Thank you Lori - I did mean quality.

The process of olfaction involves other modalities like vision, hearing, memory, thinking, analyzing, etc. When you smell a natural oil it evokes some memory and emotions that may be inherited from your ancestors who enjoyed these aromas long before you. This is why you have a feeling of connection or “goodness” of oil.
