Comfrey is a commonly used herbal medicine with a long and proven history in the treatment of various complaints. The root and the leaves are used, the root being more active, and they can be taken internally or used externally as a poultice. Comfrey is especially useful in the external treatment of cuts, bruises, sprains, sores, eczema, varicose veins, broken bones etc, internally it is used in the treatment of a wide range of pulmonary complaints, internal bleeding etc. The plant contains a substance called 'allantoin', a cell proliferant that speeds up the healing process. This substance is now synthesized in the pharmaceutical industry and used in healing creams.

The root and leaves are anodyne, astringent (mild), demulcent, emollient, expectorant, haemostatic, refrigerant, vulnerary. Some caution is advised, however, especially in the internal use of the herb. External applications and internally taken teas or tinctures of the leaves are considered to be completely safe, but internal applications of tablets or capsules are felt to have too many drawbacks for safe usage.

The leaves are harvested in early summer before the plant flowers, the roots are harvested in the autumn. Both are dried for later use.

A homeopathic remedy is made from the fresh root, harvested before the plant flowers. Ths has a very limited range of application, but is of great benefit in the treatment of broken bones and eye injuries.

Young leaves - cooked or raw. The leaf is hairy and the texture is mucilaginous. It may be full of minerals but it is not pleasant eating for most tastes. It can be chopped up finely and added to salads, in this way the hairyness is not so obvious.

Young shoots can be used as an asparagus substitute. The blanched stalks are used.

A tea is made from the dried leaves and roots. Older leaves can be dried and used as a tea.

The peeled roots are cut up and added to soups. The roasted roots are used with dandelion and chicory roots for making coffee.

Known Hazards: This plant contains small quantities of a toxic alkaliod which can have a cumulative effect upon the liver. Largest concentrations are found in the roots, leaves contain higher quantities of the alkaloid as they grow older and young leaves contain almost none. Most people would have to consume very large quantities of the plant in order to do any harm, though anyone with liver problems should obviously be more cautious. In general, the health-promoting properties of the plant probably far outweigh any possible disbenefits, especially if only the younger leaves are used.
