sorrels are generally thought to be safe or non-toxic, but they should be fed in small amounts and not on a regular basis because they are very high in oxalic acids (that's what makes them sour) which blocks absorption of minerals including calcium. It may help to steam them to inactivate some of the oxalic acids. Spinach is another one hight in oxalic acid or oxalates.
