Special care is advised when using essential oils which heighten skin sensitivity to ultraviolet light. These oils include angelica, verbena and citrus oils such as bergamot, bitter orange, lemon and lime. Avoid exposure to ultraviolet rays for a minimum of four hours following application of photosensitive essential oils. Essential oils have different levels of potency. The more potent the oil, the smaller the quantity used.
Most essential oils are safe and nontoxic when proper dilution recommendations are followed.
When in doubt, seek guidance from a professional aromatherapist or medical professional. Essential oils are not intended for use in the treatment of specific medical conditions. For treatment of health ailments, please seek diagnosis and recommendations from a licensed medical practitioner. Essential oils are very concentrated, so it's important to handle them with care. Keep oils tightly closed and out of the reach of children.
