I suck on a zinc lozenge, as it kills viruses in the throat. One drop of oil of oregano, or olive leaf extract under the tongue, 3 times a day for 3-7 days until the symptoms subside. Beta glucan is also an option as it raises immunity, and combats sickness. I have written an article on the subject http://hubpages.com/health/Is-it-a-cold-or-allergy... with many other recommendations for the treatment of cold and allergy. I also make chicken soup, as it also kills viruses. http://hubpages.com/food/chicken-and-dumplings-sou... Another approach is prevention, take a multi vitamin, and D3, wash your hands when around sick people, and get plenty of rest.
