What is it used for?
Traditional uses of bugleweed include treatment of nosebleeds, heavy menstrual bleeding, and coughs. It has also been used as a sedative, astringent, and mild narcotic, and for tuberculosis characterized by bleeding from the lungs. More current uses are primarily for mild hyperthyroid conditions and for premenstrual syndrome, including breast pain (mastodynia).
Bugleweed is used to treat mild hyperthyroidism, premenstrual syndrome, and breast pain; however, there are few clinical studies to support these uses.
What is the recommended dosage?
Clinical trials are lacking regarding dosages for specific clinical applications. A daily dosage of 2 Thyreo-loges N tablets (Lycopi europaei herba 40 mg/day) taken in divided doses was used for 3 months in an open-label clinical study for mild hyperthyroidis.
