Feverfew Extract Average Plant extracts No known benefits Feverfew Extract description Feverfew extract can be potentially skin sensitising if a specific constituent of the feverfew plant known as parthenolide (technically, sesquiterpene lactone) is present. If the parthenolide is removed from feverfew, it is not a problem for skin and may actually be beneficial because parthenolide-free feverfew has potent skin-soothing properties and can help to diminish redness. If a skin care product contains feverfew, it’s best to contact the company to confirm that the feverfew in their products is parthenolide-free. Note: All Paula’s Choice products are parthenolide-free. Feverfew also goes by the names _Tanacetum parthenium_ and _Chrysanthemum parthenium._ Related ingredients: Chrysanthemum Parthenium (Feverfew) Extract Chrysanthemum Parthenium Flower Extract Tanacetum Parthenium (Feverfew)
