Important Notes: The essential oil information provided within the Essential Oil Properties & Profiles area is intended for educational purposes only. This data is not considered complete and is not guaranteed to be accurate. The oil photos are intended to represent the typical and approximate color of each essential oil. However, oil color can vary based on harvesting, distillation and other factors. Profiles for several absolutes are included within the directory, and are denoted as such.

General Safety Information: Do not take any oils internally and do not apply undiluted essential oils, absolutes, CO2s or other concentrated essences onto the skin without advanced essential oil knowledge or consultation from a qualified aromatherapy practitioner. If you are pregnant, epileptic, have liver damage, have cancer, or have any other medical problem, use oils only under the proper guidance of a qualified aromatherapy practitioner. Use extreme caution when using oils with children and give children only the gentlest oils at extremely low doses. It is safest to consult a qualified aromatherapy practitioner before using oils with children. For in-depth information on oil safety issues, read Essential Oil Safety by Robert Tisserand and Rodney Young.
