Overview

Goat's rue is a perennial plant that is native to the Middle East but is now found in many parts of Europe and Asia. It has been used for centuries in traditional medicine for a variety of purposes, but it is best known for its ability to increase milk supply in breastfeeding mothers. The leaves and flowering tops of the plant are used to make herbal supplements. Goat's rue contains compounds called galegine and guanidine, which are believed to be responsible for its galactagogue effects. These compounds are thought to stimulate the development of mammary tissue and increase the production of prolactin, a hormone that is essential for milk production. In addition to its use as a galactagogue, goat's rue has also been traditionally used to lower blood sugar levels. In fact, the diabetes drug metformin was originally derived from goat's rue. While goat's rue is generally considered safe for short-term use, it can cause side effects such as headache and digestive upset. It can also interact with certain medications, so it is important to talk to a doctor before taking it.
