Epilobium Angustifolium Flower/Leaf/Stem Extract

Epilobium Angustifolium Flower/Leaf/Stem Extract is a whole-plant extract from fireweed (also known as rosebay willowherb), derived from flowers, leaves, and stems. The key bioactive is oenothein B, a dimeric ellagitannin that has been extensively studied as a 5α-reductase inhibitor (reducing sebum production) and anti-inflammatory. The extract also contains flavonoids and phenolic acids with antioxidant activity. Used in Korean cleansing and sensitive-skin formulas targeting oil control and inflammation.

  • Tannins and flavonoids from the whole-plant extract provide anti-inflammatory, antioxidant, and mild astringent effects; the anti-inflammatory activity is well-supported by in vitro and in vivo data
