Health Benefits of Comfrey


This Amazing Plant has So Many Uses

for Joint Pain & Bone Fractures

Dioscorides, an ancient Greek botanic physician, documents the use of Comfrey in treating the armies of Alexander the Great. The wild Comfrey, Symphytum comes from the Greek word “syumphuo”meaning “to make grow together”, and has been known to herbalists for over 2,000 years. One of the medicinal properties of the comfrey plant is that it is mucilaginous, meaning that it secretes mucilage which can be sticky (a bit like Aloe Vera). Comfrey has also a very high content of allantoin, a substance that promotes new skin cell growth, reduce inflammation, relieve joints in degenerative arthritis and maintain healthy skin. Comfrey contains Vitamin B12, potassium, sulphur, calcium, iron, phosphorus, Vitamin A, Vitamin C, Vitamin B-complex, selenium, iron, germanium and mucilaginous fibre. It is also an excellent source of protein. Comfrey, while considered an important herbal medicine, is controversial due to its toxic components, called pyrrolizidine alkaloids (PAs), which is thought to damage the liver when ingested orally.  For this reason, internal use of Comfrey in supplements was banned in the US in 2002. However, new studies including this study suggests that Comfrey toxicity has largely been overrated. As a side note, in my home country, France, many people, including my family, eat and cook Comfrey without experiencing any sides effects. Comfrey also showed good results wen used on children aged 3 and over.

As a general rule, before ingesting Comfrey it’s better to first ask your naturopathic doctor. As far as my experience, as I said, I did eat Comfrey while growing up in France but stopped when I moved to the US, because it was less accessible. I also have a lot of experience using it topically on wounds and can testify to its outstanding efficacy.
