Goat's Rue

By H. Zell/ Wikimedia

Goat's rue (Galega officinalis) is a plant native to Europe and the Middle East. It has been used in herbal medicine to treat tuberculosis, lower blood sugar and improve the milk supply of nursing mothers. In Europe, the dried leaves were fed to cows and goats to increase milk production. It was brought over to the United States in the late 1800's to provide a food source for livestock. Unfortunately, the plant was not a successful crop due to it's bitter taste and toxicity. It turned out to be harmful and even lethal to some of the animals. Today, goat's rue is considered a noxious weed in the United States.

Benefits and Uses of Goat's Rue

  • It is believed to help nursing mothers build up breast tissue and make more breast milk.

  • Some studies show that goat's rue may help lower blood sugar levels in diabetic patients.

  • It is believed to be useful in cancer research. Studies are now being carried out.

  • It has been used as a diuretic.

  • Goat's rue has been shown to have anti-bacterial properties.

Goat's Rue and Breastfeeding

Popular in European countries, goat's rue is considered a galactagogue often recommended to nursing mothers to help increase the supply of breast milk. It is also used to induce the growth of breast tissue, so it may be helpful for women who wish to breastfeed after breast surgery and those who plan to breastfeed an adopted child.

Goat's rue belongs to the same plant family as fenugreek. Some women report that it works just as well or even better than fenugreek, however, it does not appear to work for everyone.

Capsules: (Compare Prices) A typical dose would be 1 capsule 3 or 4 times a day. Purchase your capsules from a reputable company and follow the dosing directions given to you by your doctor or lactation consultant.


Goat's rue can also be found as an ingredient in some commercially available teas and capsules made specifically for breastfeeding mothers.
