AroMed's adult essential oil synergies address a variety of commonly experienced issues... sleep disturbances, stress and anxiety, respiratory issues, headache and so much more. AroMed's essential oil selections are based on both historical and current evidence- based information supporting their use. You may purchase your blend in the 10 mL pure oil synergy, a 10 mL roll-on in jojoba (already diluted for easy application), or in a personal nasal inhaler for quick, easy use. Inhalers maintain their aroma, and remain effective, anywhere from 6-9 months. All synergies target a particular body system, are uniquely effective and smell great!
