Most mothers who drink Mother’s Milk tea consistently notice a change in their milk supply within 24 to 72 hours, though for some it can take up to a full week. The key word is “consistently.” Drinking one cup and waiting for results isn’t how this tea works. The manufacturer recommends 3 to 5 cups per day, steeped for 10 to 15 minutes with a cover on the mug to keep the volatile oils from evaporating.
What’s in the Tea
The most popular version, made by Traditional Medicinals, contains nine botanical ingredients: fennel, anise, coriander, fenugreek seed, blessed thistle, spearmint leaf, lemongrass, lemon verbena, and marshmallow root. Fenugreek and fennel are the two that get the most attention as potential milk boosters. They belong to a category called galactagogues, substances believed to stimulate milk production. Fenugreek in particular has a long history of traditional use and is the ingredient most often studied in clinical trials.
What the Research Actually Shows
The evidence is mixed. A large meta-analysis of randomized controlled trials found that herbal galactagogues as a group were associated with a meaningful increase in total milk volume and higher levels of prolactin (the hormone that drives milk production) compared to placebo. That sounds promising, but the Academy of Breastfeeding Medicine still does not recommend any specific galactagogue, herbal or pharmaceutical, because the overall body of research remains inconclusive and the quality of individual studies varies widely.
That doesn’t mean the tea is useless. It means the scientific community hasn’t pinned down exactly how much it helps, for whom, or whether the benefit comes from the herbs themselves or from the extra fluid intake, the relaxation ritual of drinking warm tea, or the psychological boost of feeling like you’re doing something proactive. All of those factors can genuinely support milk production on their own.
Safety for You and Your Baby
A double-blind, randomized controlled trial published in the Journal of Human Lactation followed healthy, exclusively breastfeeding mothers and their infants over 30 days, then checked in again at 3, 6, 9, and 12 months. No adverse effects were linked to the tea at any point. Digestive symptoms, respiratory symptoms, skin reactions, and breast-related issues like engorgement occurred at the same rate in both the tea group and the placebo group. No serious adverse events were reported in mothers or infants throughout the entire study period.
The most commonly reported “side effect” outside of clinical settings is a maple syrup smell in sweat and urine, which comes from fenugreek. It’s harmless and disappears once you stop drinking the tea. Some mothers also report mild gas or loose stools, either in themselves or their babies, though the clinical trial data didn’t find a statistical difference between tea and placebo groups for digestive complaints.
How to Tell If It’s Working
You won’t feel a dramatic surge. The changes are gradual, and the most reliable way to gauge progress is by watching your baby rather than your breasts. Signs that your supply is adequate or increasing include:
- Wet diapers: At least 6 wet diapers in 24 hours from day five onward.
- Stool changes: After the first week, at least 2 soft yellow stools per day.
- Feeding rhythm: Your baby starts with a few quick sucks, then settles into long, rhythmic sucks with audible swallowing. Their cheeks stay rounded rather than hollowing inward.
- Post-feed behavior: Your baby releases the breast on their own and seems calm and satisfied afterward.
- Breast feel: Your breasts feel noticeably softer after a feeding session.
- Weight gain: Steady weight gain after the first two weeks of life.
If you’re pumping, you can track output more directly. Compare your totals over several days rather than looking at a single session, since milk production fluctuates throughout the day.
Getting the Most Out of It
Steep each bag in 8 ounces of freshly boiled water for 10 to 15 minutes with a cover over the cup. This matters because the active compounds in fennel and anise are in the essential oils, which evaporate with the steam if you leave the cup uncovered. Drink 3 to 5 cups spread throughout the day, not all at once.
The tea works best as one piece of a larger strategy. Frequent nursing or pumping is the single strongest signal your body uses to calibrate milk production. Skin-to-skin contact, adequate hydration, calorie intake, and sleep all play a role too. If your supply hasn’t improved after a week of consistent tea use alongside frequent feeding, the issue may be something a lactation consultant can help identify, like a shallow latch or an inefficient pump flange size, rather than something an herbal tea can fix.
