Pepper vine, scientifically known as Piper nigrum, is a tropical climbing plant native to South India. Its berries, which ripen from green to red, are harvested and dried to produce black, white, and green peppercorns. These peppercorns are a cornerstone of global cuisine, renowned for their pungent flavour and aroma. The vine thrives in hot, humid climates and is a significant agricultural product with both culinary and medicinal applications.
