The fruit grows in clusters on evergreen trees, typically reaching heights of 30 to 40 feet. Its name, "longan," is derived from the Cantonese word for "dragon eye," a fitting description given the fruit's appearance when peeled, revealing a dark seed within its translucent flesh. Longan fruits are small, usually about the size of a grape, with a thin, light brown shell that is easily peeled away. The flesh is juicy and sweet, often described as having a slightly floral or honey-like taste. In traditional Chinese medicine, longan is believed to have various health benefits, including promoting relaxation, improving sleep quality, and boosting energy levels. Rich in vitamins, minerals, and antioxidants, longan is not only delicious but also nutritious. Consumed fresh, dried, or incorporated into various dishes and beverages, longan is a versatile fruit enjoyed worldwide. Its unique flavor profile and health properties make it a popular choice for both culinary and medicinal purposes.
