How to use fennel essential oil?

With this very specific aniseed odour, its component anethol is also used in the manufacturing of spirits in the South of France and it reminds people of cicadas and the singing sound of the speech of the local people.

All well and good, but the fennel essential oil is one of the EOs to handle with care.

 

Botanic characteristics

Very highly appreciated in food for its aniseed flavour, fennel is a common vegetable that is found in India, Japan, central Europe and all around the Mediterranean.

It is a tall perennial plant that reaches a height of 1 to 2 m with:

  • Long stems closely tightened at the base within a large sheath.
  • Dark green leaves, finely chiselled in the shape of strips.
  • Yellow flowers in bunches and small greenish fruit.
  • Leaves and fruit have an aniseed perfume.

The EO of fennel is a yellowish liquid, slightly viscous that is obtained by extraction from the grains.

 

Yield: 100kgs of grains produce 2 to 6 kgs of EO

Composition of sweet fennel EO (seeds)

  • Ethers: trans-anethol (75-90%),methyl-chavicol (Estragol, Trans Anethol)
  • Monoterpenes (8 à 15%): limonene, alpha-pinene, alpha-phellandrene
  • Ketones monoterpenics: Fenchone (1-5%) No more than 7 days in a row
  • Furocoumarines: traces

Let us make it clear, we are talking here about sweet fennel (Foeniculum vulgare variety dulce). There is also a bitter fennel (vulgare) with more ketones and less trans-anethol (overall much less tolerated).

Properties of sweet fennel EO

Despite the necessary precautions that need to be taken, sweet fennel EO has very interesting properties:

Actions of trans-anethol

  • Stimulates breastfeeding +++: by mimicking the action of estrogen it enhances the production of maternal milk
  • Antispasmodic +++: fights digestive or respiratory muscular spasms. It soothes involuntary contractions.
  • Relieves digestive troubles +++: stimulates saliva, gastric, intestinal and pancreatic secretions.

 

Actions of ketones

  • Nervous, respiratory and cardiac tonic +++ 
  • Analgesic ++: alleviates pain.

 

Action of phenols methyl-ethers

  • Anti-inflammatory ++: soothes sensations of heat and redness

 

Action of monoterpenes

  • Respiratory tonic++: the stimulation by alpha pinene provokes a sensation of clearing of the respiratory tract.

Indications and route of administration of sweet fennel EO

Atmospheric route

It is not an EO that can be diffused or inhaled (because of the neurotoxic ketones).

Dermal route

This route remains interesting, even though this EO can be irritating. It can be useful in massage on the stomach in the case of:

  • Gas and spasms
  • Flatulence, hiccup, nausea, colitis, constipation
  • Crohn’s disease symptoms and inflammatory colitis
  • Painful or irregular periods, absence of periods.
  • Its antispasmodic properties can also be a help in the case of rheumatism, lumbar or muscular pain.

Oral route

It is the most appropriate route for this EO (even in the kitchen)

It acts on digestive problems, problems of lactation, painful periods and the menopausal syndrome.

The maximal usage is 3 times a day / 1 drop of a carrier (honey or a vegetable oil for example. Leaving it in the mouth under the tongue for a few seconds).

In cooking, sweet fennel EO can bring an added flavour in desserts for example. Dilute the EO (2 drops will flavour a dish) in an oily substance (oil or butter for example) or some dispersant before incorporating it in the dish.

precautions

Dangers et counter-indications of sweet fennel EO

Sweet fennel EO should be used in moderation as its usage in high doses could provoke convulsions.

It is not recommended for:

– children under the age of 8 and pregnant women.

– people suffering from a hormonal cancer (breast, uterus) or suffering from antecedents.

– people suffering from hypothyroid (it blocks the activity of the thyroid).

It is:

– an irritant to the skin: therefore it should always be applied when diluted in a VO.

– potentially photo-sensitive (presence of furocoumarines)

neurotoxic (presence of ketones)

oestrogen-like: strong influence on the hormonal system (strong concentration in anethol). As a result it is forbidden by dermal route below the abdominal belt in pregnant women.

This is indeed a lot of precautions listed but this EO remains very useful for all woman problems if it is used carefully and for a short duration.

Weary to try? Eat some fennel J. It is a milder way of using it especially for digestion and lactation.
