In none of the Homoeopathic treatises that I possess do I find any mention of the above remedy. I am surprised at this, for I believe it to be a very valuable one in certain cases. Its common name of _knitbone_ seems to point to popular experience of one of its uses; but I believe its knitting, or uniting, power extends to muscular and other tissues of the body, as well as to the bones. Let me give two instances of my own personal experience. Many years ago I had an inguinal rupture on each side, not extensive ones, but causing a protrusion about the size of half a small walnut. After wearing a truss for some time, I bethought me of what I had heard of the uniting power of Comfrey, and made some tincture from the root, and rubbed it in. After doing so two or three times, the signs of rupture quite disappeared, and the parts remained sound for about three years; when, from some cause or other, the right side broke out again, but as it did not give much trouble I neglected it for some time, and then tried the Comfrey tincture again, but this time without success. I suppose the ruptured edges had got too far asunder. The left side, however, which originally was the worse of the two, has kept sound ever since. I think this shows that a rupture, if not too extensive, and if taken in time, may often be cured by this remedy. The other case I have to relate was of a different kind. Five weeks ago I had a fall on my back, the whole force of which was concentrated on a small portion of the lower spine, through the intervention of the back pad of my truss. I thought for the moment my back must have been broken, the pain was so excessive; and not only the back, but diaphragm and all the organs below it suffered acutely for three or four weeks after the fall. But a fortnight after the fall I was for the first time conscious of a pain and tenderness higher up the spine, at a point, I think, where ribs commence, and on feeling I found a protuberance there, as if a partial dislocation had taken place there. I again thought of Comfrey, and had some of the tincture applied. The tenderness at the point subsided after two or three applications, and in a few days the protuberance disappeared. * * * On more careful examination I find that the point of secondary disturbance was higher up than I have described--two or three inches higher than the first insertion of the ribs in the spinal column.
