BEHOLD!!!!
The only known "cure" for the common cold
That stuff can be potentially dangerous! I've seen reports of people that have used it only to feel a burning sensation in their nose resulting in a complete loss of the sense of smell. Plus it's impossible to "cure" a cold.
The best thing to do is practice preventative methods, but we all know that's not possible. I recently got a cold and checked out a few websites for remedies. They all stated that zinc, whether in lozenge (cold-eeze

) or tablet form, all help reduce duration of the said cold. I went and bought a jar of zinc tablets
(beware, they may make you nauseous) and took one while eating chicken noodle soup and drinking plenty of liquids. Seriously, not even two days later I had no signs or symptoms of the cold left. It's the fastest I've ever gotten over a cold.
Also, while I was doing that research, one site said that the over the counter cold medicines only make things worse in the long run. They mask the symptoms and after a few days of feeling good you get used to them and the symptoms surface only to be worse.
The list of things I found to help me were:
1. Chicken noodle soup. "First, it acts as an anti-inflammatory by inhibiting the movement of neutrophils — immune system cells that participate in the body's inflammatory response. Second, it temporarily speeds up the movement of mucus through the nose, helping relieve congestion and limiting the amount of time viruses are in contact with the nose lining." The article I'm quoting (link posted at the end of my post) suggests that homemade has the same benefits as canned/store bought soup. There aren't many canned soups that don't provide the benefits listed.
2. Plenty of sleep!
3. Plenty of liquids!
4. Zinc
