Blended oils are just that.  Blended.  Several aromas.  
RC - A mix of f Spruce, Cyprus, and three types of Eucalyptus (E. globulus, E. radiata, and E. citriodora).
Panaway - A mix of Wintergreen, Helichrysum, Clove, and Peppermint.
Thieves - A mix of Clove, Lemon, Cinnamon, Eucalyptus Radiata, and Rosemary.

Nothing more, nothing less.  One bottle carefully crafted for full impact.

What blended oils does Young Living produce?  Here is a full product list.  No worries, I'm overwhelmed at all of the oily goodness, too!
