Kaffir Lime Leaf

The rind of the kaffir lime is commonly used in Lao and Thai curry paste, adding an aromatic, astringent flavor. Its hourglass-shaped leaves (comprising the leaf blade plus a flattened, leaf-like leaf-stalk or petiole) are also widely used in Thai and Lao cuisine (for dishes such as tom yum), and Cambodian cuisine (for the base paste known as "Krueng"). The word Kaffir have may come from German Kaefer, meaning bug. The leaves of the Kaffir Lime do bear a slight resemblance to an insect, especially the leaf insects native to Southeast Asia, with which they may have co-evolved.

Kaffir lime trees (Citrus hystrix) have been cultivated in Southeast Asia for centuries. The tree has dark green, glossy leaves with a bumpy texture, and its fruit is small and highly acidic.

Additionally, the leaves contain a high concentration of antioxidants, which help to protect against oxidative damage and inflammation. Some studies have also suggested that kaffir lime leaves may help to lower cholesterol levels and improve digestive function.
