At The Breastfeeding Tea Co, we understand that as a breastfeeding mum, you’re mindful of every ingredient that goes into your body—because you know it can impact both you and your baby. One question we’re often asked is: “Is fennel safe when breastfeeding?”

The short answer is yes—absolutely! When consumed in safe amounts, fennel is not only safe but incredibly beneficial for breastfeeding mothers. In fact, it’s one of the most well-researched herbal galactagogues (a natural substance that supports milk supply).

Let’s take a closer look at why fennel is so loved by breastfeeding mums, and why we’ve chosen to include it in our lactation blends.

What is Fennel?

Fennel (Foeniculum vulgare) is a flowering plant in the carrot family, known for its sweet, anise-like flavour. Both the seeds and the essential oil have been used traditionally for centuries to help ease digestion, reduce bloating, and—most importantly for new mums—support breast milk production.

Fennel and Breast Milk Supply

Fennel contains anethole, a compound that mimics the hormone estrogen, which plays a role in stimulating milk production. This is why fennel has been a key ingredient in traditional lactation remedies around the world.

Modern research supports this: studies have shown that fennel may increase milk volume, improve milk fat content, and even help babies gain weight more steadily.

Wait.. So Is It Safe for Baby when breastfeeding?

Yes. When consumed in normal food or tea amounts, fennel is safe for both mum and baby. At The Breastfeeding Tea Co, we use carefully measured doses of organic fennel to ensure you get the benefits without any risk of overconsumption.

Some mums even notice that their baby seems less gassy or colicky after drinking our teas containing fennel—thanks to its gentle digestive properties that may pass through breast milk.

What About the Warnings Online?

If you’ve seen conflicting information about fennel, you’re not alone. Like with many herbs, safety depends on the dose and form. Fennel essential oil in high concentrations is not recommended internally, especially while breastfeeding.

But rest assured, the brewed seed form found in our teas is completely safe, as confirmed by herbalists and lactation experts around the world.
