Do essential oils need to be refrigerated?
Do real essential oils (without additives) freeze?
Coloured glass bottles, air space, and temperature
The biggest enemies of essential oils are heat and oxygen. Citrus oils and the chamazulene-containing oils are more susceptible to thermal degradation and should be kept in the fridge. Keep all essential oil airspace to a minimum. Once the oil container is half full, then its time to transfer the oil to a smaller bottle. This will significantly extend the useful life of the oil. Keep the airspace to a minimum and the temperature at 75ºF or below (even lower in the case of citrus and other oils more susceptible to thermal decomposition). This way, you can keep the oils smelling nicer for longer periods as well as extend their effectiveness.
Do the best quality oils come from the "first pressing" or first distillation of the plant material?

Is company Y (fill in name) the only company in the world who sells pure or therapeutic grade essential oils?
Does this mean there is no such thing is therapeutic grade? No, but just realize that any therapeutic grade standard out there right now is an internally derived company standard… In the end, for most people who don’t have access to the proper testing equipment, it all boils down to who do you trust to give you the pure oil. If the leader of a company has demonstrated questionable ethics in general, then its probably not a company whose “therapeutic grade” standard would really carry much weight and should not be taken seriously by an educated essential oils consumer.
