The Science Behind Witch Hazel Extraction
Chemical Composition of Witch Hazel
Witch hazel, scientifically known as Hamamelis virginiana, is a botanical treasure trove of beneficial compounds. The plant's bark and leaves contain a complex mixture of phytochemicals, including tannins, flavonoids, and volatile oils. Tannins, particularly hamamelitannin and gallic acid, are the primary active constituents, contributing to witch hazel's astringent and anti-inflammatory properties. These polyphenolic compounds interact with proteins in the skin and mucous membranes, creating a protective barrier and reducing inflammation. Flavonoids, such as quercetin and kaempferol, provide antioxidant benefits, neutralizing free radicals and supporting overall skin health. The volatile oils, including carvacrol and eugenol, impart witch hazel's characteristic scent and possess antimicrobial properties.
