I have to go with option 1, but I believe that there should be more herbal options, perhaps berries or leaves from certain plants in certain areas properly prepared will give SOME healing. It would either be learnable by scholars or perhaps Barbarians from the climes maybe even some experianced Borders might know that a specific plant would help. Depending on the plant perhaps double normal healing or a plus to a saving throw vs poison or infection. it sould have a realiistic flavor and in general be Conanesque. Another option would be to have either the kitian or Vendeyian mystics know vertain spells that would permote healing though perhaps with a limiter and may provide the service at a heafty price. I would consider that option since in several tales it states that the Kitians are the formost sorceers in the world.
