What's the fastest way to get rid of a cold?

Time/supplements: There are a couple supplements that may help colds resolve faster, one is the chinese herbal supplement Yin Chiao (many brands), the other is Respigard (Nature's Nurse), a tonic made from red mangrove from Fiji. Both of these must be taken at the first sign of a cold to be effective. Once a cold is in full force you just have to wait it out.

Self-care: Rest, avoid physical exertion, drink plenty of fluids (2 liters per day). Cold medicines such as nyquill and Dayquil may help with the symptoms but will not make it go away faster.
