Terminalia ferdinandiana, also called the gubinge, billygoat plum, Kakadu plum or murunga, is a flowering plant native to Australia.
Its vitamin C concentration may be as high as 1000–5300 mg/100g
That’s 55 Xs the vitamin C than oranges!
It was used as a traditional medicine for the treatment of numerous ailments. The fruits were eaten by Australian Aborigines on long treks or hunting trips and were considered more valuable as a medicine rather than as a food. The inner bark of the tree was used to treat a variety of skin disorders and infections including wounds, sores and boils.
Together, with other antioxidants (like vitamin e and lutein), minerals (like zinc and iron to name a few!), bioactivs and gallic and ellagic acids (which have antibacterial, anti-inflammatory and antifungal properties), it’s no surprise many brands have included it as a key ingredient in their products.
