I beg to differ and take it from me who's had a long career working in healthcare. When you get hit with a cold, a cheeky whisky snifter can work wonders. The odd splash in a cup of black coffee can work wonders. Taking into account current medications and clinical history of course.
Oh and
@ringwood , for throat infections sipping warm drinks during the course of the day can help. Boiling up some ginger, adding some lemon and as long as you're not diabetic a splash of honey can do the job. In fact that is just as effective if not better than most preps you can buy OTC from your local pharmacies.
