There was a recent article stating that over-the-counter cough medicines may not be as effective as we think. Here is a link:
MSNBC article
I think that the article makes a good point, which must as always be taken in context. They are summarizing results of studies. These studies are always mixed in quality of design. All you can say is that studies don’t show overwhelming effectiveness for these cough meds.
The very important point is made that suppressing a cough can delay the seeking of treatment for more serious conditions. If a cough persists, you have trouble breathing, or see blood, you should see a doctor for further checkup.
Generally, you have two kinds of coughs- productive and non-productive.
The non-productive type is usually spastic, ie, you’re not getting anything up, the passages are just irritated.
A productive cough should never be suppressed. It is occuring for a reason. Get it up and out!
Sugary cough drops coat the throat and relieve irritation, but feed bacteria and can extend a cold. Zinc lozenges partially use this sugar coating relief and good ones actually get zinc into your throat tissue which has been shown to reduce duration of sore throats. Zinc does not reduce coughs. Zicam does the same thing (get zinc to mucous membranes) just gets it into your nose. Beware, though, this nasal form of zinc has been associated with loss of smell- it should not be used for long periods of time. Super cheap zinc lozenges are low in zinc, have a lot of sugar, and usually have a type of zinc which doesn’t dissociate in the throat. You should look for at least 23 mg of zinc *gluconate* and not another type.
The tireless advocate:
-There are herbs which will calm a spastic cough.
-There are expectorant herbs which will get the mucus out of your lungs so that the cough resolves sooner.
-There are herbs which stimulate immune function so that your cold is shorter and less severe.
-There are demulcent herbs (such as slippery elm) which coat mucous membranes without the sugar to feed bacteria.
-There are herbs which open the bronchioles (such as eucalyptus) to help mucus to break up.
-N-acetyl cysteine and various iodine preparations increase mucus breakdown.
I have a great cold/flu protocol which includes a eucalyptus steam inhallation, hot pack over the lungs, advice and supplements. Call for more info.
