It was very difficult to compile a list of oils and products to be avoided during pregnancy. Each aromatologist has a different opinion. We feel that an oil that is unsafe is an oil that has been adulterated or one that is used improperly. Oils that are diluted, applied externally and in moderation should not create a problem. This list is a compilation of the safety data contained in aromatherapy books written by the following authors: Ann Berwick, Julia Lawless, Shirley & Len Price, Jeanne Rose, Robert Tisserand, and Tony Balacs.
