The Tradition Behind the Claim

Reviews of the plant trace the galactagogue use to classical Ayurvedic texts. A 2003 review lists it alongside gastric ulcers and dyspepsia as the uses "recommended in Ayurvedic texts," and a 2021 review of the plant's brain-related effects describes it as "widely used for its lactogenic properties." LactMed, the US National Library of Medicine's database on medicines and breastfeeding, records that it "has a long history of use as a galactagogue in India and is included in the official ayurvedic pharmacopeia for this use."

Shatavari is also often given, and studied, as one ingredient of multi-herb preparations. That point turns out to matter a great deal for the research, because a herb studied only inside a mixture cannot be credited with the mixture's effect.

Tradition also explains the name. In Sanskrit shata means "a hundred," and the name is usually read as "she who possesses a hundred husbands" — a reference to the root's standing as a tonic for women's fertility and vitality rather than to anything about milk.

How Milk Supply Works, Briefly

Milk production is driven mainly by two hormones. Prolactin, from the pituitary gland, tells the breast to make milk; oxytocin makes the milk flow out during a feed. Prolactin rises with frequent, effective feeding or pumping, and the amount of milk removed is one of the strongest signals for how much more is made. This site's lactation and oxytocin animation shows the loop.

Because of that loop, a 2012 review of galactagogues stressed that many ordinary factors influence supply, including maternal pain, illness, returning to work, anxiety and emotional stress, and its authors concluded that "nonpharmacologic recommendations should be exhausted before adding therapy." LactMed makes the same point in its own words: galactagogues "should never replace evaluation and counseling on modifiable factors that affect milk production."

Some prescription drugs raise prolactin as a side effect, and two of them, metoclopramide and domperidone, have been used off-label to boost milk. That gives one way to think about how a herb might work — and, as described further down, Shatavari has been compared head-to-head with metoclopramide in a different setting.

The 2025 Placebo-Controlled Trial

The clearest test so far was published in 2025 in the Journal of Obstetrics and Gynaecology. It was prospective, randomised, double-blind and placebo-controlled — the design best able to separate a real effect from expectation.

• Who: 120 women aged 20 to 40 who had given birth at 37 weeks or later, by uncomplicated vaginal or caesarean delivery, and who intended to breastfeed.
• What: 300 mg capsules of a Shatavari root extract, or identical placebo capsules, twice a day for 72 hours after birth.
• Main outcomes: time from the last feed to evident breast fullness, and total milk volume expressed at 72 hours.
• Completion: 113 women (57 Shatavari, 56 placebo); 3 and 4 respectively dropped out.

What it found

• Time to breast fullness was significantly shorter with Shatavari (p = 0.002).
• Milk volume at 72 hours was significantly higher (p < 0.001).
• Maternal satisfaction with lactation was higher: 52.63% against 25.00% (p = 0.008).
• Investigators rated maternal and infant well-being higher with Shatavari (80.70% against 64.29%).
• No adverse events occurred in either group, and adherence was high.

The authors concluded that the extract "improved the milk volume and maternal satisfaction about lactation." On its own terms, it is a positive trial.

Reading the Trial Carefully

A positive trial is not the same as a settled question. Several features limit how far this one reaches:

• Three days. The trial covered the first 72 hours after birth, when milk "comes in" for most women anyway. It did not follow the women to see whether they breastfed longer, whether babies gained more weight, or whether any effect lasted.
• Who was included. The women had uncomplicated deliveries and were not selected for low supply. Whether the result applies to mothers who are actually struggling — the people most likely to seek a galactagogue — is untested.
• One extract. The trial used one specific root extract at one dose. LactMed warns that "clinical testing results on one product may not be applicable to other products."
• Per-protocol analysis. The results reported in the abstract are for the 113 women who completed, rather than all 120 randomised.
• Overlapping authors. Several authors of this trial also appear on recent Shatavari menopause trials, including one from a medical-writing contract research organisation. The paper's abstract does not list a conflict-of-interest statement; the menopause trial by overlapping authors declares none. A body of evidence produced mostly by one network of researchers is more fragile than the same number of independent replications.

None of this makes the result wrong. It means the finding is a single, short trial waiting for independent confirmation.

The Older Studies: Mixed, and Often Mixtures

LactMed's summary of the earlier literature is that "results of many clinical studies on the galactogogue activity of wild asparagus are mixed," and that Shatavari "has been studied as part of an herbal mixture." It singles out two better studies: one "small, well-done study" in which serum prolactin and infant weight rose more with Shatavari than with placebo, and a controlled study in which mothers taking Shatavari had greater milk volumes and shorter times to breast fullness at 72 hours than mothers on placebo.

