Sweet Fennel commonly used in kitchen Sweet Fennel oil is used to enhance the flavours of confectionary and we are aware of some medicinal properties as well, Sweet Fennel essential oil obtain by steam distillation. Fennel sweet essential oil can attributed to its properties as an antiseptic, antispasmodic, aperitif, carminative, depurative, diuretic, emmenagogue, expectorant, galactagogue, laxative, stimulant, stomachic, splenic, tonic and vermifuge substance. It is also used for cosmetic purposes, especially as an ingredient in massage oils perfumes, toothpastes and soaps.
Fennel is native to southern Europe and the Mediterranean area. The name comes from the Greek word for "marathon" because the famous battle at Marathon (490 BC) against the Persians was fought on a field of Fennel. Pliny said that snakes casting off their skins ate Fennel to restore their eyesight.
Fennel seeds were extracted steam distillation with supercritical carbon dioxide. Small-scale subsequent extractions of the same sample showed that the composition of volatile compounds was changed with the extension of extraction time and only principal volatile components were present in the last-extracted sample. Fennel oil was successfully fractionated into the essential oil rich and fatty oil rich products in pilot-scale apparatus using two separators in series.

An organic component called Trans Anethole, which present in fennel essential oil, boosts the production of the estrogen hormone. Although this is beneficial for lactating mothers, it is harmful for pregnant women and women with breast cancer or uterine cancer or tumor, since excess estrogen is the main cause of such cancers. In heavy doses, it may have narcotic effects and can result in convulsions, hallucinations and mental imbalance. People suffering from epilepsy or with a history of that condition should avoid using fennel essential oil.
Quality Sweet fennel oil may be adulterated with monoterpene hydrocarbons such as limonene, and with synthetic anethole, which usually contains the more toxic (Z)- isomer. Bitter fennel oil may be passed off as sweet fennel oil.
Hazards Drug interaction; reproductive hormone modulation; potentially carcinogenic, based on estragole content; may inhibit blood clotting; skin sensitization if oxidized.

The Commission E Monograph for fennel oil. recommends that it is not used in pregnancy, or “for infants and toddlers”. IFRA recommends a maximum dermal use level for estragole of 0.01% in leave-on or wash-off preparations for body and face. The EU does not restrict estragole.

- Cardiovascular effects
- Reproductive toxicity
- Acute toxicity
- Antioxidant/pro-oxidant activity
- Carcinogenic/anticarcinogenic potential
Both (þ)-limonene and fennel oil induce glutathione synthesis, and (þ)-limonene is anticarcinogenic while estragole is carcinogenic. In the absence of any further information, sweet fennel oil should be treated as a potential carcinogen, because of its estragole content. There are four chemotypes of fennel, an anethole, a (þ)-limonene, an estragole and an estragole/fenchone, although only the anethole chemotype is used for commercial essential oil production. In an analysis of 30 anethole chemotype oils, the estragole content ranged from 2.0–4.3%. Anisaldehyde, an oxidation product of anethole, increases if the oil is improperly stored.
