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.

What the science says
- The study found that bicycle proteins from Hamamelis virginiana aphids exhibit saposin-like folds, with structural diversity suggesting they target various plant processes.
- Both Hamamelis virginiana leaf and bark extracts showed strong antioxidant and anti-inflammatory effects, with the bark extract additionally inhibiting collagenase and elastase.
- Topically applied breast milk showed greater improvement in diaper dermatitis compared to a Hamamelis virginiana cream, though baseline severity differences were noted.
- Hamamelitannin from Hamamelis virginiana significantly normalized oxidative stress markers and reduced inflammatory responses in ethanol-exposed zebrafish larvae.
