② Healing Intestinal Inflammation and Blocking 'Oxalate Hyperabsorption' When oxalate is excreted, the intestinal wall is scratched by microscopic crystals, causing inflammation. This leads to a phenomenon called 'leaky intestines,' where gaps between cells widen. If the intestines are damaged in this way, oxalate, which should be excreted through stool, is excessively reabsorbed into the bloodstream through the intestinal wall (hyperabsorption), creating a vicious cycle of systemic pain.
