I just bottled my wood sorrel infused apple cider vinegar. I have it growing everywhere and I need to weed it constantly so I usually eat it. I do a few times per year to grab all of it and make it into a vinegar. Its one of my favorites vegetables / herbs
laxative effect is unpleasant at worst, the real issue is that they can contribute to kidney stones! if you're at all at risk of getting kidney stones then don't eat them!
Oh wow I don't think I've ever seen this outside before (east coast US) almost always in house plants potted. And usually the purple stringy variety. Are they related??
