Issued also in French under title: Fiche d'information sur la consoude. "For centuries, the roots and leaves of the comfrey plant have been used for their healing properties. Historically comfrey was felt to help heal broken bones and wounds - this explains its derivation from the Latin word "conferre" meaning to bring together. There are several different species of comfrey and two of them contain compounds known as unsaturated pyrrolizidine alkaloids (UPAs) that have been shown to cause liver damage. One of these dangerous alkaloids is echimidine and it is found in both Prickly comfrey and Russian comfrey. While some comfrey products do not contain harmful UPAs, not all manufactures identify the species of comfrey in their products and until this changes Health Canada has advised Canadians to avoid using all of these products."--What is it? gccst Medical products gccst Medicinal plants Canada.
