The number of medicinal gesneriads was probably even larger in decades and centuries past, when the Amer-Indian people prospered and the rain forests were still intact. It is remarkable that 50% (61 species of the bioactive gesneriads listed are cited as remedies for the bite of deadly poisoous snakes, such as bushmaster, fer-de-lance and coral snake.
