This snippet from the website explains Comfrey's value to the Organic Gardener...

“Comfrey is a particularly valuable source of fertility to the organic gardener. It is very deep rooted and acts as a dynamic accumulator,[6] mining a host of nutrients from the soil. These are then made available through its fast-growing leaves (up to 1.8-2.3 kilograms (4.0-5.1 lb) per plant per cut) which, lacking fibres, quickly break down to a thick black liquid. There is also no risk of nitrogen robbery when comfrey is dug into the soil as the C:N ratio of the leaves is lower than that of well-rotted compost. Comfrey is an excellent source of potassium, an essential plant nutrient needed for flower, seed and fruit production. Its leaves contain 2-3 times more potassium than farmyard manure, mined from deep in the subsoil, tapping into reserves that would not normally be available to plants.” - Source: Wikipedia
