Comment: The fruits contain a natural detergent and have been used as a substitute for soap. The practice is not recommended, since it causes a skin rash in some people. The fruits are poisonous and should not be eaten. Sapindus is from a Latin phrase meaning "soap of the Indes"; saponaria refers to a soaplike substance called saponin found in the fruits; drummondii honors Thomas Drummond, who collected plants in Texas for Joseph Hooker.
