Sweet Fennel Essential Oil
Sweet Fennel Essential Oil contains approximately 70-80% trans-Anethole (an ether) and is known for its ability to assist with digestive and menstrual concerns and for its diuretic, mucolytic and expectorant properties. Please refer to the Uses section below for more possible applications.
Emotionally, Fennel Essential Oil can be helpful in blends intended to help provide mental stimulation, clarity and focus. Robbi Zeck writes that "The sweetness of Fennel assists in completing things that are unfinished or requiring further attention in your life... Fennel keeps your mind concentrated on a particular direction and accesses the quiet containment of continuity." [Robbi Zeck, ND, The Blossoming Heart: Aromatherapy for Healing and Transformation (Victoria, Australia: Aroma Tours, 2008), 79.]
It has been said by some that Fennel Essential Oil can help balance fluid retention and may help curb the appetite, and therefore, may be helpful in inhalation blends to support weight loss.
Aromatically, Fennel Essential Oil is sweet, yet somewhat spicy and peppery with a licorice-like (Anise) note. It is a top to middle note and is sometimes used within natural fragrancing. It blends well with essential oils in the wood, citrus, spice and mint families.
Due to its trans-Anethole content, Sweet Fennel Essential Oil requires careful use (as do all essential oils). See the Safety Information section below for more information.

Tisserand and Young indicate that Fennel Oil may interact with medication, and that it may inhibit blood clotting. They precaution to avoid use of the oil topically if it has oxidized as skin sensitization is more likely. Their contraindications include pregnancy, breastfeeding, endometriosis, estrogen-dependent cancers, and children under 5. Their dermal maximum is 2.5%. Reading Tisserand and Young's full profile is recommended. [Robert Tisserand and Rodney Young, Essential Oil Safety (Second Edition. United Kingdom: Churchill Livingstone Elsevier, 2014), 277.]
