An Excerpt from the "Making More Milk: A Nursing Mother's Guide to Milk Supply" by Diana West and Lisa Marasco (publication TBA)
Shatavari, or shatawari, comes from the Ayurvedic tradition of healing. Also known as “hundred husbands” for its beneficial effects in women and reproductive function, shatavari is also very popular as a galactogogue in India and China. Shatavari is considered to rejuvenate female function and is used for infertility. One older study found that shatavari “increased the weight of mammary tissue and milk yield in estrogen-primed rats” while inhibiting involution of glandular tissue and maintaining milk secretion,(1) while another found shatavari to increase milk production in buffaloes.(2) In contrast, a more recent human study reached the conclusion that it had no real effect (baseline prolactin levels in both groups declined at the same postpartum rate) even though the mothers using shatavari had a greater decrease in necessary supplemental milk for their babies at the end of the study than did mothers who took a placebo.
Shatavari has also been used for gastric problems and has even been tested against metoclopramide, where it was found to have a comparable ability to accelerate gastric emptying.(3) Another study using an alcoholic extract of shatavari found that it caused an increase in serum prolactin levels.(4) The mechanism for increasing milk production seems to parallel that of metoclopramide. Shatavari can be purchased in capsule form and is also an ingredient in Lactare, a galactogogue product, which also contains licorice, fenugreek, ashwaganda and other ingredients.
One rather perplexing fact is that shatavari is also reputed to be able to block oxytocin receptors in the uterus,(5) which may be why it is considered useful for preventing miscarriage or premature labor in the Ayurvedic tradition. This raises the question as to whether it could possibly interfere with oxytocin and milk ejection during lactation. Nevertheless, multiple anecdotal reports have attributed milk production increase to shatavari.
