Is it possible to beat a head cold using home remedies no over-the-counter medications?

Common cold. yes. And no. You can certainly use many home remedies to make yourself more comfortable while the cold runs its course. Getting plenty of rest is also extremely important so the body can heal itself. However, neither home nor current prescription remedies will actually get rid of the common cold. There is an old saying that a cold lasts 7 days if you treat it, but only a week if you don't.
Cold Symptoms. Yes, since nothing really works anyway. Use anything that you feel makes you feel better as long as it is not dangerous or illegal.
