Common cold treatments – what works, what is just plain nonsense

common cold treatments

It’s that time of year when dozens of common cold treatments are all over the place. On TV advertisements. On displays in your pharmacy. Once again, it’s time to take a look at these lotions and potions to determine which work and which are complete pseudoscientific nonsense.

There are literally a dozen or more homeopathic, herbal, and other unproven concoctions to prevent or treat the common cold, caused by rhinovirus. These common cold treatments are a significant part of the estimated global US$278 billion supplement and nutraceutical industry.

So, positive results, if they exist, should be treated with a high degree of skepticism. Continue reading “Common cold treatments – what works, what is just plain nonsense”

cold-cureIt’s getting colder outside, and if you go into any pharmacy, grocery store, chemist, or superstore, you will find literally a dozen or more homeopathic, herbal, or other unproven lotions and potions to prevent or treat the common cold, or rhinovirus. These supplements are a significant part of the annual US$108 billion dollar supplement/nutraceutical industry. 

These alternative medicine (so named because there is no scientific evidence supporting their efficacy, let alone safety) products make claims that are so wonderful, many people take them. Then they themselves tell their friends how fast they got rid of their cold. Or that their cold wasn’t as bad after taking the supplement.

The problem is that determine the length and severity of the course of the common cold is entirely subjective. Since the disease is rather mild with few serious complications, it’s hard to determine when it exactly stopped and started, and how bad it was.  The common cold tends to resolve itself without external help, but there really isn’t much you can do to make your immune system attack that cold faster.
