Under what policies will my colonists use a Medkit, Salewa, or alternatives? I read the FAQ on how to make them carry the kits, but haven't seen them use it; they ignore everything when under "Industrial or Lower", and only go for Glittermedicine when Best is selected.

A second doubt is, I noticed the cost of making the Salewa Kits was immense compared to a single Vanilla Medicine, but it still only has a single treatment charge, with only a minor buff to max treatment effectiveness. Am I missing something about the pros and cons of it?
