[Wikipedia] As Food: The leaves of Oxalis oregana are eaten by the Cowlitz, Quileute and Quinault peoples. Like spinach, they contain mildly toxic oxalic acid, which is named after the genus.[7] They are safe to eat in small amounts for those with no oxalate-related conditions.[8] (link added by Mary Ann Machi)
