Organic Oregano Very rich / strong flavor - which I like. And the only Organic available for purchase, at the time of this review. February 2, 2014
Oregano oil Is not the real oregano oil , the combination is more olive oil and oregano oil less so you don't have the real oregano oil that you need for your body ! Smell like olive oil not like oregano and souls be vice versa ! I try but not working for me personal , I like the real oregano oil ! January 6, 2013
It burns! Yeah, this product definitely burns and that's what it's supposed to do. It's also got a really strong smell. I could smell it right out of the box even before opening the bottle. This product is great and as I expected. Now I just have to see about the results. August 13, 2012
I like it... Great product, great price, great value. I love Swansons organic selection March 29, 2012
Natural Factors Oil of Oregano This is a must have in every one's line of supplements and health care products! Read up on the benefits of Oil of Oregano and then buy this brand which is tops and extremely well priced through Swanson Products. January 31, 2012
Great Oregano I have used other oregano oils - most of them were not effective. I have found this oregano oil to be very effective and at a great cost compared to other expensive products. I highly recommend this oregano oil. I use it internally as well as externally on the bottom of my feet! December 15, 2011
The best This is the best oregano oil you can buy. It's much, much cheaper here than in stores, and it's one of the purest you can find. Works like a charm, and best of all, it's organic. Can't beat it. May 15, 2011
Disappointed I have used certified oreganol oil from another vendor with over 80% carvacrol for several years now and this particular product doesn't even come close! It doesn't even have much of the typical oregano "burn" even with 20 drops or so it is so diluted with olive oil. I only tried this product because the label said it had a minimum of 80% carvacrol, money is really tight and I was trying to save a few bucks...what a waste!! January 3, 2011
