Reason #4) Oxidation Oxidation is the process of the breaking-down of molecular structure. All essential oils oxidize. Some oxidize faster than others (see Reason #2) Shelf Life). There are three things that cause e.o.s to oxidize; heat, air, and light. Therefore, the best case scenario for storing them is in a cool, dark place in with tightly-sealed, dark glass containers. Essential oils sitting on a store shelf are exposed to heat and light which are only going to degrade t

Reason #3) Safety Information; What do you know about safety issues concerning individual essential oils? The many benefits are published far and wide. My experience is the safety considerations are not as widely broadcast. The information is available can be confusing or vague. Though the benefits of an oil may generally outnumber the safety concerns, they in no way outweigh the concerns. Such concerns can include initiating an asthma attack, cause severe burns, and even hav

Reason #2) Shelf Life Each and every essential oil is unique. Each and every essential oil is the sum of an array of constituents. The ratios of these constituents dictate which chemical families to which the essential oil "belongs". In turn, each and every chemical family has common properties typical to the EOs which fall into that family. Something to keep in mind, regardless of common constituents and properties, is each and every batch is different than the one before -
