I trust Young Living’s oils because of their 20 years of experience, they are truly pioneers in this industry. The soil that grows these plants/shrubs/trees has never been exposed to chemicals or pesticides. They have perfected the distillation process to make sure that every drop of oil that is extracted from the plant is pure and therapeutic grade. It’s Seed to Seal promise is what sets Young Living apart from all other Essential Oil companies. To learn more about the Seed to Seal promise click here.
