(NY, Reuters Health, 5/23/05)

Dr. Anna Teresa Palamara of the Institute of Microbiology in Rome and team, report that resveratrol, a substance found in grapes, stopped influenza from replicating in cell cultures. The investigators found that the resveratrol had the most impact when introduced 3 hours after cells were exposed to influenza and no effect after 9 hours. In addition, when the researchers induced influenza in mice and then injected some of them with resveratrol, the survival rate of the animals rose by 40%, compared with mice injected with placebos, and there was 98% less virus present in the lungs of resveratrol-treated mice 6 days after infection.
