Cold-fX is a product derived from the roots of North American ginseng (Panax quinquefolius).^[1] It is marketed as a daily suppliment to improve the body's immune system and aid in preventing common cold and flu, as well as a treatment to reduce the duration and severity of the diseases.^[2]

Clinical Evidence

A study published in the Canadian Medical Association Journal concluded that "ingestion of a poly-furanosyl-pyranosyl-saccharide–rich extract of the roots of North American ginseng in a moderate dose over 4 months reduced the mean number of colds per person, the proportion of subjects who experienced 2 or more colds, the severity of symptoms and the number of days cold symptoms were reported." ^[3]

Comments from the health/medical community

COLD-fX has received several reviews within the health/medical community. Health Canada said that 'CV Technologies Inc. can market COLD-fX as helping "to reduce the frequency, severity and duration of cold and flu symptoms by boosting the immune system."' ^[4] The University of California’s UC Berkeley Wellness Letter called the clinical trials for Cold fX “well designed” and mentioned “promising results” and the statement from Health Canada.^{[citation needed]} The Center for Science in the Public Interest, in a medical review of 10 popular natural cold remedies, concluded that “…Cold-fX is the only remedy we found with any evidence that it might improve your chances of getting through the cold and flu season without coming down with something.”^{[citation needed]} The American Botanical Council concluded that Cold-fX demonstrated “impressive” benefits to users.^{[citation needed]}
