Holobon,
It's a coincidence you should mention aromatherapy oils, as i've just been introduced to the delights of Clarisage oil :)
I hear Clarisage can aid meditation or channeling, as well as stimulating the mind in general and helping to lift feelings of depression and anxiety. I expect you know about it's hallucinatory and migraine-inducing effects when mixed with alcohol - something i intend to take every precaution not to do!
Sometimes i use a tiny amount of rose oil on my hands when treating the face area, just to give a pleasant relaxing smell, especially with first time clients when touching the face can be a little unnerving.
Take care
Graham
