Which essential oil is known for having a heavy, rich aroma and is classified as a base note?

Myrrh is recognized for its heavy, rich aroma, characteristic of essential oils classified as base notes. Base notes are typically those that exhibit deeper, more lasting fragrances and form the foundation of a blend, providing a sense of stability and depth. Myrrh has a complex profile with sweet, balsamic, and earthy undertones, contributing to its grounding properties and making it popular in both aromatherapy and perfumery.

Base notes usually evaporate slower than top and middle notes, giving a blend longevity and helping to anchor the lighter, more volatile scents. The thick and resinous quality of Myrrh enhances its classification as a base note, differentiating it from lighter, more ephemeral oils such as rosemary, eucalyptus, or lemongrass, which are generally categorized as middle or top notes.

This understanding of fragrance classification is essential in aromatherapy, as it aids in creating harmonious blends that achieve the desired effects for well-being and mood enhancement.
