Like several other plants of the family Oxalidaceae, its fruits are rich in oxalic acid, which is toxic in high concentrations.
There have been reports of intoxication in dialysis and uremic patients caused by a neurotoxin called caramboxin^[13][14] present in the fruit. Such toxin is normally filtered by the kidneys, but patients in dialysis or suffering from kidney deficiencies may show severe symptoms, in a few cases fatal,^[15] after drinking the fruit juice.
