You can increase the disease fighting power of your body by herbs and spices. Some of them are commonly available.
Garlic from whfoods, is not just good for fighting vampires ("aswang in the PHL) but in combatting colds and flu. Garlic has allicin which is good vs. cold and flu. Garlic is anti fungal, anti bacterial and anti inflammatory
Garlic helps reduce blood pressure and is effective vs. cancers of: brain, lung and prostate. Garlic is a blood thinner. Garlic though can affect your breath and can cause stomach irritation
There are other things that undermine your health and immunity:
1. lack of sleep and rest;
2. lack of Vitamin D,
3. stress
4. personal hygiene like simple things as washing of hands
Taking garlic is cheaper than taking the $100 Tamiflu which can cause allergy and even suicidal tendency

If you want a simple way to increase the disease-fighting power of
your meals, be generous with your use of high-quality herbs and spices.
This applies year-round, but as cold and flu season nears, you may want
to consider spicing things up more than you might normally.
There is no shortage of research showing that herbs and spices are
among the healthiest you can consume. And they’re a “secret weapon” that
just about everyone can take advantage of, regardless of your budget.
Garlic in particular has long been hailed for its healing powers, especially against infectious diseases like cold and flu.
This is likely due to its immune boosting effects. Fresh garlic is
also a potent antibacterial, antiviral and anti-fungal agent. But its
therapeutic effects may go much further than that.
Garlic—An All-Around Health Boosting Herb
The featured article in Medical News Today1
contains an impressive list of garlic’s historical use as a natural
medicine, and modern research to back up the wisdom of such antiquated
claims. Green Med Info has also assembled a list of studies
demonstrating more than 150 beneficial health effects of garlic! For
example, studies show that regular consumption of (primarily raw)
garlic:
- May be effective against drug-resistant bacteria
- Reduces risk for heart disease,2 including heart attack3 and stroke
- Helps normalize your cholesterol4 and blood pressure
- Protects against cancer,5, 6 including brain,7 lung,8 and prostate9 cancer
- Reduces risk of osteoarthritis10
It’s thought that much of garlic’s therapeutic effect comes from its
sulfur-containing compounds, such as allicin, which are also what give
it its characteristic smell. Other health-promoting compounds include
oligosaccharides, arginine-rich proteins, selenium and flavonoids.11
Research12
has revealed that as allicin digests in your body, it produces sulfenic
acid, a compound that reacts with dangerous free radicals faster than
any other known compound.
This is one of the reasons why I named garlic as one of the top seven anti-aging foods you can consume. Garlic is also a triple threat against infections, offering antibacterial, antiviral and antifungal properties.
Not only is it effective at killing antibiotic-resistant bacteria,
including MRSA, but it also fights yeast infections, viruses and
parasites. Garlic must be fresh to give you optimal health benefits
though.
The fresh clove must be crushed or chopped in order to stimulate the
release of an enzyme called alliinase, which in turn catalyzes the
formation of allicin.13
Allicin in turn rapidly breaks down to form a number of different
organosulfur compounds. So to “activate” garlic’s medicinal properties,
compress a fresh clove with a spoon prior to swallowing it, or put it
through your juicer to add to your vegetable juice.
A single medium size clove or two is usually sufficient, and is
well-tolerated by most people. The active ingredient, allicin, is
destroyed within one hour of smashing the garlic, so garlic pills are
virtually worthless.
You also won’t reap all the health benefits garlic has to offer if
you use jarred, powdered or dried versions. Worse yet, at least two
supermarket-brands containing garlic powder imported from China have
been found to be contaminated with high levels of lead, arsenic and
added sulfites, according to a recent article by PreventDisease.com.14
If you develop a socially offensive odor, just decrease the amount of
garlic you’re consuming until there is no odor present. If garlic makes
you feel ill, this is probably your body's way of letting you know you
should avoid it.
Garlic versus Tamiflu
Garlic may be particularly useful in preparation for cold and flu
season, as it contains compounds capable of killing a wide variety of
organisms, including viruses and bacteria that can cause earaches, colds
and influenza. The respected research organization Cochrane Database—which has repeatedly reported that the science does not support the use of flu vaccine as a first-line defense—has also reviewed studies on the alternatives, such as the use of garlic.15
They found that those who took garlic daily for three months had
fewer colds than those who took a placebo, and, when they did come down
with a cold, the duration of illness was shorter—an average of 4.5 days
compared to 5.5 days for the placebo group.
While this may not seem overly impressive, it’s still better than the results achieved by the much-advertised flu drug Tamiflu.
If taken within 48 hours of onset of illness, Tamiflu might reduce the
duration of flu symptoms by about a day to a day and a half. That's the
extent of what this $100-plus treatment will get you. It’s virtually identical to just taking garlic on a regular basis!
