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.
What do you use oregano for?
A shopper on Jul 14, 2017
BEST ANSWER: Oregano Essential Oil is part of the Rocky Mountain Oils Cleaning collection. It can also be used to support the immune system ans well as repel insects. Thanks!
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.
