Galega officinalis, commonly known as goat's rue, French lilac, Italian fitch, or professor-weed, is a bitter and strong-smelling herb that grows in the Middle East, southern Europe, and western Asia.
Although now considered a weed, goat's rue was introduced into the United States in 1891 as forage for livestock.
Goat's rue has been traditionally used to increase breast milk production and treat diabetes. Goat's rue may also help control blood sugar and promote weight loss.
Although not well studied in humans, goat's rue may interact with medicines taken to reduce blood sugar or reduce the risk of bleeding.
Galegine, a Galega extract, led to the development of the only approved biguanide antidiabetic drug, metformin.
