Cautions:
1. Not used during Pregnancy or while breastfeeding
2. Toxic in overdose or long-term use. Should not be used in those with Liver disease.

Comfrey, like other Pyrrolizidine-alkaloid (PA) containing plants has become controversial and its internal use is banned in a number of countries. In parts of Europe, Comfrey has been traditionally eaten as a food where there are reportedly no greater incidences of Liver disease. However, research has demonstrated potential Hepatotoxic effects. In general, Comfrey is traditionally used for short periods of time, especially as a wound herb. In these cases, use for 2–3 weeks should pose no risk. However, it is best avoided in the very young, elderly, while pregnant and breastfeeding, and in those with Liver disease. Its topical use is regarded as safe.

According to Hoffman, "Between 85% and 97% of the PAs in Symphytum officinale (True/Common) commonly grown in American gardens are built around the less toxic retronecine monoester. However, Russian comfrey (Symphytum peregrinum), contains higher levels of the diester, which, is known to have a greater toxicity." (See here). Further, echimidine is the most toxic PA in comfrey species and is found in higher amounts in Russian and Prickly Comfrey, not S. officinalis.

It is also important to note that toxic alkaloids are found in higher amounts in the root, therefore making the leaf a safer option for internal use.


An exhaustive review of literature found 8 suspected cases of adverse events from oral intake of Comfrey. However, as the authors noted, other factors such as medication taken simultaneously or incorrect identification could not be ruled out. The authors stated "
Based on these case reports, the evidence of harm caused by these plants is weak." (see here)

Toxicity:
–Oral toxicity study of certain plant extracts containing pyrrolizidine alkaloids
–The comparative toxicity of a reduced, crude comfrey (Symphytum officinale) alkaloid extract and the pure, comfrey-derived pyrrolizidine alkaloids, lycopsamine and intermedine in chicks (Gallus gallus domesticus).
–Metabolism, genotoxicity, and carcinogenicity of comfrey.
–Hepatotoxicity of Pyrrolizidine Alkaloid Compound Intermedine: Comparison with Other Pyrrolizidine Alkaloids and Its Toxicological Mechanism
–
Safety of medicinal comfrey cream preparations (Symphytum officinale s.l.): The pyrrolizidine alkaloid lycopsamine is poorly absorbed through human skin.

Main Preparations used:
Distilled Water, Conserves of the Flower, Conserve of the Root, Candied Root, Syrup of the Root, Extract of Comfrey (including the ‘Bloody Extract’), Powder, Decoction and Mucilage
