Overview
[ Back to top ]
Tephrosia is a genus of flowering plants in the pea family, Fabaceae. The generic name is derived from the Greek word tef??? (tephros), meaning "ash-colored," referring to the greyish tint given to the leaves by their dense trichomes.2]
Uses
[ Back to top ]
Many species in the genus are poisonous, particularly to fish, for their high concentration of rotenone. Tephrosia species have historically been used by indigenous cultures as fish toxins.[3] In the last century, several Tephrosia species have been studied in connection with the use of rotenone as an insecticide and pesticide.