However, some patients with influenza are at increased risk for
secondary bacterial infections when on Tamiflu—a risk you won’t take by
eating garlic... Other adverse events
of Tamiflu include pediatric deaths, serious skin reactions, and
neuropsychiatric events, including suicide committed while delirious.
Cold and Flu—Symptoms of Vitamin D Deficiency
While colds and flus are caused by viral infections, compelling
research suggests that your ability to "catch" these infections may
actually be a symptom of an underlying vitamin D deficiency.
Vitamin D is a potent antimicrobial agent, producing 200 to 300
different antimicrobial peptides in your body that kill bacteria,
viruses and fungi. Suboptimal vitamin D levels will significantly impair
your immune response, thereby making you far more susceptible to contracting colds, influenza, and other respiratory infections.
In the largest and most nationally representative study16
of its kind to date, involving about 19,000 Americans, people with the
lowest vitamin D levels reported having significantly more recent colds
or cases of the flu -- and the risk was even greater for those with
chronic respiratory disorders like asthma. At least five additional studies also show an inverse association between lower respiratory tract infections and vitamin D levels.
The best source for vitamin D is direct sun exposure. While it may
not be possible to get enough sun exposure during the winter, every
effort should be made to attain vitamin D from UVB exposure as there are
many additional benefits from this route other than vitamin D. The next
best option to sunlight is the use of a safe indoor tanning device.
As a last resort, if neither natural nor artificial sunlight is an
option, you may taken an oral vitamin D3 supplement. However, if you do,
you need to be aware of the following:
- Make sure you’re taking the correct vitamin D supplement. You want D3, not D2, as the latter may end up doing more harm than good.
- Based on the latest research from GrassrootsHealth, the average
adult dose required to reach vitamin D levels of about 40 ng/ml is
around 8,000 IU's of vitamin D3 per day. For children, many experts
agree they need about 35 IU's of vitamin D per pound of body weight.
- Get your vitamin D serum level checked at regular intervals to
make sure you’re taking the appropriate dose to get within the
therapeutic range of 50-70 ng/ml.
- If you’re taking high dose vitamin D supplements you also need to take vitamin K2—not
K1 that is typically in vegetables as it will not work synergize with
vitamin D. Vitamin K2 deficiency is actually what produces the symptoms
of vitamin D toxicity, which includes inappropriate calcification that
can lead to hardening of your arteries. The reason for this is when you
take vitamin D, your body creates more vitamin K2-dependent proteins
that shuttle the calcium into the appropriate areas. Without vitamin K2,
those proteins remain inactivated, so the benefits of those proteins
remain unrealized.
Four Factors That Undermine Your Immune System
Again, it’s important to remember that both colds and various influenzas are caused by a wide variety of viruses, not bacteria. Hence, taking an antibiotic for your cold or flu will NOT do you any good whatsoever. Antibiotics only
work on bacterial infections, such as sinus, ear and lung infections,
including bronchitis and pneumonia. The latter two are potential
secondary infections that can develop from a serious bout of cold or
flu, so you do want to keep an eye out for signs and symptoms of such
bacterial infections.
At the end of this article, you’ll find some guidelines to help you decide when it would be prudent to see a doctor.
Now, the most common way cold and flu viruses are spread is via
hand-to-hand contact, so the easiest way to cut down your risk is to
frequently wash your hands (see next section below). However, the key to
remember is that being exposed to a cold virus does not mean that
you're destined to get sick. Again, whether or not you’ll actually get
sick is primarily dependent on the functioning of your immune system. If
your immune system is operating at its peak, it should actually be
quite easy for you to fend off the virus without ever getting sick.
As discussed above, vitamin D deficiency is a major factor that will
depress your immune function, leaving the door open to invading viruses.
Other lifestyle factors that can depress your immune system, alone or
in combination, include:
- Eating too much sugar/fructose and grains.
Sugar in all its forms takes a heavy toll on your immune system. One of
the ways it does this is by unbalancing your gut flora. Sugar is
"fertilizer" for pathogenic bacteria, yeast, and fungi that can set your
immune system up for an assault by a respiratory virus. Remember, 80
percent of your immune system lies in your gastrointestinal tract, which
is why limiting your sugar intake is CRUCIAL for optimizing your immune
system.
It would be wise to limit your total fructose consumption to
below 25 grams a day if you're in good health, or below 15 grams a day
if you have high blood pressure, diabetes, heart disease, or are insulin
resistant or are trying to recover from an acute illness like the flu.
- Lack of sleep. If you aren't getting enough
restorative sleep, you'll be at increased risk for a hostile viral
takeover. Your immune system is also the most effective when you're not
sleep-deprived, so the more rested you are the quicker you'll recover.
You can find 33 guidelines for a better night's sleep here.
