Also known as Longan, the Long Yan fruit has been a staple in traditional Chinese medicine and Asian cuisines for centuries. Often overshadowed by its cousin the lychee, Long Yan may be small in size, but it’s packed with flavor, nutrients, and powerful health benefits.
In this blog, we’ll explore everything you need to know about Long Yan fruit—its origins, nutritional value, health benefits, how to eat it, and why this tropical gem is making a comeback in the world of natural wellness.
🌿 What Is Long Yan Fruit?
Long Yan (龙眼), which literally means “dragon eye” in Chinese, is a tropical fruit native to Southern Asia, particularly China, Vietnam, Thailand, and India. It grows on the Dimocarpus longan tree and belongs to the soapberry family—just like lychee and rambutan.
The fruit has:
- A thin, tan shell
- Translucent, juicy white flesh
- A shiny black seed in the center (which gives it the “eye” appearance)
It has a sweet, floral taste that’s slightly musky—less juicy than lychee but often preferred for its richer aroma and medicinal qualities.
🍽️ Nutritional Value of Long Yan Fruit
Longan is low in calories and packed with vital nutrients. A 100g serving of fresh Longan contains:
- Calories: ~60
- Carbohydrates: 15g
- Sugars: 13g
- Vitamin C: ~84 mg (140% of the daily value!)
- Iron: Small amounts
- Potassium: ~266 mg
- Antioxidants: Polyphenols, gallic acid, and corilagin
Dried Longan (Long Yan Rou) is even more concentrated in nutrients and is commonly used in herbal teas and traditional medicine.
