Shatavari
Asparagus racemosus
An Ayurvedic 'queen of herbs' from the root of a wild asparagus, traditionally used for women's reproductive health, lactation, and digestion; human evidence is limited to small trials on breast milk supply and menopausal symptoms.

What is Shatavari?
Shatavari is the tuberous root of Asparagus racemosus, a thorny climbing plant found throughout India, Nepal, and Sri Lanka. In Ayurveda it is classed as a rasayana (rejuvenative tonic) and is the leading herb for women's health, used across the life span for menstrual regulation, fertility, pregnancy support, lactation, and menopause. The name is usually translated as 'she who possesses a hundred husbands' or 'a hundred roots,' referring to its reputation for fertility and vitality and to the plant's cluster of finger-like tubers. It is also used in Ayurveda as a cooling, soothing herb for gastritis, ulcers, dry cough, and as a general adaptogen. It is now widely available in the West as powders, capsules, and lactation teas.
Known Health Benefits
How It Works
The steroidal saponins (shatavarins) are structurally similar to plant sterols and are proposed to have mild estrogenic or estrogen-modulating effects, which may explain traditional uses for menopause and cycle regulation; isoflavones contribute weak phytoestrogen activity. In lactation studies, shatavari raised prolactin levels, suggesting an action on the pituitary or hypothalamus, though the responsible constituents are unknown. The mucilage and oligosaccharides form a protective coating on gastric mucosa and increase mucus secretion, which underlies its traditional use for ulcers and reflux; animal studies show it reduces gastric acid and protects against stress-induced ulcers. Shatavari extracts have antioxidant activity, modulate immune cells, and in rodent models reduce stress hormone elevations, supporting its classification as an adaptogen.
What Research Says
Human research on shatavari is sparse and mostly from India. The best-known lactation trial, a 2011 RCT of 60 breastfeeding mothers, found that 60 mg/kg/day of shatavari root powder for 30 days increased prolactin levels by about 33% versus placebo and that mothers reported greater infant weight gain and satisfaction, though milk volume was not directly measured. An earlier 2004 Indian study found no difference from placebo, highlighting inconsistency. A 2018 pilot RCT of 70 Indian menopausal women reported that a shatavari extract reduced hot flashes, night sweats, and vaginal dryness over 8 weeks, but it was small and single-center. A 2021 trial in Nepal found a shatavari-based formulation improved muscle strength in older women. Laboratory and animal studies on gastric protection, immune modulation, and antioxidant effects are numerous and consistent, but no human trials exist for digestive conditions. Shatavari's long history of use suggests a good safety profile, but its reputation rests mostly on tradition rather than rigorous clinical evidence.
Active Compounds
Steroidal saponins (shatavarins I–IV), racemofuran, asparagamine A, isoflavones, mucilage, oligosaccharides, flavonoids (rutin, quercetin)
Forms & Bioavailability
Shatavari saponins are absorbed to a limited degree and partly metabolized by gut bacteria; no human pharmacokinetic studies exist. Traditional preparation with milk and ghee is thought to improve the absorption of the fat-soluble sterols and saponins, and many practitioners recommend taking the powder with a fat-containing food or drink. Mucilage acts locally in the stomach without absorption. Effects on lactation appeared within 2–4 weeks in trials, while menopausal and adaptogenic benefits are assessed over 8–12 weeks.
Dosage Guidance
| Use Case | Dosage |
|---|---|
| Lactation support | 60 mg/kg/day root powder (about 3–4 g for a 60 kg woman) |
| Menopausal symptoms | 500 mg extract 2x daily |
| Digestive soothing / gastritis | 3–6 g root powder daily in warm water or milk |
| General tonic / adaptogen | 500–1000 mg extract or 3 g powder daily |
Always consult a healthcare provider for personalized dosing.
Natural Food Sources
- Fresh tubers are cooked as a vegetable in parts of India (not comparable to supplement doses)
- Garden asparagus (Asparagus officinalis) is a different species with different constituents
Potential Side Effects
Generally well tolerated; possible allergic reactions in people sensitive to asparagus (rash, runny nose, itchy eyes, breathing difficulty); mild diuretic effect; weight gain reported in some trials
Who Should Avoid It
- Allergy to asparagus or related plants
- Estrogen-sensitive conditions (breast, ovarian, or uterine cancer; endometriosis; fibroids) without medical advice
- Kidney disease or use of lithium (diuretic effect may affect fluid and drug levels)
- Edema due to heart or kidney disease (traditional caution; may retain fluid in some people)
Pregnancy & Lactation
Shatavari has been used throughout pregnancy in Ayurvedic practice, and there are no reports of harm, but modern safety studies are lacking; most Western sources advise avoiding it in pregnancy or using it only under practitioner guidance, particularly given its possible hormonal activity. During breastfeeding, it is one of the more studied herbal galactagogues and appears safe for mother and infant in the 30-day trial; it is a reasonable option to try if milk supply is low, alongside frequent feeding and lactation support, with fenugreek as a common alternative.
Known Drug Interactions
May add to the effect of diuretics; may lower blood sugar additively with diabetes drugs; theoretical interaction with lithium (reduced clearance) and with estrogen-based therapies
Evidence Classification
Based on in vitro studies, animal models, pilot trials, or traditional use documentation. Clinical evidence is limited.
Frequently Asked Questions
Does shatavari actually increase breast milk?
The evidence is modest. One 60-woman trial found a significant rise in prolactin and better infant weight gain versus placebo, while an earlier study found no benefit. Neither measured milk volume directly. Shatavari is unlikely to harm and may help, but effective milk removal through frequent feeding or pumping remains the most important factor in supply. Consult a lactation specialist if supply is a concern.
Is shatavari the same as asparagus from the supermarket?
No. Shatavari is Asparagus racemosus, a wild species whose tuberous root is used medicinally. Garden asparagus is Asparagus officinalis, grown for its young shoots. They are related, so people with asparagus allergy should be cautious with shatavari, but the chemistry and uses are quite different.
Can men take shatavari?
Yes. Despite its reputation as a women's herb, Ayurveda uses shatavari for men as a general tonic, for digestive complaints, and for reproductive health. Animal studies suggest it supports sperm production. Its phytoestrogen content is weak and not known to cause feminizing effects at normal doses.
How does shatavari compare to ashwagandha?
Both are Ayurvedic rasayanas, but they have different characters. Ashwagandha is considered warming and is better studied for stress, anxiety, and sleep, with multiple modern RCTs. Shatavari is cooling and moistening, traditionally favored for women's hormonal health and digestion, but has far less clinical research. They are often combined in Ayurvedic formulas.
