The Kakadu Plum—also known as gubinge, billygoat plum, or Terminalia ferdinandiana—was recognized for its health benefits long before modern science caught on. Indigenous Australians have utilized this remarkable fruit for thousands of years as a traditional medicine to treat colds, flu, headaches, and infections, as well as an antiseptic for wounds.

What’s fascinating is that modern research has validated these traditional uses. The Kakadu Plum is now celebrated as the world’s richest natural source of vitamin C, containing over 3,000% of the daily value in just 100 grams. It’s also packed with antioxidants, dietary fiber, copper, and iron, making it a true superfood.

While it might seem like a recent discovery in the wellness world, Indigenous knowledge had already unlocked its potential centuries ago.

The Kakadu Plum is not only a cultural treasure but also a medicinal powerhouse, both in traditional and modern contexts.
