Hamamelis virginiana Health effects and herbal facts

Known as
witch-hazel

Hamamelis virginiana, known as common or American witch-hazel, is a species of witch-hazel native to eastern North America, from Nova Scotia west to Minnesota, and south to central Florida to eastern Texas. It is a small, deciduous tree growing up to 6 m tall, often with a dense cluster of stems from its base. The bark is light brown, smooth, scaly, inner bark reddish purple. The branchlets are pubescent at first, later smooth, light orange brown, marked with occasional white dots, finally dark or reddish brown. The foliage buds are acute, slightly falcate, downy, light brown. The leaves are oval, 3.7–16.7 cm long and 2.5–13 cm broad, oblique at the base, acute or rounded at the apex, with a wavy-toothed or shallowly lobed margin, and a short, stout petiole 6–15 mm long; the midrib is more or less hairy, stout, with six to seven pairs of primary veins. The young leaves open involute, covered with stellate rusty down; when full grown, they are dark green above, and paler beneath. In fall, they turn yellow with rusty spots. The leaf stipules are lanceolate, acute; they fall soon after the leaf expands.
