Put Mastic to Work for
Halitosis May Be Linked to Dyspepsia
Killer breath is likely to disappear, however, when mastic
kills H. pylori
By Aaron W. Jensen, Ph.D.
Bad breath is better than no breath at all.
hat quotation is hard to argue with, but it doesn’t mean
that you have to accept bad breath (halitosis) and go on your merry way.
What’s the alternative? Well, for starters, you can be proactive and fight
halitosis by practicing good oral hygiene. Besides providing you with a blinding
smile and healthy gums, this is the best way to freshen your breath, because it
reduces bacterial growth in your mouth.
In many ways, your mouth is a perfect haven for all sorts
of bacteria. It’s warm, it’s moist, and best of all, it’s well nourished
by a steady stream of nutrients (carbohydrates, fats, and proteins) that you
thoughtfully provide by eating and drinking. As a result, there are far more
bacteria in your mouth (and nose) than you probably care to think about.
What’s worse, they can reproduce at a prodigious rate: under optimal
conditions, bacteria can divide about every 20 minutes, which means that a
single bacterium could generate a colony of over 16 million descendants in just
As the army of bacteria in your mouth goes about its
business of multiplying and dying, it can generate foul-smelling waste products,
such as hydrogen sulfide and methyl mercaptan, which are metabolic byproducts of
the sulfur-containing amino acids methionine and cysteine. Another disgusting
compound, with an odor vividly suggested by its name, cadaverine, comes from the
breakdown of a different amino acid, lysine.
Threefold Oral Hygiene with Mastic
How do you stop these nasty molecules from giving you
breath that could drop King Kong at ten paces? Simple—get rid of the bacteria
that produce them. That’s not easy, though, because every time you put
something in your mouth, you repopulate it with a host of bacterial pioneers
that want to set up camp.
Frequent mouth rinsing, brushing, and gum chewing are
effective against halitosis in most people. All sugarless chewing gums work
well, but one made from mastic—a natural gum resin derived from the mastic
tree—may be a particularly good choice for improving your breath, because it
also has antibacterial properties, as we will see below. Mastic gum is even
cited in the Talmud, which recommends it as a remedy for bad breath (see the
sidebar on this topic). Mastic can also be obtained in the form of mouthwash and
toothpaste, rounding out the three methods of breath control mentioned above.
The Talmud Teaches–About Halitosis, Yet
The Talmud, a collection of ancient rabbinical writings
that provide the basic underpinnings for the Jewish faith, has an interesting
take on halitosis: it states that bad breath is sufficient grounds for divorce!
In a recent paper that examines the Talmudic teachings on this subject, dental
researchers from Tel
summarize the relationship between marriage and bad breath. “In the
Talmud,” they write, “bad breath is considered a serious disability,
particularly regarding spouses and priests. The Talmud considers bad breath to
be a major ground for divorce, and prohibits priests with bad breath from
carrying out holy duties.” Wow, they don’t mess around.
Before the divorce is granted, however, why not try one of
the remedies, including mastic gum, recommended in the Talmud itself: “It is
forbidden to chew mastic on Sabbath, yet it is permitted for the prevention of
oral malodor.” How’s that for an endorsement?
It should be noted that in the time of the Talmud, the
inability to treat effectively many of the conditions that could lead to bad
breath, such as the advanced stages of gingivitis, periodontal disease, oral
ulcers, and diabetes, may have severely pushed the limits of marital intimacy,
even among the most romantic couples. One can’t help but wonder how many
marriages might have been saved during those times by a good toothbrush, some
zesty toothpaste, a bit of sparkling mouthwash, and a snappy breath mint. Mastic

H. pylori Is Nothing but Trouble for Your Stomach
Many kinds of bacteria populate your mouth. Some are
innocuous, while others, such as Helicobacter pylori, have a more sinister side
and can give rise to ailments far more serious than halitosis. H. pylori can
flourish in your mouth, but oddly, it is also perfectly at home in the
corrosively acidic environment of your stomach. It has an ingenious mechanism of
secreting a buffer layer of ammonia to counteract the stomach acid, which kills
most other kinds of bacteria. While thus protected from the body’s natural
defenses, H. pylori burrows through the stomach’s mucosal lining and takes up
more or less permanent residence—unless you do something about it—in the
underlying cell layer, where it can eventually cause ulcers to form.
