PULLMAN, Wash. — Researchers at Washington State University have found that a combined extract of turmeric and ginger can significantly improve outcomes for bone implant patients — offering a potential breakthrough for the millions of Americans living with hip, knee, spinal, and shoulder replacements.
The new study, published in the Journal of American Ceramic Society, tested whether a coating made from ginger and curcumin — the active compound in turmeric — applied to titanium implants could address three of the most serious problems in orthopedic medicine: poor bone bonding, surface infections, and residual cancer cells following bone cancer treatment.
The results were striking. In animal testing, the extract roughly doubled bone bonding around the implant site within six weeks. It also eliminated 92% of bacteria found on implant surfaces — a major concern, since infections account for nearly a third of implant failures and often require complete removal of the device. Additionally, the extract reduced osteosarcoma cancer cells by eleven times compared to untreated controls.
Bose described the approach as marrying ancient wisdom with modern technology. "The best part is from the food, and the latest aspect comes from the biomedical device," she said.
With approximately 7 million Americans currently living with metal joint replacements, failed implants represent an enormous medical and financial burden. Bose and fellow researcher Amit Bandyopadhyay — Boeing Distinguished Professor in the same department — have spent years exploring how natural compounds can be integrated into modern biomedical devices, building on their earlier work using 3D printing to manufacture bone implants.
Bandyopadhyay described the goal as targeting multiple challenges at once. "We are making an implant that will offer some infection resistance. We are making an implant that can help with bone bonding," he said. "That's really the holy grail of it."
Turmeric and ginger have been used in traditional medicine across China and India for thousands of years. Bose says the compounds' well-documented anti-inflammatory and antioxidant properties make them attractive candidates for everyday preventative care, not just clinical applications.
