Comfrey is a shrub that grows in parts of Europe, Asia, and North America. It can grow up to 5 feet tall. It produces clusters of purple, blue, and white flowers, and it’s famous for its long, slender leaves and black-skinned roots. The long, pervasive roots are more potent than the leaves but have higher levels of a constituent toxic to the liver. Typically used in topical ointments, creams and salves. (.25 oz)
