A tropical climbing plant whose roots contain rotenone, a natural insecticide used to kill pests like fleas and insects.
From the genus name 'Derris,' derived possibly from a Malayan or Southeast Asian word. The plant was scientifically catalogued in the 18th century and its insecticidal properties were exploited commercially.
Derris is a natural pesticide that was huge before synthetic chemicals took over—it's still used in organic farming today because it breaks down safely and kills insects without harming mammals!
