Which lavender variety is commonly used in aromatherapy?

Lavandula angustifolia is the most commonly used lavender variety in aromatherapy due to its therapeutic properties and soothing scent. This variety, also known as true lavender, is highly regarded for its calming effects and is often used to alleviate stress, anxiety, and insomnia. Its essential oil is versatile and widely used in various aromatherapy applications, ranging from diffusers to topical blends.

While other lavender varieties have their uses—such as Lavandula latifolia, which has a higher camphor content and can be more stimulating, and Lavandula x intermedia, which is often utilized in commercial products for its robust scent—Lavandula angustifolia remains the preferred choice for its gentle and balancing qualities. Lavandula stoechas, often called Spanish lavender, has a more pronounced floral and herbal scent, but is less common in therapeutic practices due to its varying effects on individuals. This makes Lavandula angustifolia the optimal selection for those seeking the benefits of lavender in an aromatherapy context.
