Colds are a virus. A cold gets in your nose and your sinuses and starts to duplicate there, producing a lot of mucus. Many will experience postnasal drip – mucus dripping down the back of the sinuses into the throat – when they go to bed. The mucus contains a virus or bacteria. When it reaches the back of the throat, it causes swelling and inflammation and can even spread into the ears.
Taking one tablespoon of silver sol three times a day, and spraying intranasally four or five times a day, will help reduce congestions and inflammation. Mouth rinse, eardrops, eye drops, nose drops, and throat spray can all be used as well.
