Does salt water cure common cold?

There is no scientific evidence that salt water cures the common cold. The common cold is a viral infection of the nose and throat caused by more than 100 different viruses. There is no cure for the common cold, but symptoms can be relieved with over-the-counter medications such as pain relievers, nasal decongestants, and antihistamines. Salt water can help to relieve the symptoms of a sore throat, but it will not cure the underlying viral infection.