H. pylori is, in fact, the primary cause of ulcers—both
gastric (stomach) and duodenal, which collectively are called peptic ulcers. It
is also the most frequent cause of gastritis (inflammation of the stomach
lining), and it may be a contributing factor in other gastrointestinal
disorders, including indigestion, heartburn, and dyspepsia. (See the sidebar
“H. pylori Hates Your Guts.”)
H. pylori Hates Your Guts
The Centers for Disease Control and Prevention (CDC)
estimates that 90% of all duodenal ulcers and 80% of all gastric ulcers are
linked to H. pylori infection. This evil little bug also increases the risk of
gastritis and slows recovery from the symptoms of gastroesophageal reflux
disease (GERD). Furthermore, H. pylori infection increases the risk of stomach
cancer 2-to-6-fold. Those are solid reasons for wanting to be pylori-free.
But are you home free once you rid yourself of H. pylori?
Maybe, maybe not. Because about half the world’s population is believed to be
infected with this bacterium, and because it can be spread by human contact,
chances of reinfection are high. Add to that the fact that food (particularly
meat) and many communal water sources are often contaminated with H. pylori, and
you really have to be on your guard. Once you’re reinfected, it’s back to
square one. You’ve been there and done that, and you don’t want to have to
do it again.
Here’s where good oral hygiene comes in. Anything you do
to reduce the growth of bacteria in your mouth decreases the risk that H. pylori
will recolonize your mouth and then, almost inevitably, your gut. Chewing gum
seems to be especially effective, because the mechanical removal of debris and
leftover sugars removes the vital nutrients that bacteria thrive on. So the next
time you pop that gum in your mouth (sugar-free, of course, and preferably
mastic), remember that you’re doing your breath and your gut a good turn.
Dyspepsia, by the way, is a pain or discomfort in the upper
abdomen or chest that’s often described in terms of gnawing or burning, often
with a sensation of fullness (having gas). It has many causes, notably peptic
ulcers and gastritis, but it can also be caused by several other conditions,
including stomach cancer, acid reflux, lactose intolerance, irritable bowel
syndrome, gallbladder inflammation, and even anxiety or depression.
Halitosis Comes from the Mouth (Duh)
But how are stomach ailments related to bad breath, you
ask? It’s a good question, because medical and dental experts say that the
overwhelming majority of cases of halitosis originate in the mouth, with most of
the rest coming from the nasal passages. In relatively rare cases, halitosis can
originate elsewhere in the body as a result of certain diseases, such as liver
failure, kidney failure, respiratory tract infections, lung abscesses, and
severe, uncontrolled diabetes. It almost never comes directly from the stomach
except during belching or, sometimes, with acid reflux, because ordinarily the
stomach is hermetically sealed. For that we can be most grateful, considering
the foul-smelling chemical processes going on in there.*
H. pylori Eradicated in Patients with Nonulcer Dyspepsia
It comes as a surprise, therefore, that a group of
researchers in Turkey claim that halitosis may be linked with the presence of H.
pylori in patients who have a common stomach condition called nonulcer dyspepsia
(i.e., dyspepsia that is not caused by an ulcer). There is a higher rate of H.
pylori infection in people with nonulcer dyspepsia (NUD) than in those without
it, but H. pylori is also extremely common in people who have no
gastrointestinal symptoms at all, as well as in people who do not have
But because other researchers had suggested that H. pylori
might be linked with halitosis, the Turkish group set out to determine whether
eradication of H. pylori would affect the occurrence of this condition in
patients with NUD. They followed the progress of 148 men and women (aged
20–70, average 38) who tested positive for H. pylori and were then treated for
it, using a regimen called triple therapy. This entails a twice-daily
administration of three different drugs for 14 days. Typically, two of the drugs
are antibiotics, and the third is a proton pump inhibitor, used to reduce acid
levels in the stomach. When the patients were again evaluated 4–6 weeks after
this therapy, it was found that eradication of H. pylori had been successful in
109 of them (74%).
