                                Over 80% of all kidney stones are composed primarily of calcium oxalate. Certain plants contain high levels of a naturally occurring compound called oxalic acid, or oxalate, which can contribute to the formation of these stones and interfere with mineral absorption. Knowing what plants have oxalic acid and require caution is vital for those with specific health concerns, but most people can consume them in moderation.
