Abstract

New studies have shown the mechanism by which the star fruit (Averrhoa carambola) becomes toxic to individuals with chronic kidney disease (CKD). The aim of this study was to review the current literature on the topic. This is a review article, with publications from 2000 to 2014 available in scientific database. There are reports that neurotoxicity is due to the presence of oxalate in star fruit, but recent findings show that the neurotoxic effect of the toxin is by caramboxin, which appears to inhibit the GABAergic system which is the major inhibitory system in the central nervous system (CNS), involving changes as sobs and confusion, to more serious conditions such as seizures and death. It is important to multidisciplinary action to alert patients with CKD as the prohibition of the star fruit consumption.
