Turmeric may help combat drug-resistant tuberculosis: New study

The humble turmeric, an essential ingredient in Indian curries, may help fight drug-resistant tuberculosis, a new study has claimed.

In Asia, turmeric is used to treat many health conditions and it has anti-inflammatory, antioxidant and perhaps even anticancer properties, researchers said. They found that by stimulating human immune cells called macrophages, a substance in Turmeric, curcumin, was able to successfully remove Mycobacterium tuberculosis, the causative bacterium of tuberculosis, from experimentally infected cells in culture.

The process relied on inhibiting the activation of a cellular molecule called nuclear factor-kappa B. "Our study has provided basic evidence that curcumin protects against Mycobacterium tuberculosis infection in human cells," said Dr Xiyuan Bai, from the University of Colorado, Denver.

The ability of curcumin to modulate the immune response to Mycobacterium tuberculosis points to a potential new tuberculosis treatment that would be less prone to the development of drug resistance. "The protective role of curcumin to fight drug-resistant tuberculosis still needs confirmation, but if validated, curcumin may become a novel treatment to modulate the host immune response to overcome drug-resistant tuberculosis," said Xiyuan, lead author of the study.

The study is published in the journal Respirology.
