Longan
Dimocarpus longan · Sapindaceae · also known as Dragon's eye (lóngyǎn), Lungan
The "dragon's eye" — lychee's smaller, tan-shelled cousin with muskier honey flavor and a black seed staring from translucent flesh. Beloved fresh in summer, dried year-round in Chinese kitchens and teas.

Its name means "dragon's eye" — shelled, the dark seed glows through the translucent flesh and stares back.
How to select & store
Picking a ripe one
Choose full, heavy sprays with unbroken tan shells that crack crisply under a thumbnail. Avoid dented or weeping fruit; a sour smell means fermentation has started.
Storing it
Better keeper than lychee — a week-plus refrigerated in a bag. Dried longan (shelled, seeded, raisin-like) keeps a year and is a pantry staple in its own right.
Practical uses
🍽️ Culinary
- Peeled and eaten by the branchful, chilled
- Longan sweet soups (tong sui) with lotus seeds and red dates
- Dried longan in herbal teas, congee, and braised dishes
- Canned longan over shaved ice and in fruit cocktails across Southeast Asia
🌿 Health & traditional
- A named tonic in traditional Chinese medicine (guiyuan) for blood, calm, and sleep — usually as dried fruit in decoctions
- Warming-food classification pairs it with cooling partners in TCM meal logic
🎎 Cultural
- The name means "dragon eye" — shelled fruit with its dark seed showing really does stare back
- Thailand's Lamphun province throws an annual longan festival; northern Vietnam's nhãn lồng of Hưng Yên was royal tribute fruit
Shell a longan and you’ll see the name: translucent flesh with a glossy black seed glowing through — lóngyǎn, the dragon’s eye. It’s the lychee’s workaday cousin: smaller, tan instead of scarlet, less perfumed but sweeter-muskier, cheaper by the kilo, and a better keeper — the soapberry family’s daily driver rather than its show pony.
Two careers: fresh and dried
Fresh longan is a summer street fruit across China, Thailand, and Vietnam. But its second life matters just as much: dried longan — dark, chewy, honeyed — is a named ingredient in the Chinese pantry, dropped into tong sui dessert soups, eight-treasure congee, herbal teas, and TCM tonics for “nourishing the heart and calming the spirit.” Few fruits hold official positions in both the fruit bowl and the medicine cabinet.
Buying and eating
The shell should crack like a thin eggshell; inside, roll the flesh off the seed with your tongue and discard the pit. If choosing between longan and lychee at the same stall, the honest answer is both — with rambutan for the full soapberry trilogy.
