This beautiful fruit looks very appetizing. Moreover, the carambola’s leaves and flowers are well known for their amazing healing properties. Juicy and crisp, it would taste good to anyone who enjoys fruit. However, you shouldn’t eat more than a few pieces of it at a time. In fact, star fruit contains high amounts of oxalic acid which is harmful to individuals suffering from kidney disease. Carambola also has a neurotoxin capable of causing neurological disorder and hallucinations.
