This is a plant that is common in watery areas of Europe, Great Britain, and parts of Western and Central Asia, greatly valued in agriculture as a source of concentrated nutrients for animal feed and in organic fertilizers.
Comfrey is best known for its component allantoin, a small hormone-like molecule that is used in many topical products to stimulate cell growth and tissue repair for broken bones as well as many other conditions including wounds, sprains, ulcers, burns, arthritis and back pain, rashes, bleeding hemorrhoids, and herpes lesions. The plant is a rich source of calcium, potassium, phosphorus, vitamins, triterpenes, chlorophyll, silicic acid, and trace minerals.
Despite a long history of internal use for Comfrey’s anti-inflammatory, fever reducing, antihemorrhagic, expectorant, astringent, and demulcent effects in healing respiratory and digestive disorders, the presence of hepatotoxic pyrrolizidine alkaloids (mainly in Comfrey root) have led to a general consensus that its employment is best confined to external applications such as salves, oils, poultices, and fomentations.
