The term "therapeutic grade essential oils" is not a standardized or regulated term in the essential oil industry. There is no formal grading standard used consistently throughout the industry, and no U.S. governmental agency or generally accepted organization "grades" or "certifies" essential oils as therapeutic grade, medicinal grade, or aromatherapy grade. However, some companies use the term "therapeutic grade" to describe their essential oils as a way to quickly convey to consumers that their oils were carefully sourced and tested for use by those practicing holistic aromatherapy.

There are different grades of essential oils, including:

• Grade A: This is the highest quality, therapeutic grade essential oil that uses only organic plants and flowers, distilled at the correct temperatures, and is pure essential oil. These oils are great for consuming for health benefits, diffusing, inhaling, and more. This top grade is safe to mix with carrier oils and apply to your skin and more.

• Grade B: This grade can contain synthetics, anywhere from carrier oils, pesticides, etc. These essential oils are considered food grade.

• Grade C: This grade is more perfume-style oils that also contain synthetics, carrier oils, and other items. This grade is more just for the fragrance aspect of it. You will find this in body washes, shampoos, and more.

It is important to note that the term "therapeutic grade" does not necessarily mean that the essential oil is of higher quality or purity than other grades of essential oils. The quality of an essential oil depends on factors such as the environmental considerations, harvesting, distillation, and bottling. When purchasing essential oils, it is important to research the supplier and look for oils that are pure, high-quality, and have been tested for purity and potency.
