Regular consumption of ginseng during the cold winter months can effectively help prevent the common cold. Notably, this herbal remedy significantly reduces the symptoms and duration of cold infections.
Ginseng is an herb native to East Asia and North America, well-known in communities for its potential to prevent flu and colds. However, scientific evidence supporting these claims has been lacking.
Recently, researchers from the University of Alberta, Canada, investigated the cold-fighting effects of ginseng on over 300 participants. Half of the participants took two capsules of North American ginseng daily for four months during winter, while the other half received a placebo. The results showed that only 10% of the ginseng group caught a cold, compared to 23% in the placebo group. Importantly, those who took ginseng experienced milder symptoms and shorter illness duration (up to one-third less severe).
According to the lead researcher, Tapun Basu, the health benefits of ginseng are attributed to its unique components that enhance the immune system by stimulating immunoglobulin—proteins that act as antibodies. “This can be considered an effective alternative therapy for preventing upper respiratory infections,” Basu remarked.
Experts suggest that the average adult catches a cold at least twice a year, with children and the elderly being more susceptible. Overall, ginseng is beneficial for health; however, pregnant women, diabetes patients, or those with high blood pressure should avoid this herb.
