Fresh and Citrusy sweet. Love Lemongrass!
I love is a perfect blend of the fresh Citrus you would expect from Lemon and also slightly...sweeter? at the same time. I make my own Deodorant and frequently use the Lemongrass to scent it. It is also very nice in my Diffuser and around the house. Thank you so much RMO! ??

I switched to Rocky Mountain Essential Oils because I wanted something high quality. With all the good things I’ve heard about it I had to try. So far I really like these oils. They are strong so you only need a few drops. Great quality and amazing scent!!!

Is this okay to use on my face?
A shopper on Jun 4, 2018
BEST ANSWER: We would generally not recommend using Lemongrass Oil on your face as it is considered a "hot" oil and can cause irritation on sensitive areas. If you do choose to use it on your face, we recommend diluting it to a .5-1% dilution with a carrier oil and keeping it away from the eyes. A dilution chart can be found on our website under the "learn" tab.

I’ve heard that some EOs are harmful to cats (Lemongrass being one of them) when diffused. Do you know if this is true? If so, which oils are they?
Valerie M on Aug 13, 2018

At this time, we have found insufficient research about using essential oils on or around domestic animals, including procedures and possible reactions. Because of this lack of research, we are unable to advise how to use essential oils with pets.

The websites below can be great tools. Keep in mind, we are not associated with these websites.
