There is a significant difference between essential oils that simply smell good and those that are therapeutic-grade.
Independent laboratory testing proves that Young Living essential oils meet and often exceed industry requirements, and as stewards of nature's plant remedies, Young Living maintains higher internal standards, built upon the magnitude of rigorous in-house Quality Assurance requirements. This standard is known as "therapeutic-grade." In order to achieve therapeutic-grade classification, each essential oil must achieve the designation naturally, without excess manipulation and refinement, and meet specific criteria in four key areas: Plants, Preparation, Purity, and Potency.
PLANTS: Young Living products are produced from the right plants, grown in exceptional soil, and harvested at exactly the right time.
PREPARATION: Honoring a strict commitment to respect and protect the time-honored methods of distillation, Young Living makes every effort to preserve "nature's living energy" in a manner as close to its natural state as possible. Using pure mountain water free of addivitives, Young Living has a proprietary, stainless steel distillation process.
PURITY: Achieved through the use of quality plants and meticulous preparation, and not through ultra-refinement, the finished product is 100% pure. Young Living has a proprietary, stainless steel distillation process.
POTENCY: To guarantee that products exceed existing world standards and meet higher internal standards for potency, the finished oil's phytochemical profile is analyzed to ensure it delivers optimal amounts of every key plant compound.
