Properties:

Symphytum is an erect perennial growing in most damp areas of the United Kingdom, Europe, western Asia and the U.S.A. It is a vigorous plant with broadly lanceolate leaves up to 30cm long, which taper into a point. The leaves arise as a rosette from the ground, have a rough texture, and are covered with short stiff hairs. The rosette supports a tall, erect flowering stem up to 1.5m tall, covered with sessile opposite leaves and bearing forked stalks which support one-sided racemes of pedicillate bell-shaped mauve or white flowers which curve downwards. The fruits are four greyish-brown nutlets. The rhizome is quite short and thick with black, finger-thick branched roots. The flowering period is from May to July. Russian comfrey (S. peregrinum), widely grown for its horticultural benefits, can also be used medicinally.
Dosage: Dried leaf: 2-8g or by infusion,Liquid Extract Leaf: 1:1 in 25% alcohol, 2-8ml,Ointment Root: 10-15% extractive in ointment base.

Safety and Toxicity:

The alkaloids of Russian comfrey caused chronic liver damage and pancreatic islet cell tumors after 2 years of use in animal models. Eight alkaloids have been isolated from Symphytum x uplandicum .Alkaloid levels ranged from 0.003% to 0.115%, with highest concentrations in small young leaves.
Hepatic veno-occlusive disease has been related to Symphytum ingestion at high doses over long periods, and the effects of the alkaloids are cumulative. Topical application is safer and more effective for arthritis than internal administration. External application need not be restricted.
