Any of several creeping plants of the mint family, especially Ajuga, with blue or purple flowers, used in gardens and traditional medicine.
From 'bugle' (the plant, from Old French, related to Latin 'buculus') plus 'weed,' combining two plant names. The bugle plant itself was named for its horn-like flower shape.
Bugleweed is traditionally used to suppress appetite and was sold as a diet aid in the 1900s, though modern science hasn't confirmed these effects—it's a great example of how old plant remedies get rediscovered.
