Masking the symptoms, as you refer to it, still has value of course. If you can push away a headache or get rid of congestion or chronic leakage/coughing/etc. then you can be more productive or sleep which is when your immune system gets very effective.

It's just, I thought most people knew that the point wasn't about curing symptoms, just suppressing them so you don't have to suffer quite as badly while your immune system does what it is supposed to.
