Trung Khanh chestnuts are like a big toe, when roasting them, the flavour is delicate, sweet and nutty, making people who have tasted it cannot forget the heaven like flavour, even just one bite. The fruit is covered by sharp spines like rambutan, each of them contains three or four dark brown seeds.

In The American Journal Of Clinical Nutrition, it is said that chestnut can reduce LDL (bad cholestrol) for people with high LDL.

Certainly, the chestnut can be used to cure people.At the moment, the brand of Trung Khanh chestnut has been all over the North of Vietnam and even China.
