    Thanks, excellent post – I just got one of these as a volunteer in my garden, and as I eat weeds (dandelions especially) I was interested in this as an edible – glad to know it has less oxalic acid than a lot of other things I eat :)

    Great post, Lisa! Goose and Binky eat sorrel(not wood) raw all summer long. I, too, have read the warnings. I just make sure they only eat 2 or 3 leaves a day and not every day. But they do love it!

    I’m thinking about starting a weed garden in one of our co-op school’s garden boxes, so I love all your posts about edible wild plants. :-) I’m not sure I’m going to be able to convince anyone to *add* weeds to our garden though. :-)

    Leave it to Lisa to teach me what I’ve been calling clover are actually wood sorrel. Good to know! We have lots!

    I think it’s so funny that I know plants by look and sometimes a common name but don’t know what it really is and what it’s good for. Thanks for sharing the science too.

    So all this time I’ve been searching for a 4 leafed cover, it’s been in a sorrel patch?! As kids we always sucked the stems of the little yellow flower for their sweet tangy taste.
    Glad to have my clover misdiagnosis finally sorted out… no wonder I’ve never found a 4 leafed clover even though I’ve searched for hours and hours!
    Blessings and magic.

    We love to munch on wood sorrel. Susun Weed suggests eating foods high in calcium with your leaves that are high in oxalic acid, because it interferes with calcium absorbtion.

    I have suffered from kidney stones for years and had no idea there was a link to oxalic acid. Thanks for this information :)

    I just added a link to this post in the wild edibles post I did earlier this summer.


    Love all you write about over here Lisa (smile).

    No! Not too much information. I’ve actually wondered about this myself and now you’ve answered it for me. My kids love eating this stuff raw all summer from the yard and garden.

    Oxalic acid! So that’s why my kidney doctor told me to stop eating my favorite spinach salad. Yes, I get kindey stones, four times so far. When he started listing things I couldn’t have I said, “Just tell me what I CAN have.” Thanks for making it so easy to understand. You’re a true gem. xxoo

    Oh no! My girls have been eating tons of chives from the garden all summer long! (but they seem to be okay so I guess I won’t worry too much.) Very much enjoying your edible wild foods posts. But why is lambsquarters highlighted bright red?? I see it has a high number, but I’m not sure what your columns mean… and lambsquarters is one of my favorites…

    Thank you for that great information :-)

    Lady, you can go on about wood sorrel all you’d like – we’ll listen! Eliza loves sorrel and looks for it everywhere – I’ll often hear her telling someone (like my dad!) the difference between clover and sorrel.
