This Plant is one of the lirft that fprings up after White 
kastata, L. (blue vervain), is perhaps, notwithstanding the author's disclaimer, 
what he had in view. This is certainly different from the common, once officinal, 
vervain of Europe (V. officinalis, L.), — on the virtues of which, as a wound- 
herb, see Gerard, p. 718; but yet more so from true clown's all-heal (Gerard, p. 
1005), which is Stackys falustris, L. As to other medicinal properties of our 
vervains, compare Cutler, I. c, p. 405, — where they are said to have been used 
by the surgeons of our army in the Revolutionary War, — and Wood and Bache, 
Dispens., p. 1403.
