 Perennial herb, 0.30-1m high, native to Eurasia, introduced to North America; leaves large, hispid, broad lanceolate, ground leaves long petioled, others going up the stem with the base, forming wings; corolla tube reddish-violet or white, calyx nearly half as long as corolla.
+"In dried leaves 0.02 to 0.18 and in the roots 0.25 to 0.29% alkaloids resp. their N-oxides were detected. The alkaloids include intermedine, lycopsamine, their 7-acetyl derivatives, symlandine, symviridine, myoscorpine, and symphytine. The presence of the alkaloids (echinatine, heliosupine N-oxide, heliotrine, lasiocarpine, and viridiflorine) isolated and characterized by a Russian and Polish working group by means of paper
+chromatography could not be confirmed. A possible risk associated with the consumption of Symphytum in humans was repeatedly reported and in medical literature several cases of intoxication attributed to Smphytum and comfrey are described. In animal tests acute toxic effects were detected in rats and goats." \\

 "Since the pyrrolizidine alkaloids are known to be hepatotoxic, consumption of herbal teas made from comfrey leaves may be ill-advised. The concentration of pyrrolizidine alkaloids in such teas may be underestimated substantially unless the concentration of N-oxides is taken into consideration." \\
