Goat’s Rue is noted today for its ability to increase Mother’s milk, dramatically. The traditional use of Goats rue was to treat diabetes and has been a staple since the middle ages. Goats rue contains an alkaloid, galegine, that was found in clinical trials to decrease blood sugar and insulin resistance. This lead to the development of metformin, which is currently used in the medical treatment of diabetes. Studes in mice also point to a weight-reducing action for goat’s rue that appears to involve a loss of body fat. The medical community now favors the prescription drug for diabetes so the plant is used today for increasing lactation.
