Mother’s Milk tea is a herbal tea marketed to breastfeeding women to help increase milk supply. The most widely known version is made by Traditional Medicinals, though several brands now sell similar blends. It contains a mix of herbs long used as galactagogues, substances believed to promote lactation, with fenugreek and fennel as the primary active ingredients.
What’s in the Tea
The core ingredient in most Mother’s Milk tea blends is fenugreek, a plant whose seeds contain active compounds including trigonelline, 4-hydroxyisoleucine, and sotolon. Alongside fenugreek, the tea typically includes fennel seed, anise seed, coriander, and blessed thistle. These herbs have been used in folk medicine traditions across cultures for centuries to support milk production, though they’ve only recently attracted formal scientific attention.
The tea also contains licorice root, which contributes to the flavor and adds a mild natural sweetness. Some formulations include spearmint or lemongrass to round out the taste.
What It Tastes Like
The dominant flavor is licorice, thanks to the combination of licorice root, fennel, and anise. Many people describe it as moderately sweet with warm, spiced notes similar to chai. If you enjoy licorice or anise flavors, you’ll likely find it pleasant. If those flavors aren’t your thing, adding honey or mixing it with another tea can help.
How It’s Supposed to Work
The honest answer is that scientists don’t fully understand how herbal galactagogues increase milk production. Prescription medications used for the same purpose work by blocking dopamine, which raises prolactin levels (the hormone that drives milk production). But herbal ingredients like fenugreek don’t appear to work the same way, and the Academy of Breastfeeding Medicine notes that the mechanisms of action for most herbal galactagogues remain unknown.
What researchers do know is that fenugreek contains plant compounds that mimic estrogen to some degree, which may play a role. Some researchers also suspect that the simple act of drinking warm fluids regularly, combined with the relaxation ritual of tea, could itself support the hormonal conditions that favor letdown and milk flow.
Does It Actually Increase Milk Supply?
The evidence is mixed but cautiously promising. Clinical trials on herbal lactation teas have shown measurable increases in milk volume, though the studies tend to be small. One randomized controlled trial published in PLOS ONE found that women drinking herbal lactation tea produced an average of 57.5 mL per expression at 72 hours postpartum, compared to 31.9 mL in the placebo group. Notably, the herbal tea group’s output was statistically indistinguishable from a group taking domperidone, a prescription medication commonly used to boost milk supply.
That said, the Academy of Breastfeeding Medicine cautions that the body of research on herbal galactagogues suffers from small sample sizes, inconsistent methods, and a lack of proper controls or blinding. Many women report that fenugreek-based teas helped them, but separating the herbal effect from placebo response, improved hydration, and better breastfeeding habits remains difficult. The tea is unlikely to overcome significant supply issues caused by underlying medical conditions, hormonal imbalances, or insufficient breast stimulation.
How to Prepare and Use It
For the best extraction of the active herbal compounds, steep one tea bag in 8 ounces of hot water for at least 5 minutes. Most sources recommend starting with one to two cups per day and gradually increasing to three cups daily if you tolerate it well. Drinking it consistently matters more than drinking large amounts at once.
Many women report noticing changes in supply within 24 to 72 hours of regular use, though individual responses vary widely. If you don’t see a difference after a week of consistent use, the tea is unlikely to be effective for you.
Side Effects to Know About
Fenugreek is generally well tolerated at the doses found in tea, but it’s not risk-free. The most common side effects include gastrointestinal discomfort, bloating, gas, and diarrhea. These tend to be mild but can be bothersome, especially in the early postpartum period.
One quirky but harmless effect: fenugreek has a strong maple syrup flavor, and women who take it regularly often notice that their sweat, urine, or even their baby’s urine takes on a distinct maple syrup scent. This is not dangerous, just surprising if you’re not expecting it.
More serious concerns exist for specific groups. Large doses of fenugreek can cause a harmful drop in blood sugar, which is particularly important for women managing diabetes. Fenugreek can also trigger allergic reactions, including severe ones, in some people, especially those with allergies to peanuts or chickpeas (they’re in the same plant family). And while the tea is designed for postpartum use, fenugreek in amounts greater than normal food quantities is not safe during pregnancy. The National Center for Complementary and Integrative Health reports that its use has been linked to increased risks of birth defects in both animal and human studies.
Safety data on how fenugreek affects a nursing infant through breast milk is sparse. Researchers at the MGH Center for Women’s Mental Health note that there is very limited information on the impact fenugreek supplements may have on a developing infant.
Who It’s Best Suited For
Mother’s Milk tea works best as one tool among many for women experiencing mild dips in supply, particularly during growth spurts, return to work, or periods of stress. It pairs well with the fundamentals of milk production: frequent nursing or pumping, adequate hydration, calorie intake, and rest. It’s not a substitute for those basics, and it’s not a solution for anatomical or hormonal causes of low supply.
If you’re taking medications for diabetes, blood thinners, or thyroid conditions, check with your provider before adding fenugreek-based products. Some herbs interact with medications in ways that can alter drug absorption or effectiveness. Women with a history of hormone-sensitive conditions should also use caution, given fenugreek’s mild estrogenic properties.
