Piperaceae is an economically important plant family. Members of this family grow in tropical forests from South Asia to Tropical America, including those of Africa and Australia. Several Piper spp. from India, southeast Asia and Africa are of economic importance since they are used as spices and traditional medicines. Many plant families have a global distribution, but a few have the rich ethnobotanical and ethno pharmaceutical history of Piperaceae. The pepper family Piperaceae in the order Piperales is commercially important because of Piper nigrum L. the source of black and white pepper. Betel leaf is another economically important product obtained from piper betle. The family comprises about 5 genera of which 2-Piper (about 2,000 species) and Peperomia (about 1,600 species)- are the most important. The plants grow as herbs vines shrubs, and trees and are widely distributed throughout the tropics and subtropics. The Piper belte L. P longum L. P. chaba Hunter are the some of the other important members of Piperacea family. The book contains useful information on various aspects of the family starting from taxonomy, botany cultivation to the medicine uses.
