Pyrethrum extract is a natural insecticide made from the flowers of certain species of the chrysanthemum plant. It is a mixture of several different compounds called pyrethrins and cinerins. Pyrethrum is extracted with solvents but is still widely used in insect sprays where it is usually combined with another chemical called piperonyl butoxide.
