There are so many cool uses for witch hazel.
According to Wikipedia, witch hazel is “an astringent produced from the leaves and bark of the North American Witch Hazel shrub (Hamamelis virginiana), which grows naturally from Nova Scotia west to Ontario, Canada and south to Florida, and Texas in the United States.
This plant was widely used for medicinal purposes by American Indians. The witch hazel extract was obtained by steaming the twigs of the shrub. The main constituents of the extract include tannin, gallic acid, catechins, proanthocyanins, flavonoids (kaempferol, quercetin), essential oil (carvacrol, eugenol, hexenol), choline, saponins, and bitters. Distilled witch hazel sold in drug stores and pharmacies typically contains no tannin.”
