Lychee is a tropical fruit that is native to South China, Malaysia, and northern Vietnam, but is now grown commercially in many regions including India, Vietnam, Indonesia, Australia, and the United States. The fruit is round or oblong in shape, with a bumpy, red peel and white, sweet interior similar to a grape. The fruit is usually eaten fresh but can also be used in tropical fruit salads, blended into cocktails, juices, smoothies, and desserts. Lychee is also known as "alligator strawberry" for its red, bumpy skin. The fruit is composed of three layers: the reddish husk, white flesh, and brown seed. The exterior of the fruit is a pink-red, rough-textured soft shell, and the fruit varies in shape from round to ovoid to heart-shaped, up to 5 cm long and 4 cm wide, weighing approximately 20 g. The fruit is primarily composed of water and carbs, most of which are sugars, and is a good source of vitamin C, copper, and potassium. Lychee seeds contain methylene cyclopropyl glycine which has caused hypoglycemia associated with outbreaks of encephalopathy in undernourished Indian and Vietnamese children who consumed lychee fruit.
