Longan is related to the well-known lychee and the slightly lesser-known rambutan. You can easily peel the fruits and eat them on the go. Longan is also often canned. In China, the seed coat is used fresh or dried in tea or water. The seeds, which are rich in saponin, are used as shampoo. The wood is used for carving and making furniture. The appearance of this fruit is somewhat reminiscent of a dragon’s eye, which is where the Chinese name “longan” comes from.
