What is Blue Vervain?

Blue Vervain is a tall perennial with narrow lance-shaped leaves and small purple-blue flower spikes that rise above the plant in summer. The species is native to wet areas of central and eastern North America. Blue Vervain figures in several Native American herbal traditions and was widely used in 19th-century Eclectic Western herbalism as a nervine, bitter tonic, and women's wellness herb.

How to Use Blue Vervain

For tea: steep 1 teaspoon of dried herb per 8 oz cup in hot water for 10 minutes, then strain. The flavor is intensely bitter; combining with sweeter herbs or honey improves palatability. Often used in nervine blends with skullcap, passionflower, or oat straw.
