What is Witch Hazel Extract?
Witch Hazel, an ornamental shrub that grows 6 à 30 feet (1.8 à 9 m) in height. “Witch” comes from the Old English word “wych,” used to describe a plant whose branches bend easily; “hazel” refers to the flowers, which are dull yellow or golden-yellow.Some varieties have orange or red flowers. Depending on the species, the flowers appear in autumn, winter, or early spring; they are particularly resistant to cold weather. The leaves are oval and have toothed edges.
Witch hazel extract is a powerful ingredient commonly seen in skincare products like toners. It is derived from the witch hazel plant (also known by its latin name Hammamelis virginiana), which is a flowering shrub that grows throughout North America and Asia. The plant sort of looks like a small tree with yellow flowers and is known around the world for its medicinal properties. Though you might be inclined to think that witch hazel extract is distilled from the flowers, it’s actually made from the shrub’s leaves and bark. To create the extract, the bark and leaves are distilled in either water or alcohol (more on that below) to draw out the active chemical compounds of the plant (AKA the plant’s magical properties).
