There's a cure for the common cold.

Nobel Prize winner Linus Pauling, in his last interview months before his death continued to advocate high doses (so called “megadoses”) of vitamin C to cure and prevent colds. The basic principle of his idea that vitamin C in these doses could cure cold, was that man was one of the few animals that does not produce its own vitamin C. He expresses it as some kind of a design flaw in our genetic make-up. He calculated that an average adult should need about 10-12 grams of vitamin C daily.

High doses of vitamin C at the beginning of a cold have shown in some cases to reduce the severity of the symptoms to a modest degree, due to a mild antihistaminic effect. Vitamin C has not yet been proven to prevent or cure the common cold.

Vitamin C is an important part of a healthy diet. It is not a miracle drug, and may cause harm if taken in extreme excess. However, if you wish to supercharge yourself with vitamin C to see if it works, do not feel frightened. The only harm that vitamin C can do is cause diarrhea, and that only after taken extreme amounts, which is virtually impossible by natural means such as eating citrus fruits or drinking orange juice.
