Frequently Asked Questions about Starfruit

Is starfruit safe for everyone?

No. Individuals with chronic kidney disease (CKD) or kidney stones should avoid starfruit due to its caramboxin and oxalic acid content, which can be toxic when not properly filtered by the kidneys.

What is caramboxin?

Caramboxin is a neurotoxin found in starfruit. In healthy individuals, the kidneys filter it out, but it can cause severe neurological symptoms in those with renal impairment.
