I think this is an excellent product, but it is extremely powerful and I wish it came with more comprehensive information about safe and proper usage. Most of what I found online emphasizes benefits but did not discuss side effects/risks or ways to reduce or avoid irritation. I recommend this product, but with the following caveat: Get ahold of a copy of the (I think) out of print book "The Cure Is in the Cupboard" which discusses dosing and applications. It still downplays potential side effects (written by seller) but is extremely helpful. I recommend getting both the lower potency (not super strength) AND this super strength one and experimenting with different applications. You may find that you prefer/tolerate the lower strength better for some applications and reserve the higher potency for stronger needs or for internal usage in caps (goes further). One note, you can put a few drops in an empty gelatin capsule and take during/after meals rather than putting under tongue or drinking as the manufacturer directs, to reduce potential for irritation. I prefer this after trying various means. I do highly recommend for tooth and gum issues, but it can cause teeth sensitivity in super strength. 1-2 drops on gauze and left on tooth, changed a few times a day. After any acute situation is under control, you might want to switch to lower strength. Fewer side effects such as nerve irritation, shooting pains (neuralgia type), tooth sensitivity, etc. Unexpected benefits and side effects included more energy, mental clarity, and drastically decreased appetite, more stable blood sugar. In sum, extremely powerful and effective antimicrobial that works really well. Awesome product, but very powerful.

I think it's a very good product, but quite expensive. I wouldn't lower the stars just because of the price - if you could afford it, go for it, but I switched to another brand as it's still good but more affordable to me. Otherwise, this one comes from a great company and I like all their products, but they really come too expensive to me.

This oregano oil is very strong and extremely effective. My mother uses it to dull pain and help with her emphysema, and I've taken it and cured a cold on the first day. It's a great daily supplement to help your immune system and the rest of your body.

This is a mainstay in my arsenal against cold, flu, bug bites, warts, skin problems the list is endless. I have not used an antibiotic in twenty years and I give this to my grandchildren from babies on up. It is the most powerful product I have used for fighting the many bugs that are passed around and I have used many natural products that though good, did not compare.

I had a dreadful chest infection recently and was advised in a local health food shop to try some Oreganol P73. After trying a small travel size bottle, I was impressed enough to go on to purchase a bigger, triple strength bottle. This is really expensive in the UK, so I was delighted to find that iHerb shipped to the UK at a reasonable cost. Even after paying VAT and a Royal Mail fee for them collecting the customs duty, it's still way cheaper to buy from iHerb.
