Traditional Benefits
Traditionally used across Europe and the Middle East, Goat’s Rue has been revered for its ability to increase milk supply in nursing mothers and support metabolic health. In folk medicine, it was administered to stimulate the production of breast milk, reduce fevers, eliminate intestinal worms, and support urinary health. The plant’s name—“Galega”—derives from Greek roots meaning “milk” and “to bring on,” highlighting its longstanding reputation as a galactagogue.

A Natural Allergy Ally
Though not primarily used for allergies, its anti-inflammatory and immune-balancing qualities may offer indirect support to inflamed mucous membranes during seasonal flare-ups.

A Herb for Seasonal Support
Its gentle diuretic and metabolic actions can support spring detox protocols. Additionally, its immune-enhancing and antimicrobial activity can offer support during times of immune stress.

How It Works
Goat’s Rue contains galegine, a guanidine compound that lowers blood glucose levels by improving insulin sensitivity. This compound is considered the precursor to metformin, a common pharmaceutical drug used in type 2 diabetes. The herb also contains flavonoids, tannins, and alkaloids that support circulation, lactation, and gentle cleansing of the urinary tract. Its bitters enhance digestion, while its cooling energetics calm inflammatory conditions.

Best Ways to Use It
Tinctures/Extracts: 2–4 mL of a 1:5 tincture, 2–3x daily for blood sugar and lactation support.
Herbal Teas: Steep 1–2 teaspoons in boiling water for 10–15 minutes; drink 2–3x per day.
Capsules: Typically found in lactation blends; follow package instructions.
Topical Poultices: Traditionally used on inflamed tissues and minor infections.

Fun Fact
Goat’s Rue was once grown as fodder for livestock because it increased milk yield—not just in humans, but in goats and cows too. Its historical name “French lilac” reflects both its country of popular origin and its resemblance to the lilac plant.

A Herb for Modern Use
Goat’s Rue is now a cornerstone herb in many natural lactation formulas, often blended with fenugreek, fennel, and blessed thistle. Its legacy lives on in modern diabetes care: galegine’s role as a forerunner to metformin shows how traditional herbs have shaped contemporary pharmaceuticals. Herbalists also use it in metabolic and hormonal support protocols, particularly for individuals with insulin resistance, PCOS, or metabolic syndrome.

Safety Considerations
Use with caution in pregnancy due to uterine-stimulating effects. Best reserved for postpartum or therapeutic use under supervision. May lower blood sugar—diabetics should monitor levels closely. Not recommended for individuals with hypoglycemia or those on blood sugar–lowering medications without guidance.
