What primary compound in sorrel is cited as the most widely cited reason for consumption caution?

Answer

Oxalic acid

The most significant chemical component necessitating caution when consuming sorrel, especially in concentrated forms, is oxalic acid. This naturally occurring compound has a high concentration in the plant. When ingested in excess, oxalic acid is known to react readily with divalent cations found in the body. The primary chemical reaction that leads to adverse health effects involves this acid binding strongly with calcium. This binding forms insoluble precipitates, specifically calcium oxalate crystals. These crystals are problematic because they are the fundamental structural components of calcium oxalate kidney stones, making oxalic acid the central focus of warnings regarding excessive sorrel intake.
