Witch hazel is a shrub or small tree belonging to the Hamamelidaceae family. Known scientifically as Hamamelis virginiana, it is native to North America and is recognized for its fragrant yellow flowers that bloom in late fall. The bark and leaves of the plant are often used to make extracts for cosmetic and medicinal purposes.
