How the form changes the number: preparation is the real variable across this family. Boiling leaches a meaningful share of soluble oxalate into the cooking water — commonly 30-50% for plant foods — while raw and dry-heat forms keep essentially all of it, so the same base food can land in different brackets depending on how it is cooked. This page tracks Sorrel (Raw) at 405 mg per serving, at the high end of the family. Related forms in this family: Sorrel (Boiled 15 min) (303 mg).

Can I eat Sorrel if I pair it with dairy?
Yes, it helps. Calcium from food (yogurt, cheese, milk) binds oxalate in your gut so less reaches your kidneys. With Sorrel, having dairy at the same meal is a smart move. Not supplements though — those work differently.
