Veriloid, a New Hypotensive Extract of Veratrum Viride.

Abstract
"Veriloid," a stable, reproducible and highly potent extract of V. viride. is described. Methods of biological control of potency have been developed. In normal dogs the extract was hypotensive, bradycardic and emetic. Pharmacologic results suggest that the hypotensive action of the extract deserves trial in the treatment of human hypertension.
