The only Blue Cypress essential oil source in the world. This is true for several of Young Living's oils. In fact a chief competitor has copied as much of the path forged by Young Living as they can. The only problem with that, and it's a big problem, is they don't have a single company owned and operated farm.
Another reason Young Living is the leader in essential oils. They're paving the way. Other companies can only follow from a great distance.
