Oregano has so many factors that enhance phsysiologic well being apart from the perfection of being a pure untainted essence it is beneficial for germ sanitization, great also for small children's (as long as they do not touch their nose in 1st 5 minutes) fingers . It is also great for nasal and lung healing, up-grades immunity system, and used in clothes dryer for long range healthy immunity on all clothes. I also find a few drops in my shoe linings, improve foot + toe safety + reduce shoe odor.
Oregano is 100% perfect for many uses

love this oil.
I diffuse oregano and cinnamon in my house every night. I feel like it helps clean the air and surfaces. I love the way it smells. It smells natural and clean-no chemical yuck. Don't worry about Pizza parlor smell from the oregano. It doesn't smell like that.
Very happy with this oil. I will order more.

Definitely smells like oregano :)
It definitely smells like oregano. I've been diffusing it together with other oils to help keep sickness away. It is more pleasant when combined with other oils...unless you want your house to smell like a pizzeria. Ha! I would recommend this oil, especially for diffusing during sicknesses or when you want to avoid getting sick. I've heard it can be used for cleaning, but I've not used it in that way. I think I'll stick to diffusing it for now. :)

I'll keep using it
I really like it, the other day I was so sick and my throat was hurting so bad. I decided to put 1 drop of the oregano oil with coconut oil in my mouth for five minutes and swirl around my mouth once a while then went to bed. When I woke up and the pain all gone. I also use this at least once a week to keep my gum healthy. I think it's little strong like other people said but if keep my pain away and keep my gum healthy I would use anything. Thank you Rocky Mountain for the awesome product.

Has anyone tried this oil to get rid of warts on hands? If so, did it work?
Jon R on Jul 18, 2017
BEST ANSWER: We have used it on plantar warts on the feet and had success. It's very strong, so we had to be careful not to get it on anything else. Since the bottom of feet are so tough, it did not cause pain or burning on the feet.

This may be a silly question but I have smelt Doterra’s oregano oil and the smell is much more appealing than the the RMO I received today. What would cause the difference in smell?
Mandy C on Mar 7, 2018
BEST ANSWER: Many factors will play a part in the end result and sent of an oil. Such as growing patters, country of origin, weather patters, when the oil was harvested, etc. Because essential oils are from living plants that do not follow exact chemical formulas the scents will vary based on location and can even change from batch to batch.

Thanks! RMO -Team
