CQUniversity’s Breakthrough On Native Plant Medicine

A groundbreaking study by CQUniversity has revealed the promising antioxidant and cancer-fighting properties of Gumbi Gumbi (Pittosporum angustifolium), a native Australian plant used for generations in First Nations healthcare. This study, funded by the CQUniversity BHP Chair in Indigenous Engagement, showcases how modern science is backing up traditional medicine.
Led by Dr. Mani Naiker from the Bioactive and Functional Foods Research Group, the project was conducted in collaboration with Ghungalu Elder Uncle Steve Kemp. Uncle Steve provided Gumbi Gumbi samples from across Ghungalu Traditional Lands in Woorabinda, a key part of the research. The results, presented at a CQUniversity workshop in June 2024, highlighted the chemical makeup of Gumbi Gumbi leaves and fruit, showcasing potent antioxidants and promising cytotoxicity against cancer cells.
For Uncle Steve, Gumbi Gumbi has been a lifelong part of his culture and heritage. “I first learned about the plant from my father. These findings are going to benefit everyone: people who could use these treatments, and the community at Woorabinda, knowing this knowledge comes from our People,” Uncle Steve shared.
Traditionally used to treat a range of ailments, from cancer and high blood pressure to diabetes and dandruff, Gumbi Gumbi has long been regarded for its medicinal qualities by Indigenous Australians. Now, thanks to CQUniversity’s research, the plant’s potential for wider medical use is gaining attention.
Dr. Naiker explained that CQUniversity’s new native plant hub, based at the Central Queensland Innovation and Research Precinct, is continuing research into the benefits of Gumbi Gumbi. Future clinical trials will explore its cancer-fighting potential, alongside ongoing analysis of sugar content and glycaemic response for potential natural blood sugar control.
The research also delves into how the plant's potency is affected by factors such as harvest time and drying methods. "This study brings both scientific validation and commercial potential to Gumbi Gumbi and other native foods," said Dr. Naiker.
The workshop attracted growers, investors, and locals interested in Indigenous plant resources, underscoring the potential for these native foods to benefit not only First Nations communities but the broader Australian population as well.
CQUniversity researchers are also investigating other native plants, including Australian ginger and Burdekin plums, further advancing knowledge on the commercial and health benefits of native Australian flora.
