I've been doing more research and ran across two articles that weren't very pro-garlic in terms of its antifungal properties. One study cited the short-lived effectiveness of the active component, Allicin -

Another one cited some antifungal activity, but not a very strong effect - http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=4&sqi=2&ved=0CEk...


It's always interesting to see what's out there.
