Sheep’s sorrel is a perennial weedy herb that is native to Eurasia and also known by several other common names, such as sour grass, red sorrel and field sorrel.
As persistently invasive as the plant is in most of the United States, it does have redeeming culinary value. The herb lends a lemony, tangy flavor to foods and tea blends. It is also one of the herbs found in the classic Essiac tea formula.
