The toxicity debate over comfrey is ongoing. Some herbalists use it without worry while others don’t. It is interesting to note that the negetive toxicity studies done on comfrey tend to be done using very high doses, or do not represent the effect that oral ingestion or topical use would have. For example injecting phytochemcals from this plant directly into the blood stream would not be the same as eating the leaves of this plant.
