Black Cohosh is a tall, stately wildflower of eastern forests, producing long wands of white flowers that attract flies through a foul odor. It is one of the most commercially harvested medicinal plants in North America, used for menopausal symptom relief, leading to population declines in some areas. The seeds are dispersed by birds after ripening.
