The reason is that the organism that originally needed Graphites was affected globally in its peripheral areas, where apart from the skin eruptions, we see distortions of the nails, fissures in the anus, discharges from the canthi, fissures of canthi, conjunctivitis, keratitis, eruptions on lids, cracks and discharges behind the ears.
The general impression that you will get from a Graphites case is that the eruptions and discharges are all over the body, especially around the hair of the head, behind the ears, in the eyelids, around the mouth, in the crook of the elbow, behind the knee, in the nails and around them, and in the back of the hands. These are the areas primarily affected at the peripheral level.
An interesting feature in Graphites is its photophobia; so severe that is painful. Another usual ailment is the tendency of the organism to form keloids in the skin after ulcers or boils have subsided and also internal keloids, or benign excrecences, in areas of surgical intervention.
If there are no skin eruptions to point to this remedy, you can almost be sure that the patient had an eruption many years ago that was suppressed. Then the triple symptomatology of keloids, constipation and conjunctivitis with photophobia points only one way: to Graphites.
The Graphites patient has a basically strong organism in spite of the extreme suffering, that is why it is certain that the remedy that is given after the suppressed eruption was most probably originally indicated as much as twenty years ago. So after the reappearance of the original eruption, the same remedy should be continued in treating the eruption, it is a fact that strong organisms maintain the same remedy all their life, and a lot of Graphites cases belong to this group.
