Fruit of the vine-like cactus plant and known also as pitaya, strawberry pear, or paradise fruit, which is a native of Mexico, South America but widely cultivated in Southeast Asia.
The fruit flesh, which is eaten raw, is mildly sweet and low in calories. The flavor is sometimes likened to that of the kiwifruit and may be converted into juice or wine; the flowers can be eaten or steeped as tea. Sesame seed-sized seeds are embedded throughout the flesh. Rich in antioxidant.
