This species of skullcap is native to moist meadows over a wide area in North America.  It is the most popular and common skullcap among herbalists in the U.S.

The tea or tincture of the flowering top is a very effective sedative nervine that not only helps calm the nerves and reduce anxiety, but also helps to relax tight muscles.  Further, this is a nutritious plant with lots of minerals and antioxidants that help protect tissues from oxidative damage.

This hardy perennial herb in the mint family bears purple-blue flowers on stalks about two feet tall.  Skullcap likes moist soil and sunny locations in the garden.
