Firstly there's no lifelong cure for the common cold. Antibiotics are only effective against infections of throat and are of no use against cold viruses. Over-the-counter (otc) cold preparations won't cure a common cold or make it go away any sooner, and most have side effects. A saltwater gargle 1 teaspoon salt and 1/2tsp turmeric dissolved in a glass of warm water can temporarily relieve a sore or scratchy throat. To help relieve nasal congestion
, try saline (pure salt water) nasal drops. If you have a throat infection
, or a viral cold then do reply back for medications. Being also a general physician
, I prescribe both evidence based herbal as well as allopathic medicines complementing with dietary tips taking into account patient preferences.
