Other species of peppers, such as P. Iongum, P. cubeba, and P. guineense, produce peppercorns that are used locally for medicinal purposes, or are made into oleoresins, essential oils, or used as an adulterant of black pepper. Berries of pepper trees from the genus Schinus, family Euphorbiaceae, are not true peppers, but are often combined with true peppercorns for their color, rather than their flavor. S. terebinthifolius is the source of pink peppercorns, but must be used sparingly, because they are toxic if eaten in large quantity.