The 2012 review in the Annals of Pharmacotherapy searched PubMed and EMBASE through June 2012 for human studies of galactagogues available in the US, including Shatavari. Its conclusion: although anecdotal evidence encourages the use of metoclopramide, fenugreek, asparagus and milk thistle, "efficacy and safety data in the literature are lacking," and "more studies are needed."

A 2025 review of Shatavari and fertility describes the herb's potential to "improve breast milk quality and quantity," but it is a narrative review that also says "further comprehensive clinical studies are necessary to confirm its effects, establish safety profiles" — a fair summary of where the question still stands.

Mixtures, Goats and Why They Do Not Answer the Question

Much traditional use, and many older studies, give Shatavari in combination with other herbs. A trial of a mixture can show whether the mixture works; it cannot show which ingredient did the work, or whether any single herb would work alone. A 2007 review flagged exactly this gap: "an incomplete understanding about the interaction/synergy between Asparagus racemosus and other plant constituents in polyherbal formulations."

Animal studies show the same problem. In a 2023 study, lactating goats were fed a composite extract made from four plants — horse gram seeds, Shatavari root, rohitaka bark and pomegranate peel — at 20 grams per kilogram of diet for 70 days. Milk yield rose, as did milk protein and lactose. It is an interesting result for goat farmers, but with four plants in the feed it says nothing about Shatavari on its own, and nothing about women.

A Side Note: Stomach Emptying and Metoclopramide

One of the oldest human studies of Shatavari was not about milk at all. In 1990, pharmacologists in Mumbai compared it with metoclopramide — a drug that speeds stomach emptying and that has also been used to boost milk supply. Eight healthy male volunteers were studied in a crossover design.

The average stomach half-emptying time fell from about 160 minutes at baseline to about 101 minutes with Shatavari and about 85 minutes with metoclopramide; the two treatments did not differ significantly. The authors chose metoclopramide because Shatavari is used for dyspepsia.

It is tempting to link the two uses: metoclopramide raises prolactin, and Shatavari shared one of its gut effects. But no study in the evidence for this page has shown that Shatavari acts through the same mechanism, and eight men are not a basis for conclusions about breastfeeding women. The study is worth knowing mainly as an early sign that the root has measurable effects in people.

Safety for Mother and Baby

LactMed's assessment is that "the safety of wild asparagus has not been rigorously studied, but small clinical studies have found no adverse effects in mothers or their nursing infants." The 2025 trial adds 57 mothers with no adverse events over three days.

What has not been measured:

• How much, if any, of the root's compounds pass into breast milk.
• Effects in infants over weeks or months of maternal use.
• Effects in premature or unwell babies.
• Interactions with medicines commonly used after birth.

LactMed also notes that supplements do not need pre-marketing approval from the US Food and Drug Administration, and that "differences are often found between labeled and actual ingredients or their amounts." The 2025 fertility review states that it is crucial for pregnant and breastfeeding women to consult healthcare professionals before using Shatavari. Questions about milk supply are ones lactation consultants and clinicians deal with every day.

How Shatavari Compares With Other Herbal Galactagogues

Shatavari is one of several plants with a milk-promoting reputation. This site covers fenugreek, fennel and blessed thistle separately. The 2012 review grouped fenugreek, asparagus and milk thistle together as herbs with anecdotal support but inadequate data at that time.

Since then, Shatavari has gained something several of these herbs still lack: a recent randomised, double-blind, placebo-controlled trial with a clearly stated primary outcome and a positive result. It has not yet gained what would make the claim robust: a second, independent trial, longer follow-up, and a study in mothers with genuinely low supply.

What Is Still Not Known

• Whether the effect seen at 72 hours lasts, or changes how long women breastfeed.
• Whether it helps mothers with established low supply, as opposed to unselected mothers in the first days.
• Whether the effect works through prolactin, and if so how.
• Which constituent, if any single one, is responsible.
• Whether different extracts and powders behave alike.
• Long-term safety for mother and infant.

A 2024 review of Ayurvedic herbs in women's reproductive health, which included Shatavari, set out to assess "the methodological rigor of existing studies" and acknowledged "the need for further rigorous research and clinical trials." For lactation, that remains the honest summary.
