The EO Pocket Reference guide will tell you all about the historical, medical, & cultural uses of every essential oil sold by Young Living. It’s an amazing resource! (If you don’t already have it and need more info like this, let me know!)
Lemon essential oil is not distilled in the same way as most essential oils. Most essential oils come from bark, stems, flower petals, or leaves. But in this case, lemon oil comes from the rind of the fruit. It must be cold pressed in order to get to the oil. It takes 3,000 lemons to produce one kilo of lemon essential oil.
Young Living goes farther than any other company worldwide to ensure that its lemons are healthy, in prime condition for cold pressing, and that the essential oil is created with the perfect balance of chemical constituents for full health benefits (emotional and physical). YL essential oil is not adulterated or diluted with any carrier oil or synthetic chemicals.
