Rambutan: Health Benefits, Nutritional Value, and Uses

Rambutan (Nephelium lappaceum) is a tropical fruit often called “Hairy Lychee” due to its spiky appearance. Native to Southeast Asia, this exotic fruit has been cultivated for centuries for its unique taste and numerous health benefits.

Rambutan trees are evergreen and can reach heights of 40 to 65 feet (12-20 meters). They have dark green, glossy leaves and produce brightly colored fruits covered in hair-like spikes when ripe. Each rambutan fruit is about the size of a small golf ball and contains white, juicy, and sweet-sour-flavored flesh.
