Kakadu Plum / Gubinge

Kakadu Plum holds the world record for natural vitamin C content — up to 5,300 mg per 100 g of fresh fruit, making it 100 times more vitamin C-dense than oranges and nearly twice that of camu camu. Used for over 40,000 years by Aboriginal Australians as a bush food and medicine, the fruit contains punicalin, punicalagin, and ellagic acid — ellagitannins with documented anti-proliferative and anti-angiogenic activity against colon, breast, and cervical cancer. Ellagic acid inhibits VEGF signalling, blocking tumour blood vessel formation, and induces apoptosis through the mitochondrial pathway. The Australian Institute of Sport has studied its antioxidant ORAC values, which are among the highest of any food. Aboriginal communities in the Kimberley and Northern Territory have traditional protocols for its use in treating wounds, infections, and illness — cancer-adjacent conditions in traditional diagnostic frameworks.
