Caption: Comfrey flower petal. Coloured scanning electron micrograph (SEM) showing papillae on a petal from a comfrey (Symphytum officinale) flower. Papillae are projections from epidermal cells. They are often swollen, and covered in wax to reduce water loss. Comfrey is a perennial herb that grows wild in North America and is cultivated in many countries for its supposed medicinal properties. The leaves and roots are believed to be able to treat fever, inflammation, wounds and broken bones. However, taking it by mouth can be dangerous due to the presence of pyrrolizidine alkaloids, which can cause liver damage.
