> She had to get a prescription for the saline.

Probably due to people previously being able to buy saline over the counter, and using it to inject themselves with etc. Misuse of things by people generally ends up with knee-jerk responses by regulators.

Isn't saline literally just salt water?

Yes, it's just very clean water with 0.9% of salt.

This is saline that you're going to warm up and then inhale. And you're only going to do this if you're already ill.

I don't think you should need a prescription for saline, but it's a little more complicated than salt water.
