Fennel Fruit Essential Oil
Also known as: Bitter fennel, Carosella, Common fennel, Finocchio, Florence fennel, Garden fennel, Large fennel, Sweet fennel, Wild fennel, Foeniculum vulgare
Overview
Fennel (*Foeniculum vulgare*) is an aromatic herbaceous plant belonging to the Apiaceae family, widely known for its culinary and medicinal applications. The essential oil, extracted from the seeds of fennel through steam distillation, contains volatile compounds such as trans-anethole, fenchone, estragole, and limonene. Traditionally, fennel oil has been used as a flavoring agent, insect repellent, and herbal remedy for gastrointestinal ailments, menstrual abnormalities, and postmenopausal issues. Current research indicates moderate support for its therapeutic effects, particularly in women experiencing premenstrual syndrome (PMS) and menopausal symptoms, although the body of clinical studies remains limited and calls for more comprehensive systematic reviews.
Benefits
Fennel essential oil is recognized for several evidence-based benefits: 1) **Menstrual Symptoms**: Demonstrated effectiveness in alleviating PMS symptoms, including anxiety and depression, with one study showing a significant reduction (p < 0.05) when using 60 drops of 2% oil daily. 2) **Dysmenorrhea**: Reduced menstrual pain severity significantly (p < 0.05) with 20 drops taken every 8 hours. 3) **Postmenopausal Symptoms**: Improved quality of life and symptomatology in menopausal women in a study yielding p < 0.001. Additionally, it exhibits **Gastrointestinal Health** benefits due to its carminative properties and potential antioxidant and anti-inflammatory effects.
How it works
Fennel oil's actions are primarily linked to its bioactive components, especially trans-anethole, which shows anti-inflammatory and antioxidant properties. The oil modulates gastrointestinal function by relaxing smooth muscles and reducing contraction frequency, thereby alleviating discomfort and gas. Its estrogenic activity may account for its efficacy in treating menstrual and postmenopausal symptoms, interacting with hormonal pathways to alleviate discomfort.
Side effects
Fennel oil is generally safe when used as directed, yet it may cause adverse effects in some individuals. Common side effects include bad taste (70% of users) and gastrointestinal discomfort. Uncommon side effects (<5%) encompass contact dermatitis and photodermatitis, while rare adverse effects (<1%) could include hallucinations and seizures from high doses. Additionally, fennel may interact with drugs metabolized via the cytochrome P450 3A4 pathway. Pregnant and lactating women, as well as children, should avoid fennel oil due to potential adverse reactions. Overall, caution is advised with special populations due to these risks.
Dosage
The minimum effective dose for PMS is recommended at 60 drops of 2% fennel oil per day, whereas for dysmenorrhea, 20 drops every 8 hours is suggested. The optimal dosage for fennel oil in oral capsules typically ranges from 200 mg per day. Timing considerations entail taking the oil approximately three days prior to and during the menstrual period. Fennel oil can also be administrated in other forms, such as drops or creams, which vary in bioavailability; however, the general absorption is favorable across these forms.
