Once the plant matter is harvested, the essential oils are extracted using steam distillation, cold-pressed, or another natural method. There are few extraction methods that actually give you 100% PURE and all-natural end products. Essential oils produced with the aid of chemical solvents are not considered 100% pure essential oils, because the solvent residues can alter the quality of the oils. We do not use oils from anywhere that uses chemical solvents. We’ve made sure we only use the BEST extraction methods to get you the best essential oils available.
