Feverfew is a daisy-like perennial that can be found growing throughout the United States and Canada. As the name suggests, it was historically used for fevers, though current research is studying its efficacy for head health. Feverfew has been added to food to cut the greasy taste, but is extremely bitter and disagreeable to most palates. Used in teas, tinctures, and decoctions. (.5 oz)
