ingredient (NDI) in 2005.