- Insufficient exercise. Regular exercise is a
crucial strategy for increasing your resistance to illness. There is
evidence that regular, moderate exercise can reduce your risk for
respiratory illness by boosting your immune system. In fact, one study17
found that people who exercised regularly (five or more days a week)
cut their risk of having a cold by close to 50 percent. And, in the
event they did catch a cold, their symptoms were much less severe than
among those who did not exercise.
Exercise likely cuts your risk of colds so significantly because
it triggers a rise in immune system cells that can attack any potential
invaders. Each time you exercise you can benefit from this boost to your
immune system. It can also help boost your immune system acutely,
by increasing your body temperature. This helps kill off invading
pathogens, similarly to the fever your body produces when sick.
- Using ineffective strategies to address stress. Emotional
stressors can also predispose you to an infection while making cold
symptoms worse. Finding ways to manage daily stress as well as your
reactions to circumstances beyond your control will contribute to a
strong and resilient immune system. Effective strategies include a
variety of energy psychology tools, such as the Emotional Freedom Technique (EFT).
Other All-Natural Strategies That Send Pathogens Packin'
Frequently washing your hands
with soap and water is one of the easiest ways to wipe out germs and
viruses and reduce your chances of becoming sick. Don’t make the mistake
of using antibacterial cleansers,
as their widespread use contributes to strains of resistant bacteria,
or "superbugs" that render antibiotics useless. Besides, research18
has shown that people who use antibacterial soaps and cleansers often
develop a cough, runny nose, sore throat, fever, vomiting, diarrhea and
other symptoms just as often as people who use plain soap and water.
There’s no real justification for using an antibacterial soap when plain
soap is safer, and just as effective.
Another strategy that many report success with is to administer a few
drops of 3% hydrogen peroxide (H2O2) into your ear canal. Quite
frequently, people claim to have been able to cure a cold or flu within
12 to 14 hours this way. Simply put a few drops into your ear; wait
until the bubbling and stinging subside (usually 5 to 10 minutes), then
drain onto a tissue and repeat with the other ear.
There are also a number of supplements and simple treatments that can
be beneficial for colds and influenza, but I believe they should only
be used as adjuncts to an otherwise healthy diet and lifestyle. For
detailed instructions that will help set you the right path can be found
in my optimized nutrition and lifestyle plan. Some of the more helpful options for cold and flu—besides vitamin D and garlic discussed above--include:
Zinc: Research on zinc
has shown that when taken within one day of the first symptoms, zinc
can cut down the time you have a cold by about 24 hours. Zinc was also
found to greatly reduce the severity of symptoms. Suggested dosage: up
to 50 mg/day. Zinc was not recommended for anyone with an underlying health condition, like lowered immune function, asthma or chronic illness. |
Vitamin C:
A very potent antioxidant; use a natural form such as acerola, which
contains associated micronutrients. You can take several grams every
hour till you are better unless you start developing loose stools. |
Olive leaf extract:
Ancient Egyptians and Mediterranean cultures used it for a variety of
health-promoting uses and it is widely known as a natural, non-toxic
immune system builder. |
Propolis:
A bee resin and one of the most broad-spectrum antimicrobial compounds
in the world; propolis is also the richest source of caffeic acid and
apigenin, two very important compounds that aid in immune response. |
Oregano Oil:
The higher the carvacrol concentration, the more effective it is.
Carvacrol is the most active antimicrobial agent in oregano oil. |
Medicinal mushrooms, such as shiitake, reishi, and turkey tail. |
A tea made from a combination of elderflower, yarrow, boneset, linden, peppermint and ginger;
drink it hot and often for combating a cold or flu. It causes you to
sweat, which is helpful for eradicating a virus from your system. |
Echinacea
is one of the most widely used herbal medications in Europe to combat
colds and infections. One review of more than 700 studies found that
using Echinacea can reduce your risk of catching cold by as much as 58 percent. |
When Should You Call Your Physician?
Generally speaking, if you have a cold, medical care is not
necessary. Rest and attention to the lifestyle factors noted
above—particularly the admonition to avoid sugar—will help you to
recover quickly and, if you stick to them, will significantly reduce
your chances of catching another cold anytime soon.
Getting back to garlic for a moment, a previous article by PreventDisease.com19
gives instructions for a garlic soup that can help destroy most viruses
and help you recover a little quicker. Ideally though, you’d want to
incorporate immune-boosting diet- and lifestyle strategies as soon as
possible to prevent illness in the first place.
So, when should you call your doctor?
Sinus, ear, and lung infections such as bronchitis and pneumonia CAN
be bacterial however, and if so, may respond to antibiotics. If you
develop any of the following symptoms, these are signs you may be
suffering from a bacterial infection rather than a cold, and you should
call your physician's office:
- Fever over 102 degrees Fahrenheit (38.9 degrees Celsius)
- Ear pain
- Pain around your eyes, especially with a green nasal discharge
- Shortness of breath or a persistent uncontrollable cough
- Persistently coughing up green and yellow sputum
