Be informed about the quality & shelf life of your oils
Avoid undiluted application
Be conscious of personal sensitivities, allergies, contraindications
Know the safety of each oil you work with (we recommend this resource)
Keep away from eyes
Keep away from heat and open flames
Use in well ventilated rooms
Be aware of those vulnerable to essential oils (ie; pregnant women, pets, children, those with compromised health)
Avoid prolonged use of one specific oil; rotate and take breaks to avoid sensitization
Age, health and overall constitution should be considered when using essential oils
Skin sensitivity, open and broken skin must be considered before using essential oils topically
Essential Oils that are potential dermal irritants should be avoided or used with extra caution
Photosensitizing Essential Oils should be known and avoided topically before exposure to the sun
Pregnant women, children, pets and those with compromised health require special considerations; ensure you are well informed about safe use with these groups
Always diffuse in well-ventilated areas especially around small children & pets
Some pets (cats in particular) can have an adverse reaction to some essential oils, ensure they always have freedom to leave the area when you are diffusing or using essential oils
Baby's nasal passages are fragile and still developing; it's best not to diffuse essential oils in the same room as a baby
