Researchers say that curcumin, a natural compound found in the spice turmeric, could help eliminate certain viruses. The scientists, from the Wuhan University of Engineering in China, published a study, “Antiviral and virucidal effects of curcumin on transmissible gastroenteritis virus in vitro,”in the Journal of General Virology which showed that curcumin can prevent transmissible gastroenteritis virus (TGEV), an alpha-group coronavirus that infects pigs, from infecting cells. At higher doses, the compound was also found to kill virus particles.
