American Witchhazel
Hamamelis virginiana
Hamamelis virginiana, commonly known as witch hazel, originates from North American traditions. Traditionally, it has been used for its astringent and anti-inflammatory properties, particularly for skin conditions such as hemorrhoids and minor burns. Scientific evidence suggests that extracts from both the leaf and bark of Hamamelis virginiana possess strong antioxidant and anti-inflammatory effects, with the bark extract showing additional activity against enzymes involved in collagen degradation. While topical applications have shown promise, a study comparing breast milk to witch hazel cream for diaper dermatitis treatment found mixed results due to baseline severity differences among participants. In zebrafish models, Hamamelis virginiana significantly normalized antioxidant enzyme activities and reduced oxidative stress markers following ethanol exposure. No major safety concerns or drug interactions have been recorded in relation to this plant.
