I can not believe I have finally come across an incredible brand of essential oils that are 99% plastic free; the only tiny bit of plastic is the inside of the lid which is something that will be changed as soon as possible in the future! I will always support brands that are striving for change and these pots have already cut out a lot of unnecessary plastic from the essential oils you see everywhere! This organic Frankincense oil is obtained from the boswellia sacra, a tree in the Burseraceae family. Because of its knotty appearance, they are often referred to as a desert bonsai. Frankincense essential oil has historically been burned in sacred placed and during religious rituals.
