Beeo Keeo longans on sale in a market.

Longans are also a good source of copper and manganese, which help to maintain healthy hair and skin. Copper is also useful for helping the body to absorb iron, making the longan a good fruit for people who are anemic. Copper also helps to maintain and repair the connective tissues of the heart and arteries.

There are two main varieties of longan sold in the markets. See Chompoo or "pink colored" is the most highly prized. As its name implies, the flesh has a slightly pinkish color to it. The other type, Beeo Keeo, looks similar on the outside, but the flesh is more greenish.

The bigger the Long Tong, the more you pay!

Another fruit looks very similar to the longan, and in Thai it’s known as long tong. Long tongs are larger than longans and generally much sweeter. For this reason, the fruit is usually much more expensive than the longan.
