I use Doterra Oils on me and in my business in diffusers to help calm the grooming environment. https://www.mydoterra.com/dedecroy/#/
I use this everywhere, on my temples when I feel a head ache coming on, in my mouth for bad breath, on my skin when I need muscle pain relief. I also enjoy it in my diffuser. In my opinion only, I am not a Doctor!