Of the 109 patients in whom
H. pylori had been eradicated,
only 3 (2.8%) still suffered from
halitosis—a nearly complete
wipeout of the
Regardless of whether or not H. pylori had been eradicated,
almost all the patient symptoms recorded by the researchers were dramatically
reduced (the one exception was heartburn). They included bloating, diurnal and
nocturnal pain, nausea, and . . . halitosis, which dropped from 62% before
treatment to 13% afterward. The most dramatic improvement, however, occurred in
patients in whom H. pylori had been eradicated. Of the 109 patients in this
category, only 3 (2.8%) still suffered from halitosis—a nearly complete
wipeout of the condition.
Halitosis May Be Linked with H. pylori
Although this research is intriguing, it’s not clear that
halitosis was actually a symptom of NUD in the first place, or that it was a
symptom of H. pylori infection independent of NUD. Nor is it clear that
eliminating H. pylori was responsible for nearly eliminating the patients’
halitosis. Triple therapy, after all, kills many other kinds of bacteria besides
H. pylori. It must be noted, too, that the patients’ breath was not evaluated
for halitosis by chemical analysis, but rather by the testimony of relatives—a
highly subjective and unreliable method at best. Furthermore, the study was not
placebo-controlled, making a bad situation that much worse in terms of the data
having any real meaning.
Nonetheless, from various lines of reasoning, the authors
concluded that halitosis may be a symptom of H. pylori infection rather than of
NUD, even though they also cited evidence that there is apparently no link
between oral H. pylori infection and halitosis. Based on their results, they
suggested that, for patients with NUD, the presence of halitosis may be a
justification for undergoing eradication therapy.
Mastic Kills H. pylori
Triple therapy is an effective but aggressive (and
expensive) way to get rid of H. pylori, and each of the drugs has undesirable
side effects (see Mastic: No-Compromise Ulcer Eradication in Life
Enhancement, October 2000). If this approach gives you pause, you might want to
try a safe, natural, economical alternative, namely, mastic. Mastic is the gum
resin from a small evergreen tree (Pistacia lentiscus) that grows almost
exclusively on the small Greek island
Aegean Sea. It has been used for millennia to calm digestive ills as well as a variety of
other ailments (see Mastic Is More Than an Antibacterial in Life
Enhancement, December 2002).
Only in the last few years, however, have we begun to
understand how mastic works to aid the digestive system and improve breath. We
now know that it packs a potent antibacterial punch that enables it to kill H.
pylori. In addition, mastic attacks and kills a variety of other unwanted
bacteria, notably Escherichia coli and Staphylococcus aureus.
Thank You, Mother Nature
Nature has an arsenal of other agents besides mastic that
destroy bacteria. Some of these bacterial annihilators come in innocent guises,
such as those of St. John’s
wort, thyme, and cinnamon. St. John’s
wort contains hyperforin, a particularly resourceful compound that can destroy
bacteria that have become resistant to conventional antibiotics. Thyme and
cinnamon have the specific ability to inhibit the growth of H. pylori.
If you—or, more likely, those around you—are bothered
by halitosis, you owe it to them to do something about it, whether it has
anything to do with H. pylori or not. You owe it to yourself, however, to ensure
that your gastrointestinal tract is as healthy as possible. That means ridding
it of H. pylori, because of its known connections with gastritis and ulcers,
which can lead to stomach cancer. Since Mother Nature has been so kind as to
provide mastic for this purpose, it would be nice to give her a thank-you kiss
on the cheek. But first, make sure your breath is fresh!
