The quality of essential oils that you use MATTERS so much! The integrity + purity of Young Living oils is the reason why I choose them over other oil companies. Young Living is the world leader in essential oil research and distillation. They oversee the entire process of creating these essential oils- the planting of the seeds, the growing and harvesting of the plants, the entire distillation process, and the quality control of the final product bottled for you and me. The immense amount of testing done on each batch of oils is incredibly thorough, and I love that I can take a tour of their farms at any time. Quality and ethics are important to me! Because of this, Young Living is the only brand that I recommend at this time. You can check out more about the Seed to Seal process here.
