Comfrey

Comfrey (Symphytum officinale)

Comfrey is widely known for its remarkable healing properties for ulcers, broken bones and soft tissue damage. It has cell proliferant properties which promote speedy wound healing, for which it can be used both internally and externally.

It’s also very soothing for the mucous membranes, as well as being an expectorant, so it is excellent to include in any respiratory herbal blend. It also improves circulation, and is helpful for treating arthritis.

“The Comfrey Debate:

Regrettably, the internal use of Comfrey has been a much misunderstood and frequently controversial subject since the late 1960’s. The presence of a group of compounds contained in Comfrey called pyrrolizidine alkaloids (PA’s) instigated concern during a Japanese study on lab rats in 1968, which involved injecting high concentrations of isolate symphytine alkaloid in sufficient dosages that it would represent a staggering 33% of a rat’s daily food intake!

Herbalists argue that this is a totally unrealistic representation – as to begin with, in order to replicate the experiment in horses, they would have to ingest 150kg of isolate symphytine daily, and because symphytine only represents a tiny portion (5%) of total PA’s, this would mean a horse would have to consume a staggering 8,33 tonnes per day of dried comfrey! To add further perspective, PA’s are not uncommon in many foodstuffs – for example, both red wine and dark chocolate contain concentrations of PA’s.

Herbalists argue that:

- The concentration of symphytine used in the trials was completely unrealistic
- Injected substances can have a vastly different effect on the body, compared to those delivered orally
- Substances given in extracted isolation can behave very differently than if they are delivered in a balanced whole-herb form e.g. Aspirin is extracted from Meadowsweet. Aspirin aggravates gastric ulcers in its extracted form, but Meadowsweet in its whole form is one of the best ulcer healing herbs
- The species of Comfrey used in the trials were not specified, and the presence of symphytine varies greatly depending on species, and parts of the herb used (the root has a far higher concentration of symphytine than the leaves). Prickly Comfrey (Symphytum asperum) and Russian Comfrey (Symphytum x uplandicum) contain a far higher concentration of PA’s than English (also known as Common) Comfrey (Symphytum officinalis). The presence of symphytine in English Comfrey leaves is barely traceable.
- The detractors also ignore the history of Comfrey’s safe and extensive usage as a bulk fodder crop for both cattle and horses (much revered by farmers) in Europe since the 1840’s.”
