I’ve been doing some native / foraged foods and they always have disclaimers about plants high in oxalates might cause kidney stones. They wild grown foods typically contain 10 to 100 times more concentrated vitamins, minerals and other both helpful and unhelpful components per ounce than traditional vegetables.

The real issue isn’t the kidney stones but that oxlatic acid is an anti-nutrient that stops the body from absorbing calcium. But there is not issue unless you eat in large quantities daily. It grows in my yard as a weed so I like to eat some of it while I am weeding. Its delicious and besides its anti-nutrient effect on calcium pretty healthy for you.
