What Is Longan Good For?
In Asian countries like China and Vietnam, longan (Euphoria Longan) is often called “Dragon’s Eye” because of the white eye-shaped mark on the pit – giving it the appearance of an actual eyeball. And just like the mythical creature it’s been named for, longan fruit has been dubbed “magical” because of its wholesome benefits – Don’t underestimate it because of its small size. Here’s everything you should know about the humble longan berry.
What Is Longan?
Longan refers to an evergreen tree from the soapberry family, and is indigenous to China and India (although it is now grown all over Southeast Asia1). This medium-sized tree can grow up to 20 to 23 feet in height, with a cork-like bark and roundish crown. Its leaves are shiny dark green, with a leathery texture and pointed tips.2
The star of this plant, however, is the fruit. Small and round, longan berries have a fragile, pale brown skin (called a pericarp3), a sensitive, whitish, almost transparent flesh and a small brown or black seed in the center. The berries are a little bit bigger than olives.4
Some people think that there’s not much distinction between longan versus lychee, but you should know that these are two different plant species. They’re closely related, though, and longan is often called lychee’s “little brother.”5 It’s also related to rambutan (minus the spiky red skin).
In addition, longan berries are said to be “more gratifying” than the lychee. Its flesh is juicy and deliciously sweet, with a musky flavor almost similar to that of grapes.6
Longan trees grow best in areas with tropical weather, where the autumns are dry and there’s no frost during winter. The trees are cultivated as a food source, but in cold areas, they’re usually grown only as an ornamental plant because they cannot produce fruit in low temperatures.7
The Many Health Benefits of Longan
This fruit may be small, but it surely packs a wallop when it comes to nutritional benefits. You can get vitamins B1, B2 and B3 from longan, and it’s also a good source of free radical-scavenging vitamin C. When it comes to minerals, iron, copper, potassium and magnesium are some standout mentions.
You can also get protein and dietary fiber from longan.8 Plus, it has phenolic acids that can provide you with antioxidant, antiviral, antifungal and antibacterial effects.9 Because of this impressive variety of nutrients, longan berries have been linked to numerous health benefits, some of which include:
- Helps bolster your immunity against colds and flu – The vitamin C in longan berries improves your defense mechanism, and is also essential to iron absorption and improving skin health.10
- Promotes optimal blood circulation – This is mainly due to its high iron content, which is said to be 20 times higher than grapes and 15 times higher than spinach.11 Consuming longan may also help prevent anemia.
- Helps maintain cardiovascular health – By rejuvenating blood circulation, longan berries can effectively stimulate the spleen and help improve heart conditions, reducing the risk of cardiac arrest and stroke. It can also soothe the nervous system.12
