Study: Garlic (2001) Colds & Flu



Learn more about colds and flu.

Garlic may be helpful in preventing colds and flu due to its anti-bacterial properties. One researcher thinks that taking garlic may reduce chances of catching a cold by half.

In a 2001 study in England, 146 volunteers took either a placebo or capsule of an allicin-containing garlic supplement daily for 90 days during the winter. 24 colds were recorded among those taking the supplement, compared to 65 amongst those taking the placebo.

The study also found that those taking the supplement who did catch a cold were more likely to make a speedier recovery than those taking the placebo and the chances of re-infection following a cold were significantly reduced.
