Mother’s milk tea is an herbal tea marketed primarily to breastfeeding parents who want to increase their milk supply. The most popular version, made by Traditional Medicinals, contains fenugreek, fennel, anise, coriander, and blessed thistle, all herbs with a long history of use as galactagogues (substances believed to promote lactation). Whether the tea reliably delivers on that promise is more complicated than the packaging suggests, but it does appear to be safe for both mothers and infants, and some of its ingredients carry secondary benefits worth knowing about.
Lactation Support: What the Evidence Shows
The primary reason people buy this tea is to boost breast milk production. Fenugreek, the lead ingredient, is one of the most commonly used herbal galactagogues worldwide, and many women report that it works quickly. The active compounds in fenugreek include trigonelline, 4-hydroxyisoleucine, and sotolon, but the Academy of Breastfeeding Medicine notes that the actual mechanism by which any of these might increase milk supply remains unknown. Their clinical protocol on galactagogues describes the evidence for fenugreek as “insufficient” and flags a likely significant placebo effect.
That doesn’t mean the tea is useless. Placebo effects are real physiological events, and for something like lactation, where stress and anxiety can directly suppress milk output, the ritual of sitting down with a warm cup of tea several times a day may itself be therapeutic. The act of hydrating more frequently also helps. Many breastfeeding parents find the tea works for them, and the anecdotal reports are widespread enough that lactation consultants frequently recommend it as a low-risk first step.
A randomized, double-blind controlled study published in the Journal of Human Lactation tested the safety profile of Mother’s Milk tea specifically. No adverse effects attributable to the tea were reported at any point during the study, in either mothers or infants. Digestive, respiratory, and skin-related symptoms were the same in the tea group and the control group. The study focused on safety rather than efficacy, so it doesn’t give us a clean percentage increase in milk volume, but it does confirm the tea isn’t causing harm.
Fennel and Infant Colic
Fennel, the second key ingredient, has been studied separately for its effects on infant colic. A systematic review and meta-analysis published in the International Journal of Pediatrics found that fennel, particularly in combination with other herbal ingredients, significantly reduced crying time in colicky infants compared to controls. In one of the reviewed trials, 65% of infants treated with a fennel oil preparation saw their colic resolve, compared to just 24% in the placebo group. Another trial using an herbal tea containing fennel found colic eliminated in 57% of infants versus 26% on placebo.
The connection to mother’s milk tea is indirect. When a breastfeeding parent drinks the tea, small amounts of fennel compounds pass into the breast milk. Whether the concentration is high enough to produce a meaningful antispasmodic effect in the infant’s gut isn’t well established, but some parents report that their babies seem less gassy after they start drinking the tea. It’s plausible, given fennel’s documented effects, though not proven at the doses present in a cup of tea.
How to Prepare and Use It
Traditional Medicinals recommends steeping one tea bag in 8 ounces of freshly boiled water for 10 to 15 minutes, covered. That steeping time is longer than most teas and matters for extracting the herbal compounds. The recommended intake is 3 to 5 cups per day, though the packaging also lists a more conservative range of 1 to 3 cups daily to support healthy lactation.
Most women who notice an effect report it within the first few days. Fenugreek in particular has a reputation for working quickly. If you’ve been drinking 3 to 5 cups a day for a week with no noticeable change, the tea alone probably isn’t going to solve the problem, and it’s worth looking at other factors like latch, feeding frequency, and overall hydration. The tea works best as one piece of a broader approach to milk supply, not a standalone fix.
Side Effects and Safety
The clinical trial data on Mother’s Milk tea is reassuring. In the Journal of Human Lactation study, adverse event rates were identical between the tea group and the placebo group for both mothers and infants. Four participants left the study over concerns about possible side effects, but a blinded physician reviewed each case and found the events were mild and could not be linked to the tea.
That said, fenugreek in larger doses (supplements rather than tea) can cause a few notable effects. It’s known to give your sweat and urine a maple syrup-like odor, which is harmless but can be startling. Some people experience mild digestive upset. The tea delivers a lower dose of fenugreek than capsule supplements do, so these effects are less common with the tea alone.
Who Should Be Cautious
Fenugreek is not safe during pregnancy in amounts greater than what you’d find in food. The National Institutes of Health notes that higher doses have been linked to increased risks of birth defects in both animal and human studies. This tea is designed for postpartum use, not prenatal.
If you have diabetes or take medication to lower your blood sugar, fenugreek deserves extra caution. Large doses can cause a harmful drop in blood sugar. The amount in a few cups of tea is relatively small, but if you’re already on blood sugar-lowering medication, the combined effect could be a problem. Fenugreek can also trigger allergic reactions, including serious ones, particularly in people who are allergic to peanuts or chickpeas (they’re in the same plant family). And if you take any prescription medication, it’s worth checking for interactions before adding the tea to your routine, as fenugreek can interfere with how certain drugs are absorbed.
One honest note from the NIH: “Little is known about whether it’s safe to use fenugreek in amounts greater than those found in food while breastfeeding.” The clinical trial on the tea itself found no safety signals, which is encouraging, but the broader evidence base on fenugreek and breastfeeding remains thin.
What the Tea Realistically Offers
Mother’s milk tea is a low-risk, mildly effective tool for breastfeeding support. It’s safe for most nursing parents and their infants. Its ingredients have plausible but not conclusively proven effects on milk supply, and the fennel component may offer modest digestive benefits for both mother and baby. The daily ritual of drinking several cups also encourages hydration and brief moments of rest, both of which genuinely support lactation.
Where it falls short is as a reliable, evidence-based treatment for low milk supply. If you’re dealing with a significant supply issue, the tea is unlikely to solve it on its own. It works best as a complement to frequent nursing or pumping, proper latch technique, adequate calorie and fluid intake, and, if needed, guidance from a lactation consultant.
