6 Uses for Fennel Essential Oil

Used for centuries in a variety of ways, fennel is known for its distinct licorice flavor and aroma. Today, fennel essential oil can be used for culinary purposes, as well as internally to promote a healthy respiratory system, healthy digestion, and more. 

Fennel is an evergreen perennial native to the Mediterranean. It produces flowers, fragrant leaves, and most importantly, fennel seeds. The essential oil is extracted from the seeds. 

Oil Chemistry

Fennel essential oil is made up of monoterpenes and chemical components known for their energizing and uplifting aromatic properties. The chemical makeup of this oil contributes to the sweet, licorice aroma of fennel. Trans anethole, the monoterpene phenylpropene which is the primary chemical constituent of the oil, is distinctly sweet. It’s 13 times sweeter than table sugar.

Fennel is also comprised of chemical components called ketones, which contribute to the calming properties, as well as the oil’s ability to promote healthy respiratory function and healthy digestion, when taken internally (source).

Benefits of Fennel Essential Oil


Supports Healthy Digestion

One study had participants take two capsules containing 42 mg of curcumin and 25 mg fennel essential oil twice daily with meals. After 30 days, the participants took two capsules once daily with a meal. The researchers found that there was significant improvement in bowel regularity and quality of life in the study participants as a whole. Numerous explanations for the observed improvements were proposed, including potential modulation of smooth muscle function in the bowel wall (source). 

To use: add a drop or two to 8oz of water or add 1-2 drops in a veggie capsule. You can also mix a few drops of oil with fractionated coconut oil and massage over your abdomen to relive stomach indigestion. 

Provides Respiratory Support

According to one study, certain ingredients in essential oils, such as fennel, could serve as a natural treatment of lung and liver conditions caused by air pollution (source).

To use: add a few drops of the oil to 8oz water or another beverage.

Supports Healthy Metabolism

When you are feeling sluggish or bloated, taking fennel oil internally may help to promote healthy metabolism, liver function, and circulation.

To use: add 1-2 drops in a veggie capsule and take after a big meal.

TIP: remember, when using essential oils for cooking, start small. Even a toothpick’s amount can add a lot of flavor to your dish, so start with the bare minimum, and add more essential oils as you go to ensure that the flavor of the oil doesn’t overpower the meal.
