Hamamélis de Virginie
Hamamelis virginiana · American Witchhazel
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.

Ce que dit la science
- L'étude a révélé que les protéines des vélos des tarentelles de Hamamelis virginiana présentent des pliages similaires à ceux des saposines, avec une diversité structurelle suggérant qu'elles ciblent divers processus végétaux.
- Les extraits de feuille et de peau de Hamamelis virginiana ont montré des effets antioxydants et anti-inflammatoires forts, avec l'extrait de peau qui inhibe en outre la collagénase et l'elastase.
- Le lait maternel appliqué topiquement a montré une amélioration supérieure chez les dermatites du bassin par rapport à une crème d'Hamamelis virginiana, bien que des différences de sévérité initiale aient été notées.
- Le hamamilétan de Hamamelis virginiana a significativement normalisé les marqueurs du stress oxydatif et réduit les réponses inflammatoires chez les larves de zèbrawfish exposées à l'éthanol.
