We love learning all about the plants in our garden and in the wild. Beyond the obvious edible uses of the vegetables we grow, there’s so much more to know. Take sorrel, Rumex acetosa, for instance. There are many proven and traditional sorrel benefits this oft overlooked plant has to offer.
Sorrel is a perennial herb that belongs to the Polygonaceae family. We have perennial French sorrel growing in our garden and the wild southern wood sorrel in the woods all around us. Both have edible and medicinal benefits.
