The Voynich Botanical Plants

Folio 21v. Burning bush, False Dittany (Dictamnus albus), is a native of southern Europe. During the summer, the whole plant is covered with a gluey volatile substance, which may cause the plant, in very hot weather, to ignite spontaneously. Hence the name burning bush. The plant is inedible and the leaves taste very bitter. The root was once used as a remedy for epilepsy and diseases of the head, to help resist poison and for cases of hysteria. (1) (C)
