What’s in the popular breastfeeding tea, what the evidence says about milk supply, who should avoid fenugreek, and what helps supply more.
Mother’s milk tea is an herbal tea sold to support breast milk supply. The best-known version is Traditional Medicinals’ Organic Mother’s Milk, a caffeine-free blend of fennel, anise, coriander, fenugreek and blessed thistle. Does it work? Some mothers feel it helps, but there’s no good evidence that it reliably raises milk supply. Is it safe? For most breastfeeding mothers, drinking it as the package directs is unlikely to cause harm, but fenugreek isn’t right for everyone. Frequent milk removal does far more for supply than any tea.
What’s in mother’s milk tea?
According to the U.S. label, Organic Mother’s Milk contains:
- Fennel and anise: seeds with a sweet, licorice-like taste, used for milk in European folk tradition
- Coriander: a culinary seed
- Fenugreek: the best-known “milk herb”
- Blessed thistle: a bitter herb traditionally paired with fenugreek
- Spearmint, lemongrass and lemon verbena for flavor
Other brands sell their own “milk” or “lactation” teas with different herbs and amounts, so always read the full label.
Does mother’s milk tea work?
The honest answer is: it isn’t proven. The herbs have been used for generations, and a few small studies have looked at fenugreek and fennel, with mixed results. There aren’t good-quality trials showing that the tea reliably increases milk supply.
Why might some mothers notice a difference? A warm drink can be relaxing, which can help milk flow, and mothers trying the tea often start feeding or pumping more at the same time, which does raise supply. Neither means the herbs themselves did the work.
If you enjoy it and it suits you, it’s a reasonable addition. It just shouldn’t replace the steps that matter most; see How to Increase Milk Supply, and What Doesn’t Help.
Is mother’s milk tea safe?
Drunk as the package directs, it’s generally considered low risk for most healthy breastfeeding mothers. The main concerns come from fenugreek. Talk to your clinician first if you:
- Have diabetes or take medicine that lowers blood sugar, since fenugreek can lower it too
- Take a blood thinner or have a bleeding disorder
- Have asthma
- Are allergic to peanuts, chickpeas or other legumes, which are related to fenugreek
- Are pregnant. These teas are meant for after birth, and the label advises checking with your practitioner.
- Have a baby who is premature or has health problems
Possible side effects
- A maple-syrup smell in your sweat or urine, and sometimes your baby’s. It’s harmless from fenugreek, but tell your baby’s doctor so it isn’t confused with a rare metabolic condition.
- Gas, loose stools or an upset stomach in you, and possibly fussiness or gas in your baby
- Allergic reactions: rash, itching or, rarely, swelling or wheezing. Stop and get urgent help for any trouble breathing.
More isn’t better. Drinking large amounts of herbal blends containing fennel and anise has been linked to illness in breastfed newborns. Stick to the package directions, don’t combine several milk teas or supplements, and stop if your baby seems unwell. For a full safety checklist, see Lactation Pills: Side Effects and Safety.
If you decide to try it
- Follow the package directions for steeping and daily amount
- Start one new product at a time, so you can tell what causes any reaction
- Keep feeding or pumping often; that’s what drives supply
- Watch your baby for rash, unusual fussiness, diarrhea or sleepiness
- Judge results by your baby’s diapers and weight, not how full you feel; see Signs of Low Milk Supply
What helps milk supply more
Feeding or pumping 8 to 12 times a day, a good latch and pump fit, skin-to-skin contact, and a short power pumping plan do far more than any tea. Eating enough matters too; see Foods That Increase Milk Supply. An International Board Certified Lactation Consultant (IBCLC) can find what’s holding supply back.
Call your baby’s doctor promptly if your baby has fewer wet diapers than expected, isn’t gaining weight, looks more yellow, or is unusually sleepy.
Where Breastfeeding Support fits
Some mothers prefer not to add another tea or capsule. The Breastfeeding Support herbal pouch is a sealed external pouch, worn over the navel, or at the lower back after a cesarean birth, with nothing to swallow. It’s a traditional wellness routine to use alongside your feeding plan, not a treatment for low milk supply. Wearing it doesn’t prove its herbs can’t be absorbed, and breastfeeding safety studies haven’t been done, so review the ingredients with your clinician, and keep pouches away from your baby.
Quick answers
How fast does mother’s milk tea work?
There’s no reliable timeline because the effect isn’t proven. Changes from more frequent feeding usually show within a few days.
Can I drink mother’s milk tea while pregnant?
Ask your clinician first. Fenugreek in large amounts may affect the uterus, and these teas are designed for after birth.
Does mother’s milk tea have caffeine?
No. Organic Mother’s Milk is caffeine-free.
Can mother’s milk tea cause gas in babies?
It’s possible. If your baby seems uncomfortable after you start it, stop and see if things improve.
