3. Gargling with mouthwash
Gargling with mouthwash as a treatment for a cold really doesn’t sound very effective. Doctors often say that the best thing you can do is get plenty of rest. When you have a sore throat, it’s inflamed in the first place and mouthwash will irritate it even more. Drink lots of warm liquids and get lots of rest. There’s nothing else you can do.
4. Colloidal silver
Colloidal silver is a suspension, in which tiny silver particles are distributed in a cream. A few years back there was a massive campaign about its magical curing properties. Since then specialists have warned many times that colloidal silver is not just ineffective in treating most illnesses, but it’s actually dangerous. It can build up in your system over time and long-term use might leave you intoxicated or with a bluish skin discoloration, making you look like a Smurf.
