I haven't had the symptoms of a cold in ~5 years. Being a 'professional' sinus sufferer in Phoenix, I can spot the signs in the first few hours of a cold, as I'm attuned to the area. I start dropping zinc lozenges (have 'em at home, work and in the car) immediately, and the symptoms never appear. I can *tell* that I still have the cold 'cos my face feels odd, but none of the nasty drippy stuff. The weird face feelings go away after about 2 or 3 days, and nobody but me can tell I have a cold, nowadays. It's not a cure-all, but it works for me.
The best I can tell from researching it on the 'net is that it severely limits the early 'macrophage attack' part of the cold. Macrophages are kinda like a blind man with a shotgun. They blow away cells at random, hoping to hit a few that have the virus in 'em, releasing the viral fragments into the bloodstream so the t-cells can recognize, go hog wild reproducing, then mobilize and target the infected cells. All of the ugly symptoms from a cold are from the first stage of defense. The drippy nose & sore throat are from YOUR defense mechanisms trying to alert the rest of the immune system. They blow away so many good cells in the process that you get the drippy stuff from all of the damage to nose & throat linings. Yucchh.
From practical experimentation when I first tried the zinc, it's totally worthless if you wait a day after the earliest onset of symptoms. The quicker you start, the better. Also, it doesn't do any good after about the third day, so it's a good idea to quit and stop flooding your system with zinc. If you follow the directions, you're pretty well saturated after the first day, and you can *taste* it 24/7. It's foul, but better than the drips.
The manufacturer's webpage used to says it "supercharges your immune system", which is bubble-head nonsense. Your immune system is the PROBLEM, since it goes into overdrive with a cold. Many of the 'alternate' medical cures are described similarly by their proponents, which makes me distrust 'em. There's no excuse for fuzzy thinking. I don't try any cures that include magic rattles, unless there's solid proof that it helps.
BTW, I'm an engineer, not a virologist. I may have screwed up the names of the macrophages and t-cells, or got 'em confused with other parts of the immune system, but the basic concept is right. I had to do a *lot* of research to find out how things really worked in lay terms.
The zinc I use is Cold-Eeze 'tropical fruit', 'cos it's a little less disgusting tasting than the other flavors & vendors.
