The longan (Dimocarpus longan) is a tropical fruit tree species native to Southern China, India, and other regions of Southeast Asia. The name "longan" is derived from the Cantonese word 龙眼 (lùng yǎn), which translates to "dragon eye," a reference to the fruit's appearance. In Hebrew, the fruit is known as לונגאן (longan), and in Spanish, it is called longan or ojo de dragón (dragon eye). The fruit is similar to the lychee but is smaller, with a thin, tough, brownish-yellow rind that encases translucent, juicy flesh and a single large seed. Longan trees thrive in warm, humid climates and are cultivated for their sweet, aromatic fruit, which is commonly consumed fresh or used in various culinary applications, including desserts, beverages, and preserves. The fruit is also valued in traditional Chinese medicine for its perceived health benefits, including improving digestion and boosting the immune system.
