Among above herbs, Valerian, Vervain are introduced in TCM herbalism.
Brief Introduction: Valerian is the dried rhizomes and roots of Valeriana officinalis, a tall perennial that grows in temperate regions of North America, Europe, and Asia. Clusters of tiny white or reddish flowers bloom in summer. The herb emits an unpleasant odor as it dries. There are about 250 Valeriana species, but V.officinalis is the species most frequently cultivated for medicinal use.
Brief Introduction: Verbena officinalis and Verbena hastata represent only two of hundreds of species in the family Verbenaceae. These common perennials grow wild in temperate regions around the world. Slender flowering spikes emerge off thin, stiff stems; the lilac or blue color of the small flowers accounts for the common American name, "blue vervain". The flowers, the roots, and the oblong leaves are used medicinally.
