Essential oils are concentrated plant extracts that retain the natural smell and flavor, or “essence,” of their source. Essential oils are compounds extracted from plants. The oils capture the plant’s scent and flavor, or “essence.” Unique aromatic compounds give each essential oil its characteristic essence.

Essential oils are obtained through distillation (via steam and/or water) or mechanical methods, such as cold pressing.

Once the aromatic chemicals have been extracted, they are combined with a carrier oil to create a product that’s ready for use.

The way the oils are made is important, as essential oils obtained through chemical processes are not considered true essential oils.

Essential oils are often used in aromatherapy, a form of alternative medicine that employs plant extracts to support health and well-being.

Essential oils are most commonly used in the practice of aromatherapy, in which they are inhaled through various methods. Inhaling the aromas from essential oils can stimulate areas of your limbic system, which is a part of your brain that plays a role in emotions, behaviors, sense of smell, and long-term memory. Interestingly, the limbic system is heavily involved in forming memories. This can partly explain why familiar smells can trigger memories or emotions. Essential oils can be inhaled or diluted and applied to the skin. They may stimulate your sense of smell or have medicinal effects when absorbed.
