Blue Cohosh (Caulophyllum thalictroides)

Witch Hazel (Hamamelis virginiana)

About

Blue cohosh is an upright perennial herb reaching 3 feet in height, with large three-lobed leaves, yellow to purple flowers, and striking blue berries. It grows wild in much of eastern North America from Manitoba to Alabama, preferring woodland valleys and damp, north-facing slopes. The name 'cohosh' comes from the Algonquin language, and the plant was a popular remedy among many Native American tribes. Though taken by both sexes for genitourinary issues, it was primarily valued as a women's herb, and that tradition continues in modern herbal practice.

Witch hazel (Hamamelis virginiana) is a small deciduous tree or shrub, often up to 16 ft (5 m), producing coarsely toothed leaves and distinct, ribbonlike yellow flowers in autumn or winter. Its bark and leaves are highly astringent, making witch hazel widely used for skin, varicose veins, and hemorrhoids.
