Turmeric and rhubarb contain natural compounds that may help fight antibiotic-resistant bacteria, according to new research.1

Antibiotic-resistant bacteria are germs that have evolved to survive the drugs designed to kill them, making certain infections harder to treat. Antibiotic resistance is a major and growing global public health threat.2

Turmeric and Rhubarb Compounds Show Promise Against Resistant Bacteria

Researchers at Utah State University identified nine multidrug-resistant bacteria in wastewater. Some of them could pass their resistance genes to more dangerous germs, raising concerns about the potential development of highly drug-resistant superbugs.

To explore ways to stop these bacteria from spreading, the researchers tested different natural compounds. Curcumin, a compound in turmeric, and emodin, from rhubarb, were the most effective at slowing cell growth and preventing the formation of biofilm—a bacterial community.1
