One of the most important factors when choosing essential oils is purity. Look for products that clearly state the botanical name of the plant and provide information about the oil's origin. For example, true lavender Essential Oils in the USA is commonly identified by its botanical name, Lavandula angustifolia. A clear botanical identity helps distinguish the intended plant species from similar oils or fragrance products.
Buyers should also check whether the product contains additives, synthetic fragrances, fillers, or other ingredients. Terms such as “100% pure” can be useful, but they should ideally be supported by detailed product and testing information. The term “therapeutic grade” is commonly used in marketing but is not a standardized regulatory grade, so buyers should focus more on measurable quality information and transparency.
