Kaffir Lime (Citrus hystrix)

Citrus hystrix, commonly known as kaffir lime, is a tropical citrus tree in the Rutaceae family. Native to Southeast Asia, it is cultivated for its aromatic leaves and bumpy green fruits, both of which are widely used in culinary applications, especially in Southeast Asian cuisine. Traditionally, various parts of the plant—including leaves, zest, and fruit—have been used in folk medicine for their digestive, antimicrobial, and anti-inflammatory properties. With its culinary, medicinal, and aromatic significance, Citrus hystrix remains an important species in tropical home gardens and regional food traditions.
