Sweet Fennel

Essential Oil Allies: Sweet Fennel


Fennel essential oil is obtained by steam distilling the seeds of Foeniculum vulgare var. dulce. It is mainly grown and distilled in France, Spain, Germany, Hungary and India for its essential oil.

Originating around the Mediterranean basin, this hardy perennial has been introduced to and naturalized across Eur-Asia, India and North America—adapting to most temperate climates. An ancient plant, the Ancient Chinese, Indian, Egyptian and Roman cultures employed this herb for medicine and culinary uses. According to Grieve: “It has followed civilization, especially where Italians have colonized.

Like many plants from the Apiaceae family, fennel’s seeds have been used for centuries to address digestive complaints (mainly through chewing the seeds, infusions and tinctures). Sweet fennel has also been used to promote lactation, to aide in eyesight, ward off hexes and evil spirits and as a detoxifier/slimming agent (according to Grieve, it was originally called “marathon” by the ancient Greeks, derived from maraino, to grow thin).

Hildegarde von Bingen realized both physical and emotional benefits of fennel: “A person whom melancholy is harming should pound fennel to a liquid and rub it often on his forehead, temples, chest and stomach. His melancholy will stop.” This statement made hundreds of years ago still holds true—fennel essential oil is quite an uplifting and clearing agent. Its volatile oils ease into the mind-body, clearing away the cobwebs so thoughts and creativity may be freely and playfully expressed.

Sweet fennel essential oil shines in the realm of woman’s health, supporting breathing space, spastic pain and uplifting the mood. Fennel is widely used to support digestion but an herbal tincture, infusion of the seeds or chewing the seeds is best used for this versus the essential oil. However there are always exceptions: check out this online French Aromatherapy course to explore the internal use of essential oils, a great way to support digestive issues once you have solid guidelines.

Following are core applications for the essential oil:

System Core Applications
Reproductive Balancing to hormones, PMS, dysmenorrhea, amenorrhea, lack of or reduced sexual drive, lack of or reduced milk flow in lactating woman (fennel tea is indicated or inhalation of fennel e/o), cramps, menopause, perimenopause
Respiration Anti-inflammatory, bronchodilator, spastic coughing
Musculoskeletal & Circulatory Muscle spasms or cramps, general muscular aches and pains, detoxifier
Nervous/ Psyche/ Emotion Inflamed mind, difficulty communicating, mental fatigue, expressive, creativity, light-hearted, throat & sacral chakras
Digestion Massaged onto the abdomen for gaseous cramping, inhaled to promote digestive fire, and quell nausea

Chemistry Highlights: Sweet Fennel essential oil is rich in phenylpropanoids, specifically trans-anethole, which lends to its “anise-like” aroma, and methyl chavicol.

Of note: sweet (dolce) fennel of is not to be confused with the bitter (amara) variety, which is not used in aromatherapy due to its relatively higher content of fenchone and its more “harsh” nature.


Is Sweet Fennel Essential Oil Safe?

Due to its trans-anethole content, fennel essential oil should be avoided by any route (method of application, especially oral) in pregnancy, breastfeeding, endometriosis, and estrogen dependent cancers. Trans-anethole exhibits estrogenic actions. Essential oils with estragole (Methyl chavicol) should also be used carefully (especially internally) for its effect on the blood.


Blending with Sweet Fennel Essential Oil

Fennel stands well on its own and may over-take a blend (depending on country of origin)—start with fewer drops and add more as your blend matures and your olfactory sense sees fit. When blending with fennel, think about the core issue you are trying to address AND how you cook using fennel as it gets along quite well with many other culinary herbs and citrus.

Fennel essential oil swiftly, but sweetly, announces itself: bringing gifts of honey, clear blue skies, open meadows and pollinating insects. It exudes a slightly sweet-floral note, reminiscent of almond and anise confectionary. A bright, clean smell is apparent: memories of seafoam and clean blue water. The dry-down brings an expressive honey-hay aroma that playfully communicates fennel’s memory of its nectar-giving umbels that elegantly looked up at the same sky as you.

Fennel essential oil blends well with: other members of the Apiaceae family (Angelica archangelica, Coriandrum sativum), friends from the Lamiaceae family (Clary sage (Salvia sclarea), Sweet marjoram (Origanum majorana), Rosemary ct. cineole (Rosmarinus officinalis ct. cineole), Peppermint (Mentha x piperita), the Zingiberaceae family (Cardamom (Elettaria cardamomum), Ginger (Zingiber officinale)), Citrus oils (Grapefruit (Citrus x paradisi), Mandarin (Citrus reticulata)) and florals (Cananga odorata Complete, Pelargonium graveolens, Rosa spp.)
