Sage White

Safety
White Sage is high in 1,8-cineole, and Tisserand/Young warns that essential oils high in 1,8-cineole (White Sage) "can cause CNS and breathing problems in young children, and should not be applied to or near their faces under ten years of age (Tisserand, pages 656-657, 273). Tisserand also writes: "Any oil with 40% or more 1,8-cineole should not be applied to the face of infants or children or otherwise inhaled by them" (page 109). Appropriately diluted for the child, the oil with a carrier will fall well-within the range of safe use, as it would contain far less than 40% 1,8-cineole. 
Regarding inhalation/diffusing, Tisserand notes that "for children of 5 years old or less, direct inhalation should be avoided. Direct inhalation includes inhaling essential oils from the hands, a cotton ball, a nasal inhaler, a bowl of hot water or similar. Indirect, or ambient inhalation, is safe for young children, and includes any method that vaporizes essential oils into the air (pages 273, 656-8).” 
Avoid contact with the eye. Essential oils are lipophilic, meaning they are attracted to fat—like the membranes of your eye and skin. Essential oils are hydrophobic, meaning they do not like water. Flushing with water will only send the essential oil back to the eye's membranes. Wiping with carrier oil will create another fat for the essential oil to be attracted to other than the membranes of the eye. We’ve not known this to cause permanent injury or long-term discomfort, but if you feel concerned, please call your doctor if necessary.
