Sometimes I think maybe I'm a little to skeptical of the whole "essential oils" thing, maybe people that use them are onto something and I'm being too judge judgmental... Then I read stuff like this page posted by an oil using friend. It includes gems like:

1. The molecules of Essential Oils are small enough to circulate through human tissue bringing nutrients to the cells and carry waste and toxins out of the cells.

2. Essential oils also carry electrons and oxygen into human tissue.

6. Hence, some oil molecules gravitate to muscle tissue, others to nerves, others still to the digestive system, and others to the heart, etc., each administering benefits, including the removal of toxins and the opening of emotionally stored memory in the DNA.

Like sure, scent is a funny thing with how it connects to emotions and memories, but I'm pretty sure it isn't because the essential oils are helping to flush memories out of your DNA.
