Bugleweed is a plant. People use the parts that grow above the ground for medicine.
Bugleweed is used to lower high levels of thyroid hormones (hyperthyroidism). It is also used to treat premenstrual syndrome; breast pain; nervousness; trouble sleeping (insomnia); and bleeding, especially nosebleeds and heavy bleeding during menstruation.
How it works
Bugleweed might reduce the body's production of thyroid hormone. Bugleweed also seems to reduce the release of the hormone prolactin, which might help relieve breast pain.
