I know a little about essential oils. When I am going thru times of high anxiety or panic attacks. I put one drop of lavender essential oil in the middle of a Kleenex and carry it in my pocket. When an attack comes on I go in the bathroom or somewhere private so I don't look like a freak and take in a deep whiff of my Kleenex. I hold it in for a second and keep doing it for like a minute. It seems to work for me. I also do this if I'm having trouble sleeping.
