What is the rapid treatment for common colds?

Listerine: Vitamin C is indeed helpful at doses of 1000-2000 mg daily. A study done 20 yrs ago also showed that Listerine gargles every 4 hours for the first 3 days of a cold sh0ortened a cold by 1.5 days. None of the other mouthwashes nor salt water gargles had any effect.
