Herbs That Promote Breast Growth

In antiquity, breast-enhancing herbs were used to increase milk secretion in breastfeeding mothers. As of 2010, herbal galactagogues (substances that increase milk production) are still considered safe, effective treatments for low milk supply, according to renowned lactation expert Kelly Bonyata on her website KellyMom. However, the use of herbs to cosmetically enhance breast tissue remains controversial. Experts, such as Mayo Clinic physician Sandhya Pruthi, warn that no large-scale studies have evaluated the safety or efficacy of breast-enhancing herbs. Women who are coping with medical conditions should consult a licensed practitioner before taking any herbal supplement.

Licorice

According to MedlinePlus, licorice supplements can spike levels of estrogen and prolactin within a woman's bloodstream. These two hormones are both associated with lactation and increased breast size. Licorice's estrogenic effects also make the herb a possible (but unproven) treatment for menopausal symptoms and hormonal imbalances.

Fennel

A relative of dill weed, fennel contains three volatile oils identical to those found in licorice. The December 1980 "Journal of Ethnopharmacology" reported that the compounds anethole, dianethole and photoanethole appear to influence human estrogen levels. Bonyata reports that fennel is a marginally effective galatagogue and breast enhancer.

Blessed Thistle

MedlinePlus acknowledges blessed thistle's traditional use as a breast milk enhancer, but, as of 2010, no studies have evaluated its efficacy. MedlinePlus notes that the herb is generally safe when used as directed for short periods of time.

Fenugreek

This fragrant Ayurvedic herb is used to season curries, soups and other South-Asian dishes. Unlike most other breast-enhancing herbs, fenugreek contains no estrogen or estrogen-like plant compounds. Instead, according to Bonyata, it works by elevating levels of the lactation-related hormone oxytocin. "The Ultimate Breastfeeding Book of Answers" also suggests that fenugreek affects dopamine levels; this would make it pharmacologically similar to the prescription galactagogue domperidone.
