This product gives you the control & freedom to create your own customized massage oil. If you are sensitiive to fragrances or have definite peferences and can never find a commercially prepared oil that you like, THEN THIS IS FOR YOU. Simply pick your favorite essential oil ( I use sage or lavender/mint ) and add a few drops ( or whatever you prefer ) to the bottle..and PRESTO!! FYI: You can always just add essential oil to part of a bottle of massage oil if you don't want/need a lot or if you're just trying new essentl oil out.
