Agree that normal saline, 0.9% NaCl is isotonic and should not dry tissues is used in moderation.
When trying to thwart a cold/sore throat, I like to gargle with a supersaturated NaCl solution. I do not normally use nasal spray/saline or a netti pot. I’m a little skeered about amoeba.

And for the love of God do NOT use Morton salt in any shape form or fashion.
Making an isotonic saline solution is a precise, but simple, science. The prefix “iso” refers to something that is equal and means that the concentration of saline — or the amount of salt — is roughly equal to the salt concentration in body fluids. This amount is about 0.9 percent or 9g per 1000ml of fluid. It is about 1/4 tsp. of salt per 8 oz. of water. Using more salt makes a hypertonic solution, and using less salt makes a hypotonic solution.
