The Gumbi Gumbi Research Journey

Culture, Science, and the Healing Power of Gumbi Gumbi
In 2021, Uncle Steven Kemp and Yarbun Creations began a research partnership with Dr Mani Naiker from Central Queensland University (CQU). The goal was to study the medicinal properties of Gumbi Gumbi (Pittosporum angustifolium). This plant has long been used by Aboriginal people—especially the Ghungalu community—for its healing power.
Over the past three years, the team has worked to unite cultural knowledge with modern science. As a result, the research is creating new understanding around Gumbi Gumbi’s potential. Researchers are particularly interested in its applications for treating cancer, skin conditions, inflammation, and related health issues.
What the Research Has Revealed So Far
Initial tests were conducted by the Bioactive and Functional Foods Research Group at CQU. These studies focused on identifying both antioxidant and anti-cancer properties. In vitro (cell culture) testing showed several important outcomes:
High antioxidant levels in leaves and fruit
Cytotoxic activity against cancer cells in controlled settings
Early signs of potential for plant-based therapies
These findings support what Aboriginal Elders have known for generations. Gumbi Gumbi brings balance to the body and spirit. However, without human clinical trials, the Therapeutic Goods Administration (TGA) cannot yet recognise it as a registered treatment. Therefore, the next phase is vital.
Understanding the Plant Itself
Gumbi Gumbi grows across inland and southern Australia. It thrives in dry, sandy areas, especially near eucalyptus woodlands and water catchments. Locals often refer to it as Native Apricot or Cattle Bush.
Its red seeds are sticky and striking. The plant produces woody capsules that remain on the tree for several seasons. Furthermore, it is mostly dioecious, which means male and female plants grow separately. With thick bark and weeping branches, it can reach heights of 10 metres.


Where to From Here?
The next step includes clinical trials, product safety testing, and Good Manufacturing Practice (GMP) certification. These processes are necessary before the plant can be safely offered to the public.
However, this research is about more than science. It is also about honouring culture, protecting Indigenous intellectual property, and proving the truth of lived knowledge.
Importantly, it opens the door for ethical, culturally safe treatments. It ensures that future generations benefit from the healing already found in Country.
Traditional Healing Through Gumbi Gumbi
In the Ghungalu language, “Gumbi Gumbi” translates to “woman.” This reflects not only care, but strength and healing.
Across many Aboriginal Nations, the plant has supported wellness through:
Cancer symptom relief
Blood sugar regulation
Body and bowel detoxification
Emotional healing from anxiety or depression
Treatment of sores, rashes, and dandruff
Respiratory support during colds and flu
Relief from mastitis and inflammation
Each remedy was made with spiritual understanding, practical skill, and ancestral permission. As a result, these traditions remain strong.
