GINSENG- FOR FLU
If you get
battered by frequent respiratory infections, consider taking a daily dose of
ginseng—starting now. Taking ginseng regularly well in advance of the germy
fall and winter seasons can help prevent colds, influenza, and respiratory
syncytial virus (RSV), finds new research published in the journalNutrients.

Because there is
not yet a vaccine for RSV, and because flu vaccines aren’t 100% effective, researchers
decided to investigate red ginseng extract, which had already been proven a
worthy immune-enhancer (ginseng’s ability to successfully help ward off colds
was shown in a 2006 study, and earlier research also suggests it has antiviral
action against RSV and flu). In this new study, Sang-Moo Kang, PhD, a
professor at the Institute for Biomedical Sciences at Georgia State in Atlanta,
who specializes in developing vaccines that protect against bacterial and
viral disease such as influenza and RSV, discovered that red
ginseng extract protects the survival of human lung epithelial cells infected
with flu -influenza' hh='1'>influenza virus. What’s more,
treatment with red ginseng extract reduced the expression of genes that cause
inflammation.
Several species of
ginseng and types of ginseng extracts exist, but to fight the flu, Kang recommends Korean red ginseng, which is a cured
ginseng root extract. "Ginsenosides are active ingredients in Korean
red ginseng that help the body deal with stress, disease, and fatigue,"
says Kang. "These substances are have anti-inflammatory, antioxidant, and
even anti-carcinogenic properties," he adds.
