See text Solanum mammosum, commonly known as nipplefruit,[1] fox head,[2] cow's udder, or apple of Sodom, is an inedible Pan-American tropical fruit.

It is an annual in the family Solanaceae, and part of the genus Solanum, making the plant a relative of the eggplant, tomato, and potato.

Folkloric uses of the plant range from treating asthma with a root decoction, to curing athlete's foot by rubbing leaf juices on the skin.

The juice of the fruit can be used as a detergent in place of a washing powder, making it similar to the soap nut.

In the Philippines, not only is the fruit eaten, but the leaves are also prepared as a tea considered to be anodyne,[citation needed] a mild narcotic.
