Benefits of Fennel: Digestion and Natural Breastfeeding Support

Cycle comfort and painful periods

Fennel helps maintain a comfortable menstrual cycle, particularly by reducing pain. It also contributes to reducing the fatigue, nausea and anxiety often experienced during periods, to help you get through those days with greater calm.

Post-partum and breastfeeding support

In the post-partum period, fennel may help ease pain and reduce the intensity of bleeding after birth. And for breastfeeding mothers, good news: it naturally supports breast milk production, making it a doubly valuable plant in those first few weeks.

Everyday Digestive Comfort

Fennel supports healthy digestion, reduces bloating, and helps with elimination — three very practical benefits for women whose digestive transit tends to slow down in the premenstrual period or after giving birth.

Origin and description

Fennel (Foeniculum vulgare) is a perennial aromatic plant of the Apiaceae family, native to the Mediterranean basin and cultivated since antiquity for its culinary and medicinal properties.

Its seeds, leaves and root contain an essential oil rich in anethole, a compound with antispasmodic, digestive and mild phytoestrogenic properties that explain its action on the female cycle and lactation. Its relevance is particularly credible for supporting menstrual comfort, the post-partum period and breastfeeding — three stages where its benefits prove especially useful. The quality of the organic extract and its standardisation for anethole directly determine the consistency and effectiveness of its action.

In its natural form, fennel is first and foremost known as a vegetable and as a herb. The bulb can be eaten raw in salads or cooked by steaming, roasting or braising, whilst the dried seeds are used in cooking to flavour dishes, soups and breads. Infused in hot water, fennel seeds are one of the most common digestive herbal teas, consumed for centuries across Europe to relieve bloating and intestinal cramps. Other plants with similar benefits include green anise, caraway and lemon balm, often combined in traditional digestive herbal teas. The absorption of fennel's active compounds depends on the form of consumption — fresh or dried — the infusion time and the overall food matrix. Dietary intakes through food remain enjoyable but difficult to standardise according to individual needs.

As a supplement, Fennel is found primarily in the form of seed extract standardised for anethole, diluted essential oil, seed powder capsules, or incorporated into indulgent preparations designed for breastfeeding. It features notably in Jolly Mama's Milk Cookies, a gentle and enjoyable way to benefit from its properties every day, without constraints and with pleasure. To ensure a consistent active content, a standardised anethole extract is preferable to a simple raw plant powder. It is best to choose seeds of organic origin, free from pesticide residues, and to verify the absence of unnecessary additives. Fennel is naturally vegan and generally well tolerated in everyday use.

How does it work? (The science bit)

Fennel acts primarily through anethole, the key compound in its essential oil, which gives it both its antispasmodic properties and its action on the female hormonal sphere. Once ingested, anethole is absorbed at the digestive level and circulates through the body, where it can exert a relaxing effect on smooth muscle, particularly that of the uterus and digestive tract. This muscle relaxation contributes to reducing menstrual cramps and intestinal discomfort, two very common complaints around the menstrual period and in the post-partum period. Studies have suggested that fennel may act at a level comparable to certain non-steroidal anti-inflammatory drugs in reducing pain and bleeding after childbirth, making it a particularly valued natural option.

In terms of breastfeeding, the action of fennel on lactation is thought to be partly explained by the chemical structure of anethole, which is close to certain molecules with mild phyto-oestrogenic activity, and which may stimulate the production of prolactin, the hormone involved in milk production. This effect is gradual and gentle, and always works alongside regular feeding at the breast, which remains the primary condition for a well-established milk supply. In the Jolly Mama Milk Cookies range, fennel is combined with other galactagogue plants for a synergistic and comforting effect, to be enjoyed as a dedicated moment of self-care.

Yes, this is one of its best-documented uses in herbal medicine. Its antispasmodic properties contribute to relaxing the uterine muscles and reducing menstrual cramps. It also helps to ease the fatigue, nausea and anxiety that sometimes accompany periods, making those days a little easier to get through.

Fennel is a plant traditionally recognised for supporting lactation. Its effect on milk production is gradual and always works best alongside regular breastfeeding, which remains the primary lever for establishing and maintaining a good milk supply. You'll find it in Jolly Mama's cookies, designed to support breastfeeding mothers.

At the quantities typically found in herbal teas and supplements, fennel is generally very well tolerated. Excessive consumption may cause mild digestive discomfort in sensitive individuals. People who are allergic to plants in the Apiaceae family, such as celery or carrot, may experience cross-sensitivity and should exercise caution.

Fennel in culinary quantities is safe during pregnancy, but concentrated extracts and essential oils are not recommended during pregnancy as a precaution, due to the mild phyto-oestrogenic activity of anethole. Seek advice from a healthcare professional if you are pregnant, on hormonal or anticoagulant treatment, or if you have a known oestrogen-related condition.

Very well. It pairs naturally with caraway, lemon balm or verbena for a digestive and soothing effect, and with other recognised galactagogue plants. This is the thinking behind Jolly Mama's organic and vegan express cookie mix with chocolate chips, which combines fennel with other active ingredients for comprehensive support of lactation and the wellbeing of breastfeeding mothers.
