Study: Turmeric and Ginger Extracts Help Bone Implants Fuse More Effectively

A new study from Washington State University suggests that extracts of turmeric and ginger can significantly improve the integration of bone implants, while also killing bacteria and cancer cells. This discovery could benefit millions of patients undergoing joint replacement surgery or treatment for bone cancer.

In preliminary experiments, the extract was found to nearly double the rate of bone growth around implants within six weeks. It also eliminated over 90% of bacteria on implant surfaces and significantly reduced the number of cancer cells. These findings combine elements of traditional natural medicine with modern biomedical technology.

Turmeric, a bright orange spice, and ginger root have been used for thousands of years in both culinary and medicinal practices in countries like China and India.

The study, published in the Journal of the American Ceramic Society, was conducted by researchers Bose and Amit Bandyopadhyay. Their work shows that compounds found in turmeric and ginger could become valuable additions to advanced medical treatments. The study builds on their earlier research into 3D-printed bone implants—a concept that was once considered futuristic but is now widely used in medicine.

In this study, scientists focused on common complications associated with bone implants. A significant number of implants must be replaced because they fail to properly fuse with bone or become unstable over time. In addition, infections on implant surfaces—often metallic—occur in nearly one-third of cases and are notoriously difficult to treat.

“In many cases, infections force doctors to remove the implant,” said Bose. “There are limited alternatives for stabilizing bone in such situations, so these complications can have serious medical and financial consequences.”

The extract was also tested on osteosarcoma cells, the most common type of bone cancer in children and young adults. Even after surgery, chemotherapy, and implantation, some cancer cells can remain in the body.

Researchers explored whether ginger extract and curcumin—the active compound in turmeric—could be applied to titanium implants and released gradually over time. The extract was tested both in laboratory conditions and in an animal study involving rat femur implants.

Results showed that the treated implants bonded much more effectively with bone, with approximately double the integration observed six weeks after surgery. The extract also destroyed 92% of bacteria on implant surfaces and reduced cancer cell presence around the implant by 11 times compared to untreated controls.

“This is a complex challenge,” said Bandyopadhyay. “We are developing implants that can resist infection to some extent while also strengthening the bond between bone and prosthetics—whether hip, knee, spine, or shoulder implants.”

Bose added that the antibacterial and anticancer effects of turmeric and ginger are just part of their broader health benefits. Both are known for their anti-inflammatory and antioxidant properties.

“I’m very excited about these natural compounds,” Bose said. “They could be easily used in everyday life as preventive agents. Curcumin has strong anti-inflammatory effects, and inflammation-related bone loss is a serious issue. Ginger may also have anticancer properties. These compounds have real preventive potential.”
