SOAPBERRY

Soapberry (Sapindus saponaria) is a tropical American tree of the natural order Sapindaceae. The soapberry has alternate leaves and small greenish-white flowers. The fruit is fleshy and contains hard, black, round seeds that have been used as beads and buttons. The outer covering of the seeds when soaked in water produce a lather, and have been used as a natural soap. The root may also be used as a soap but is less effective.
