Witch Hazel Extract
Witch Hazel is also known by the names Winterbloom, Snapping Hazel, Virginia Witch Hazel, Hazelnut, Tobacco Wood, Striped Adler, and Spotted Alder. Witch Hazel is a shrub native to North America, and now also grows in Europe.
The primary chemical constituents of Witch Hazel include tannins (gallic acid), catechins, proanthocyanins, flavonoids (kaempferol, quercitin), essential oil in the leaves (carvacol, eugenol, hexaenol), choline, saponins, and bitters. Tannins and volatile oils are the main active constituents. The flavonoid content helps heal damaged blood vessels and contributes to the plant's astringent properties. The antiseptic, anti-inflammatory and anesthetic activity makes Witch Hazel an ingredient in over-the-counter hemorrhoid products.
