Elderly individuals are often more sensitive to aromatherapy than adults, so use less of the essential oils and make sure not to use them constantly throughout the day. Elderly individuals typically have fragile skin, so more of the oils are absorbed. Also, essential oils may have interactions with medications, so always be sure to tell your medical team what oils you use frequently.
Any of the recommendations for the other age groups can be used with and around elderly individuals. Just be aware of underlying conditions, and if any adverse reaction occurs, stop using the oils and seek medical attention.
