Product Description
Lychee is a sweet and tasty strawberry-red fruit that is a symbol of love and romance in China. As the University of Purdue horticulture website explains, lychee grow in clusters on trees and usually have a round or oval shape. Lychee fruit is roughly one 1 inch long and 1 inch wide. To get at the fruit, you peel off a leather-like skin. The fruit surrounds a rather large seed in the middle. A few days after the fruit ripens, it turns dark and dehydrates, resembling a raisin.
The firmness of the shell of the dried fruit has led some people to label lychee fruit as "litchi nuts." However, as the Purdue website emphasizes, "it is definitely not a nut and the seed is inedible." Although the seed may be inedible, powdered seeds or tea made from lychee seeds are used for medicinal purposes, although actual health benefits seem to be more anecdotal than clinical.
