Centuries after the apocalypse, this humanitarian group, called O.R.E, Orginization Rebuilding Earth,is running a hospital out in a place called Des ( Former Des Moines). They’ll help anyone who comes to their doors, and will except any volunteers.

They problem is, most medicine for the old days is long, long gone, and so is the ability to make new medications. The world is stuck back with 1680s technology, and so my question is, what could they do to make the materials needed listed below?

Antiseptics- They need some antiseptics to sterilize wounds and such.

Painkillers- It’s hard to place back on bones when the patient is screaming louder than a hyena. They need painkillers.

Stitches- They need a material that can be used to stitch up patients.
