Here is the bad news. It is scarcely an exaggeration to assert the following.

Nothing is known that alters the time course of a cold. There is nothing that you can buy that will suppress a cough*. There is no such thing as a "demulcent" or an "expectorant" There is no such thing as a "tonic". It would be nice if these things existed, but they are figments of the imagination. Nonetheless they sell by the truckload and vast amounts of money are made by selling them.

[*morphine may have a modest effect, but you can't buy it]
