Comfrey is being considered by some as weed but it is far away from being that…
The large leaves provide shade and shelter for small animals, birds, insects and frogs while pollinators love the flowers..
Comfrey has thick far reaching roots which access minerals that are deep in the soil and make the plant rich in potassium and nitrogen and has therfore become a important plant for organic gardening. The leaves can be cut several times a year to make an organic slug control, liquid fertiliser, leaf mould and compost activator.
It should not be harvested in its first season as it needs to become established. The flowering stems should be removed in its first year as it will weaken the plants.Comfrey should also be regularly watered until well established.Bees, ants, ladybirds and scarlet tiger moth caterpillar love it.
Health Benefits and therapeutic uses of comfrey:
Comfrey offers therapeutic benefits but is has to be taken carefully as it can intoxicate the liver.In the past is was taken for bronchial problems, gastric and varicose ulcers for bone and teeth building properties in children, and for treating many female disorders.
Constituents of comfrey include mucilage, steroidal saponins, tannins, pyrrolizidine alkaloids, inulin, and proteins. But it also contains hepatotoxic pyrrolizidine alkaloids (PAs). (….. there are also non-hepatotoxic pyrrolizidine alkaloids.) Because of these PAs, the internal use of Comfrey can lead to veno-occlusive disease (VOD). VOD can in turn lead to liver failure.Comfrey, taken in extreme amounts, has been implicated in at least one death.
So best is external use only!!!
