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: There are many who consider Oregano to be more effective than antibiotics. It is a natural antibiotic that can be applied topically or even ingested and/or diffused. It's a very strong oil that can cause irritation, so for those with sensitive skin use with caution. Also, be careful with children, as their skin is often much more sensitive than audits. Also, prolonged exposure can become irritating as well, so be careful. It's a healing oil, that fights the bad stuff and encourages the good. A truly essential Essential Oil.
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: There are no still questions! Nature is never stagnant. I like to use honey as an analogy. Natural honey always has variations in taste depending on the plants the bees used. Oil batches will vary for a similar reason. It depends on what the plant "eats". Some of the variants will be:
different vendor's for plant procurement
colder weather
dryer seasons
wetter seasons
differences in sunlight
slight differences in soil variation
time of harvest
It's pretty common for different batches if the same oil to have smell variations. If your oil is tested & meeting the right levels of constituents, it's good to go.
Is your oregano oil edible, for what condition and what would be the dosage?
Dagmar L on Oct 30, 2017
BEST ANSWER: At this time, we do not provide recommendations or suggestions on ingestion because the body can safely absorb essential oils by topical application or diffusion. However, all of our oils are 100% pure, natural, and therapeutic. We have incredibly high quality standards and back it with it S.A.A.F.E. Promise and 100% satisfaction guarantee. https://www.rockymountainoils.com/quality

We also believe in the safety of our customers. We feel that essential oils are very potent and can be dangerous if not used correctly.

As long as customers have proper guidance from a trusted professional or Aromatherapist, our oils are of the quality to use them internally with wisdom and safety. There are definitely some oils that should never be ingested.

If customers do choose to ingest the oils, we suggest consulting an Aromatherapist or trusted health professional for guidance. As a company we can not provide dosing suggestions or directions on how to ingest if you choose to do so.

What is the potency, concentration, percentage of carvacrol in this product?
A shopper on Aug 31, 2017
BEST ANSWER: One of the main reasons RMO is my go-to oil company is because they provide GC/MS test results from a verified third party, independent lab for each one of their products. My husband used to work as a chemist & he ran those tests on biomaterial at Baylor in Houston TX. I understand what they do & how to read the reports. Each RMO oil has a number on the bottom of the bottle. On their website menu type, click Quality, input the number & up will come the report. Check the amount of carvacrol & other compounds in the oil. I have a bottle of OreganoEO w the #015055. Upon checking the report, carvacrol is about 3/4 of way down the page. Now unfortunately my particular batch has a test date from two years ago which means this batch of oil is too old to sell now or they need to redo & update the test data but at least I know the test was done & at the time of my purchase was @ a year old, still valid for my oil.
