Large-flowered Comfrey

(Symphytum grandiflorum)

This species of comfrey was mentioned by many medieval botanists. The herbalists used it to treat fractures, internal bleeding, and even to restore the hymen, but it was all to no avail. In 2001, US health officials warned of the dangers of using herbal products containing comfrey. The plant was also excluded from many European lists of medicinal herbs.
