Common Comfrey (Symphytum officinale)
This highly valued medicinal herb bears pink, purple, and white flowers and is best used as poultice. Comfrey contains allantoin which facilitates cell division, making it extremely valuable for healing wounds. Due to pyrrolizidine alkaloids in comfrey, there is concern for hepatic toxicity; therefore, it should be applied externally only.
