Comfrey is one of those medical plants that has been used for centuries, but still is fairly low key in the modern naturalistic herbal scene. This plant can grow to be 5 or 6 feet tall and almost as wide. It likes partial sun so will be in amongst a wooded edge or under a fairly open canopy. Some varieties like full sun, but do not get as large.
Boiled and pressed, the liquid of the leaf can be mixed into hand cream or used with aloe juice to soothe light burns. The Leaves themselves can be part of wrappings over poultices on wounds, rashes and burns. The fuzzy nature of the leaves can help 'worry' out small splinters .
The flowers can be used in salads. I wouldn't use the leaves as they are fuzzy. Add a few to the top of a salad for garnish and color. A light oil and vinegar dressing will really bring out the flavor.
Tea can be made out of the comfrey Root. Dig it up towards the end of summer, separate out the roots, replant one or two and keep the rest. Some people say to dry the root, some people say to roast or bake it. I have even been told by someone that if you pound it flat and then dry it, it is easy to cut into pieces later. I am not sure about any of it, but I have found the taste of the roasted comfrey is better for my palate. Comfrey root is a diuretic and is good if you are having weight gain because of water.
