Please Note: Dilution Chart information has been compiled from books written by authors Connie and Alan Higley; D. Gary Young, ND; Essential Science Publishing; and Valerie Ann Worwood. When conflicting information was present, I chose the most conservative information for the safest possible application. Still, understand that you are using each essential oil at your own risk, even with the safety information given above. Try only small amounts the first application, watching for adverse reactions.
