Lavender is referred to as the swiss army knife of essential oils. It is gentle and has highly versital properties, such as; burn-aid, soothes irritrated skin, relaxant, anti-anxiety, decerease severity of headaches and migrains.
 
I use lavender in my practice through diffusion, prompting clients to inhale a drop from my palms throughout the bodywork session, or diluting a few drops in a carrier for a high-energy client looking to down-regulate.
