Goat’s Rue, scientifically known as Galega officinalis, is a traditional herb. This herbaceous plant belongs to the legume family, Fabaceae, and is native to parts of northern Africa, western Asia, and Europe. It typically grows to about three feet tall and features slender, bright green leaves with blue or white pea-like flowers that bloom during summer months. Historically, Galega officinalis has been cultivated for various purposes, including as forage, an ornamental plant, green manure, and in traditional medicine.
Key Benefits for Lactation Support
Goat’s Rue is widely recognized as a galactagogue, a substance that promotes increased milk production. Its name Galega directly references its ability to encourage milk flow. Research indicates that Galega officinalis contains compounds such as galegine, flavonoids, and alkaloids that stimulate mammary glands and enhance the development of mammary tissue. This mechanism is particularly beneficial for mothers who may have insufficient glandular tissue or are experiencing low milk supply.
The active compounds in Goat’s Rue also contribute to increased prolactin levels, a hormone crucial for initiating and maintaining milk supply. Clinical trials show that mothers using Goat’s Rue experienced increased milk supply within days, sometimes outperforming other galactagogues like fenugreek. Its effectiveness is noted particularly for those with hormonal conditions like polycystic ovary syndrome (PCOS), which can interfere with milk production. This makes it a popular plant-based supplement for nursing mothers seeking to naturally boost their milk supply.
Other Potential Health Applications
Beyond its well-known lactation support, Goat’s Rue has other traditional and emerging health applications, notably in blood sugar regulation. Historically, this plant was used to manage blood sugar levels, and its active compounds, particularly galegine and guanidine derivatives, were instrumental in the development of metformin, a widely used medication for type 2 diabetes. These compounds are believed to enhance insulin sensitivity and help regulate glucose metabolism, reducing blood sugar levels. While it can help maintain healthy glucose levels, it should not replace conventional diabetes treatment without professional guidance.
The herb also possesses antioxidant properties, attributed to compounds like flavonoids such as quercetin, kaempferol, and rutin. These antioxidants may help reduce oxidative stress and inflammation in the body. Traditional medicine mentions the use of Goat’s Rue for digestive issues, including constipation, due to its diuretic and tonic properties. It is also believed to stimulate pancreatic and liver functions, contributing to overall digestive health. While these applications have historical roots, the scientific backing for them is less robust compared to its lactation benefits, and they remain subjects of ongoing research.
How to Use Goat’s Rue
Goat’s Rue is available in various forms, including capsules, tinctures, and teas. For tinctures, a common suggestion involves taking 1 to 2 mL, two to three times daily, often mixed with water or juice. If using dried herb for tea, approximately 1 teaspoon steeped in 1 cup of boiling water, taken twice daily, is a common recommendation. For capsules, dosages vary based on the product’s concentration, but some suggest taking one capsule four to six times throughout the day.
Consulting a healthcare professional or a qualified herbalist is always recommended before starting any new supplement regimen. They can provide personalized advice and ensure its appropriate use.
Safety and Precautions
While generally considered safe when used appropriately, Goat’s Rue can have potential side effects and contraindications. Some individuals may experience mild digestive upset.
A significant consideration is its ability to lower blood sugar levels, which necessitates caution for individuals with diabetes, especially if they are already on blood sugar-lowering medications, as it could lead to hypoglycemia. Monitoring blood sugar closely in such cases is important.
Goat’s Rue might also slow blood clotting, increasing the theoretical risk of bruising and bleeding. Therefore, individuals with bleeding disorders or those taking anticoagulant or antiplatelet medications should exercise caution. It is generally advised to stop using Goat’s Rue at least two weeks before any scheduled surgery due to its potential impact on blood sugar and clotting. While often used for lactation, there is insufficient reliable information regarding its safety during pregnancy, and avoiding its use during this period is typically recommended.
