Arnica is wonderful for bumpa and bruises. Calendula works better for
 scratches, scapes, abrasion, burns, thrush and shallow cuts. Graphites is
the remedy for crevices, cracks and fissures. Do not use calendula on cracks,
punctures or fissures because it closes the uppermost layer of the skin
without allowing the deeper inner area heal first. Ledum is for puncture like
wounds.
