Also, doesn't salt kill live plants?
Not so much in the amounts of treating an injured/sick fish.
They will stop growing near as much, and if exposed to salt for a lengthy amount of time, they might either discoler, or lose some of their more prominent bushiness.
A simple treatment of a couple days or a week or two of salt will have very little negative effects on the plants.
