Using Fennel While Breastfeeding

Fennel is a Mediterranean herb with yellow flowers, feathery leaves, and a pleasant smell. It’s commonly used for flavoring purposes, but this herb has a lot of hidden value.

Fennel has similar properties to the hormone estrogens (Phytoestrogens); thus, it’s considered a galactagogue.  A galactagogue is a food or drug that promotes or increases the flow of a mother's milk.

Breastfeeding Mothers Use Fennel for...

Fennel has been used for many purposes over the years but is known for the following in breastfeeding communities.

  • Increasing breast milk supply.
  • Colic in breastfed infants (Fennel seed oil can be used for infants from 2 weeks) Before two weeks of age, the baby can still benefit because the active ingredients in Fennel pass through breast milk and help to relieve colic and gas symptoms in the baby.
  • Increase sex drive.
  • Reduce menstrual pains.
  • One small study found an increase in the fat content of breast milk when Fennel was introduced into the mother's diet.
  • Many mothers have used a warm infusion of fennel seeds and marshmallow root to immerse the breast in, to treat breast inflammation.

‌‌How Can You Use Fennel?‌‌

As a Supplement

It is always best to consume Fennel in its natural form. Over-the-counter Fennel supplements may contain other added ingredients that are not always safe. This is because dietary supplements do not require extensive pre-marketing approval from the US Food and Drug Administration.

Applied Topically - Fennel Essential Oil for Breastfeeding

Fennel essential oil can be placed topically on the breast's skin to increase milk supply! Fennel oil can be placed neat (without dilution) on the skin, but for easy application, you can mix 15 drops of Fennel oil in a tbsp of coconut oil. Apply a small amount around the breast (not on the nipple). Do this AFTER a breastfeeding session. Do not use this for longer than ten days without breaks in between.

‌‌Fennel Tea‌‌

Take two cups of water and add one of the following:

  1. Use 1 to 2 teaspoons of fennel seeds. Crush the seeds slightly to promote the volatile oils to be released.
  2. The fennel leaves can also be used to make tea. Chop the leaves into large pieces to promote the oil release.
  3. 1 to 2 teaspoons of chopped fennel root is also easy to brew tea with. The root's texture can cause the brewing time to be a bit longer.

‌You can add more ingredients to suit your taste buds. Honey and lemon are always pleasant with tea.

Let the tea sit for no longer than 10 minutes. The longer the tea sits, the more volatile compounds are released into the air and not your digestive system, thus minimizing its effects.

Add some juice to make a refreshing iced tea.

REMEMBER never to overheat the water, as it may destroy the essential components of the Fennel.

Fennel for breast milk boost - Drink 1 to 2 cups daily. Try one first and then increase if needed.
