I have been using their oil of wild oregano Super Strength Oreganol for well over 10 years now, and that stuff is a literal life saver. It's a little expensive, but well worth every penny. The lady at the health store that originally recommended it to me well over 10 years ago told me at the time that this was the only oil of oregano supplement she knew of that was lab certified. If you ever start coming down with something, try taking this stuff. I bet you'll be very pleasantly surprised at how well, and fast it works. I know it's kept me from having to make a trip to the urgent care clinic several times
