How can you be sure that your essential oils are of therapeutic grade?
Start by asking the following questions from your essential oils supplier:
Are the fragrances delicate, rich, and organic? Do they "feel" natural? Do the aromas vary from batch to batch as an indication that they are painstakingly distilled in small batches rather than industrially processed on a large scale?
Does your supplier subject each batch of essential oils through multiple chemical analyses to test for purity and therapeutic quality? Are these tests performed by udependent labs?
Does you supplier grow and distill its own organically grown herbs?
Are the distillation facilites part of the farm where the herbs are grown (so oils are freshly distilled), or do herbs wait days to be processed and lose potency?
Does you supplier use low pressure and low temperature to distill essentia oils so as to preserve all of their fragile chemical constituents? Are the distillation cookers fabricated from costly foo-grade stainless steel alloys to reduce the likelihood of the oils chenically reacting with metal?
Does your supplier personally inspect the fields and distilleries where the herbs are grown and distilled?
Do your essential oils meet AFNOR or ISO standards?*
How many years has your supplier been doing all of this?
* One of the most reliable indicators of essential oil quality is the AFNOR (Association French NOrmalization Organization Regulation) or ISO (Internatinal Standards Organization) certification which has set standards for therapeutic-grade essential oils. This standard is more stringent and differentiates true therapeutic-grade essential oils from those with inferior chemistry.
