Medicinal Actions & Uses

Bugleweed has sedative properties and today the herb is principally prescribed to treat an overactive thyroid gland and the racing heartbeat that often accompanies this condition. Bugleweed is also considered an aromatic and tonic astringent that reduces the production of mucus.


Studies indicate that bugleweed and, to some degree, gipsywort (see Related Species, below) reduce the activity of the thyroid gland.

Related Species
