ABSTRACT:
One hundred forty-six volunteers were randomized to receive a placebo or an allicin-containing garlic supplement, one capsule daily, over a 12-week period between November and February. They used a five-point scale to assess their health and recorded any common cold infections and symptoms in a daily diary. The active-treatment group had significantly fewer colds than the placebo group (24 vs 65, P.001). The placebo group, in contrast, recorded significantly more days challenged virally (366 vs 111, P.005) and a significantly longer duration of symptoms (5.01 vs 1.52 days, P .001). Consequently, volunteers in the active group were less likely to get a cold and recovered faster if infected. Volunteers taking placebo were much more likely to get more than one cold over the treatment period. An allicin-containing supplement can prevent attack by the common cold virus.

INTRODUCTION:
The common cold is the world's most widespread viral infection, with most people suffering approximately two to five colds per year. Over 200 different viruses cause infection and cold symptoms; the most common, rhinoviruses, account for 30% to 40% of adult colds. Re infection is prevalent because of this wide variety of infectious viruses. 1 Published literature on the activity of garlic against viral infections is sparse. 2,3 One report 4 describes that during an influenza epidemic.
