I recently used oil of oregano for an ear infection. I was amazed at its ability to stop my ear infection in its tracks. Tastes nasty, though.
I guess the cool thing about
taking garlic or oregano oil regularly is that they offer other benefits--like being anti-virals, anti-fungals, etc.
Jeni Patel recommends and explains correct usage of oil of oregano on her website for folks with IBD. Maybe she discusses garlic as well...?
