Lycopus americanus (Common Water Horehound)

Common Water Horehound is in the mint family, but it does not have aromatic leaves. The large, rounded teeth on the leaves distinguish this plant from other species in the genus Lycopus. Small, white flowers bloom in the leaf axils from July to September. Found in damp meadows or in wet places by ponds or streams. Waterfowl eat the small fruits.

Additional Information:
The whole plant is used in various homeopathic remedies including as an astringent, hypoglycaemic, mild narcotic and mild sedative.
