The new, separate eschar at the top at first appeared to be attached by one thick root. Then, towards the end, several tiny filament-like roots almost as fine as human hairs were attached to the scab. It appears as though a root mass gives rise to the scab, and then thins down into several delineated "leaders." At that stage it is near detachment, and did so a couple of hours after the exceptionally fine stranded roots were observed. The photo was taken July 4th.
The subject will wait a while and in a few weeks re-apply the bloodroot salve and see if there is a reaction. This was an unusual case in that far too much manipulation was done for photographic purposes, large roots were broken off and even left hanging out of the tissue, making careful re-evaluation of the site by black salve application later on a necessity.
