A 5–10% dilution may be used for short-term acute treatments such as a localized muscle pain blend, used only briefly.
2. Why should citrus oils in particular be used within a shorter shelf life?
Citrus oils are rich in monoterpenes that oxidize quickly, shortening their usable life.

Records help track sensitivities and provide safe, consistent, personalized treatment.

5. Which oil is most often associated with promoting relaxation and restful sleep?
Lavender is the classic aromatherapy oil for calming the mind and encouraging sleep.
