Viper's Bugloss (Echium vulyare), the flowering tops of which were recommended for the bite of the viper ; 

 Gromwell (Lithospermum officinale), commonly termed Pearlwort, on account of its hard and pearl-grey 

 nucules, which were supposed to be of use in dissolving bladder-stones ; and Heliotropium europeeum, of which 

 the bitter and salt leaves were applied to ujcers and warts. Tournefortia umbellata is still used in Mexico 

 as a febrifuge. In tropical America and in India certain species of Tiaridium are used in herpetic affec- 

 tions. Some Ehretiece have an edible fruit. Finally, the roots of several species of Anchusa, Onosma, 

 Lithospermum, Amelia, contain a red colouring matter, soluble in alcohol and fatty bodies, which is em- 

 ployed to colour certain unguents and other external applications.
