What is fennel?

Fennel has a white bulb, green stalks, and dill-like leaves with a fresh anise flavour. Fennel is classed as a spice, herb and a vegetable and is used in various cuisines for its flavour. It is also known for its potential health benefits, including digestive aid properties[i].

What are the benefits of fennel in the diet or taking fennel supplementally?

Fennel is used for various digestive problems including heartburn, gas, bloating, colic in babies and more[ii]. Fennel seeds are seen to have antioxidant, anti-inflammatory, anti-fungal, and antiviral effects[iii][iv][v].

IBS (Irritable Bowel Syndrome) and gas

Fennel may be helpful for people with IBS since it can help relieve gas - it was seen to reduce pain in the abdomen in IBS studies[vi].


Due to the anti-inflammatory benefits of fennel, it may help soothe swelling or irritation in the intestines and improve digestion. As such, stomach pain, over-fullness and bloating during and after eating may be improved with fennel[vii][viii].


Fennel seeds may also relax muscles in the intestines, which can help relieve constipation[ix].

Colic in babies

As a young baby's digestive system isn't fully developed, they may feel discomfort related to digestion. Fennel is an excellent herb for children/ infants with colic [x][xi]

Menstrual cramps (dysmenorrhea)

It is thought that fennel may help to reduce period cramps by lowering the level of prostaglandins in blood circulation. Prostaglandins are hormone-like substances that narrow blood vessels and cause inflammation, which can cause swelling into the surrounding tissues[xii].

Menopause symptoms

Fennel contains essential oils which may produce oestrogen mimicking effects, known as phytoestrogenic properties. Therefore phytoestrogens, such as those in fennel, have been used to effectively treat a wide array of menopause symptoms[xiii][xiv]. It has also shown some potential benefits in improving sleep quality issues in the menopause[xv].


Caution during pregnancy

It is advised to avoid using fennel as it may pose potential risks, including a potential link to preterm birth when used regularly.


In small amounts, fennel can benefit infants with colic (via breastmilk). Therefore, smaller amounts in breastmilk are likely not to be harmful with usual maternal doses.
