100% Pure Essential Oils

Looking for 100% pure single component essential oils!  Not diluted!  Not even with other essential oils! 

Did you know that many expensive essential oils are cut with less expensive essential oils?  Take Patchouli, many times cedarwood or other less expensive essential oils are also in the "Patchouli" oil.  And many companies wouldn't even know this unless they know how to read a Gas Chromatography and Mass Spectrometry report.  Yes, it would be 100% essential oil, but it wouldn't be all patchouli!  Beware of inexpensive oils!
