ar-Turmerone is widely studied for its potential neuroprotective effects, particularly in relation to brain health and neurodegenerative diseases. It has shown promise in stimulating neural stem cell proliferation, which may support brain regeneration and repair, making it a subject of interest in research on conditions like Alzheimer's disease and stroke recovery. Its anti-inflammatory and antioxidant properties contribute to its ability to reduce neuroinflammation and oxidative stress in the brain.

In traditional medicine, ar-turmerone is valued for its role in supporting cognitive function and mental clarity. It is also being explored for its anticancer potential, especially in inhibiting the growth of certain tumor cells, including those in breast and colon cancers, by inducing apoptosis and suppressing cell proliferation.

Additionally, ar-turmerone exhibits antimicrobial activity against various pathogens, suggesting possible use in natural antimicrobial formulations. Due to its presence in turmeric essential oil, it is used in aromatherapy and natural health products aimed at reducing inflammation and promoting overall wellness.
