Has anyone had any joy with essential oils applied to the soles of their feet? I am getting some for sleep issues, but I wondered if anyone has tried essential oils for CFS, and which ones they tried for energy? I know my absorption is not great so I was encouraged to read: "If applied all over the bottom of the foot, the oil can be detected in every cell of the body within 20 minutes." I know some people that say applying peppermint oil really gives them muscle relief, and even (for some odd reason that no-one knows) applying oil to the back of the ear, can have some interesting benefits. Any comments?
