I just wanted to add the signs to look for if you've eaten a carambola and shouldn't have.
Here are some signs you've got starfruit intoxication: You might start with hiccups that never stop. Vomiting is common, numbness in limbs, muscle twitches, convulsions, insomnia and confusion are the clues you may have star fruit intoxication.
Remember that carambola recipes are delicious and very common. However, if you suffer from a kidney problem, this fruit should be considered one that you should avoid.
