A sweet-tasting herb that looks a little like a scarlet-colored raisin, lycium is considered a blood tonic.  It helps improve vision, especially night vision, builds strength in the legs, and calms the heart and nervous system.  It also is frequently used as a sexual tonic and in mild forms of diabetes.  It seems to blend with other herbs exceptionally well and can be regularly used in cooking soups and stews.
