Vurâna was a pinkish paste refined from the leaves or flowers of vuranar, a wildflower of the composite family closely related to uranil, native to tropical tallgrass plains or savannas. Its leaves and flowers resembled those of the chrysanthemum. Vurâna was prepared by boiling vuranar in salt water containing finely ground flour, which collected on the container's walls as vurâna paste.If eaten raw, vuranar was a generic respiratory poison.
