How should I use comfrey ()?

The use of comfrey in cultural and traditional settings may differ from concepts accepted by current Western medicine. When considering the use of herbal supplements, consultation with a primary health care professional is advisable. Additionally, consultation with a practitioner trained in the uses of herbal/health supplements may be beneficial, and coordination of treatment among all health care providers involved may be advantageous.

Since the use of comfrey has been associated with serious liver damage, ingestion of comfrey is not recommended. The FDA has issued a warning to consumers that the use of comfrey may present a serious health hazard. Also, the topical application of comfrey preparations to broken skin should be avoided.

If you choose to use comfrey, use it as directed on the package or as directed by your doctor, pharmacist, or other health care provider.
