A cold is a virus and can�t be cured � you just have to let it run its course.
All you can do is try to relieve the symptoms to make it more bearable.
I�ve tried vitamin C, which seemed to help, but I can�t tell how effective it was for sure because I don�t know what would�ve happened if I hadn�t taken it. It can�t do any harm to take it in reasonable doses, though.
Orange juice is another thing I tried � very good if you�re feeling dehydrated.
I think a dash of whisky or brandy in your tea or coffee is beneficial! Makes you feel better for a while.
