If you've ever taken medicated syrup or drops for an irritating cough and
then waited, and waited, only to find that the cough resolved on its own time, this
article is for you. Yes, that means virtually everyone. Guidelines published in
January by the American College of Chest Physicians (ACCP) state that over-the-counter
cough medications are ineffective in treating the underlying causes of
cough.1
"With over-the-counter cough medicines under
fire, the message seems clear: It's time to
consider natural alternatives."
According to Dr. Richard Irwin, chair of the ACCP cough guidelines committee,
over-the-counter cough syrups generally do not contain enough medicine to be effective,
or they contain drugs that have not been proven to be effective for treating the
common cough.2 "In most cases, a cough that is unrelated to chronic lung conditions,
environmental influences, or other specific factors will resolve on its
own."3
The ACCP guidelines address cough in both the adult and pediatric populations.
In fact, they strongly recommend against the use of over-the-counter cough and
cold medications by children ages 14 and younger. "Cough is very common in children.
However, cough and cold medications are not useful in children and can actually be
harmful," said Dr. Irwin.
"An October 2005 study suggests North American
ginseng extract can be a safe and effective natural remedy
for treating colds and cold-related symptoms,
including cough."
Adding to the evidence against cough medicines, a recent review in
Respiratory Phyisology & Neurobiology attributes the perceived
"benefit" of cough medicines to nothing more than the placebo
effect.4 The review authors also speculate that it
may not be coincidental that most cough medicines are formulated as sweet syrups,
rather than as tablets or capsules. In other words, people may take them because they
taste good, not because they help get rid of their coughs.
But wait, there's more: While cough expectorants and suppressants have little or
no effectiveness in treating cough, they are potentially effective in causing
cavities, suggests a report published in the January/February issue of
General Dentistry,5 the peer-reviewed journal of the American Academy of General Dentistry. The report
revealed that many syrupy medications, including those commonly used for
combating cough, are characterized by low pH levels, high acidity and sugar, which can
cause erosion to the outer layers of the teeth. The report also noted that medicine
administered before bedtime, when the flow of saliva decreases, can increase dental
damage.
All of the above adds up to a fair amount of depressing news about cough
medicine, and it comes straight from the allopathic community. The bottom line: Medical
manage ment of cough doesn't seem to be all that effective, and might carry health
risks. What can you do? Let's take a minute and consider some simple natural methods
of treating'that bothersome cough:
- An October 2005 study suggests that North American ginseng extract can be a
safe and effective natural remedy for treating colds and cold-related symptoms,
including cough. According to the researchers, ginseng "appears to be an attractive natural prophylactic treatment for upper respiratory tract
infections."6
- Zinc may relieve cough and other cold symptoms, according to a study
published in the Annals of Internal
Medicine.7 Subjects recruited within 24 hours
of developing symptoms of the common cold were administered a single zinc
lozenge (12.8 mg zinc acetate) or placebo every two to three hours while symptoms
were present. Duration of cough in the zinc group was 3.1 days per person compared
with 6.3 days in the placebo group.
"According to a recent study in the Annals of
Internal Medicine, subjects given zinc lozenges suffered
from cough for just over three days, compared with more
than six days for those taking placebo."
- Dr. Edward Schulman, an American Thoracic Society representative on the ACCP
cough guidelines committee (the ATS endorsed the guidelines), recommends drinking
plenty of fluids and eating chicken soup to help get rid of the common cough. According
to Schulman, cold-related coughs generally last less than three
weeks.2
- Andrea Candee, author of Gentle Healing for Baby and Child A
Parent's Guide, says the anti-inflammatory properties of onion and honey can help
relax coughing spasms and soothe irritated tissue. Both are antimicrobial as
well.8 Thyme also can be combined with honey to make a natural cough syrup, says Candee.
Thyme has antimicrobial properties and is a natural
expectorant.8
Other nonpharmaceutical options are out there some with research to back
them; others whose merits are based on clinical observation and/or sheer experience.
The point is that the majority of people have taken cough syrup and/or cough drops
at least once; how many have tried natural cough remedies? With the release of the
ACCP guidelines, the message seems clear: When it comes to treating the common cough,
it's time to think natural.
