Dr. Christopher used Comfrey in many of his formulas. He recognized the benefits, and powerful healing agents of Comfrey. A good majority of his formulas contained Comfrey. However, recently the FDA and the FTC decided that Comfrey was a dangerous herb, because when it is a young plant it has a high Pyrrolizidine alkaloid content. This has led the FTC and the FDA to believe that Comfrey is dangerous. Dr. Christopher never had a problem with Comfrey, and we have yet to hear of someone who has been damaged by it. Nevertheless, the Dr. Christopher Company had to remove Comfrey from the internal formulas. Comfrey is still used in the external formulas.
During this time, we put the following information together to submit to the FTC, in support of Comfrey. This information does get very technical at times.
