Essential Oil inhaler for travel

I just finished making up a travel blend for two of my reflexology clients who will be traveling soon.  Inhalers are perfect for travel.  They are easy to use and can provide an aromatic escape when sitting in an airport filled with people.  I chose four essential oils for this blend:    Fragonia for its respiratory support, immune strengthening qualities, and emotional balancing properties;  Ravintsara is highly anti-viral and raises your energy;  Lemon to keep those germs in check.  It’s also a calming and uplifting scent;  Lavender to reduce tension and keep you emotionally balanced.
