Are Lychees Good For Health?Lichi (lychee) is a small, tropical stone fruit (1.5–2 inches) featuring a bumpy, pink-to-red leathery rind that peels away to reveal sweet, translucent-white, grape-like flesh. It is highly aromatic with a floral, slightly acidic flavor, surrounding a single inedible brown seed. Lychee is rich in vitamin C and used in desserts and drinks.
