Carambola is the fruit of the Averrhoa carambola tree, belonging to the Oxalidaceae family. It is native to Southeast Asia but is now cultivated in many tropical and subtropical regions around the world, including the Philippines, India, Malaysia, Israel, the United States (notably Florida and Hawaii), and parts of Africa and the Caribbean.
Its flavor is a harmonious blend of sweet and tangy flavors, often compared to a mix of apple, pear, and citrus fruits like lemon or lime. The texture is crisp and juicy, similar to apples or grapes. The flesh is firm yet succulent, making it refreshing to eat.
Carambola, is not native to St. Croix. Its origins trace back to Southeast Asia, in countries such as the Philippines, Malaysia, Indonesia and India.
While there are numerous cultivars of carambola, the Arkin carambola, also known as the Arkin star fruit, is the variety that is grown in Florida and the Caribbean.
Carambola is renowned for its star-like shape when sliced crosswise, making it a popular choice for garnishes and decorative presentations. The size typically ranges from 5 to 10 centimeters (2 to 4 inches) in length.The color rangesfrom bright green to yellow or yellow with a reddish blush as it ripens. The skin is smooth and waxy, edible but can sometimes be slightly tart or bitter if the fruit is underripe.

While carambola is generally safe for consumption, there are some considerations to keep in mind: Carambola contains high levels of oxalates and other neurotoxins, such as caramboxin and betacyanins. Excessive consumption can lead to oxalate kidney stones and kidney damage, and neurological symptoms, especially in individuals with pre-existing kidney conditions. Some people may experience allergic reactions, including itching, swelling, or difficulty breathing. If you suspect an allergy, discontinue consumption and seek medical attention. Caramboxin is a unique neurotoxin found almost exclusively in carambola (starfruit). It is a branched-chain amino acid derivative that contributes to the fruit’s toxic effects in susceptible individuals.
Carambola can interact with certain medications, such as those for hypertension (e.g., ACE inhibitors). Individuals on medication should consult healthcare providers before adding carambola to their diet.
