Drinking American Ginseng Tea May Rapidly Protect Your DNA, Study Finds

Views 2915

A single cup of American ginseng tea may be enough to shield your DNA from oxidative damage in as little as two hours, according to a new pilot study.1 This intriguing finding highlights the powerful genoprotective potential of this time-honored herbal beverage.

In the study, 14 healthy individuals were randomly assigned to drink either 200 mL of freshly brewed American ginseng tea or plain water. Blood samples taken before and 2 hours after consumption were exposed to UVB radiation to induce oxidative stress. Using the comet assay, researchers assessed the degree of DNA damage.1

Remarkably, the ginseng tea group experienced a statistically significant 17% reduction in DNA damage just 2 hours post-consumption, while no change occurred in the water group. As the study authors noted, "The current study demonstrated a cup of American ginseng infusion could protect cellular DNA from oxidative stress at least within 2 h."1

American ginseng (Panax quinquefolius) contains a variety of antioxidant compounds like polyphenols and ginsenosides that are believed to mediate its DNA protective effects.1 Previous in vitro and animal research has shown its genoprotective properties, but this pilot trial is the first to demonstrate such rapid effects in humans.1

While further studies with larger sample sizes and long-term supplementation are needed, this preliminary data suggests drinking American ginseng tea could be a simple and effective way to boost your body's defenses against the ubiquitous threat of oxidative stress and associated diseases. So the next time you enjoy a soothing cup of this antioxidant-rich herbal infusion, know that you're likely doing your DNA a favor too.
