​Comfrey's use dates back centuries to at least the time of the ancient Greeks. During the Middle Ages comfrey was a widely cultivated herb found extensively in the gardens of monasteries. Throughout the 1700's and 1800's comfrey was also a popular herb grown in many gardens across Europe as well as America. Sometime during the late 1970's however research revealed that comfrey when taken internally can cause severe liver damage so it has lost popularity and internal use is even banned in many countries. Applications in the from of ointments, poultices, or creams are still considered safe though. Comfrey can still be found growing wild in central Europe, and the eastern United States as well as  a few western states.

And specifically, in those with breast cancer, people choosing alternative medicine were 5.68 times more likely to die within five years.[18]
