Pellitol contained zinc oxide, calamine, bismuth subgalate, bismuth subnitrate, resorcinol, echinacea fluid extract, and juniper tar. These ingredients are both disinfecting and adhesive, so that as the ointment gradually dried and shrank (a process lasting several days), it healed ulcers, dried pus and debris, and reduced bacterial growth.
This ointment contains zinc oxide, calamine, bismuth subnitrate, resorcinol, juniper tar, and bismuth subgallate, which are (except for echinacea) the same ingredients as Pellitol in a slightly different formula.
