How to Build a Bulletproof Immune System

Many people today are dealing with physical exhaustion, weakened health, and compromised immunity after prolonged illness.

Here’s the truth: supplements, good food, and exercise alone aren’t enough.

If you don’t understand what a healthy state truly is and how disease develops, you’ll keep experiencing physical exhaustion, poor immunity, and vulnerability to future illnesses, no matter how many vitamins you take.

Let’s fix that.

The Germ Theory vs. Reality

Modern medicine teaches that diseases are caused by “pathogens”: bacteria, viruses, or fungi that attack your cells. When these invaders multiply, they cause inflammation and infectious diseases.

The body responds by producing antibodies to identify and destroy these pathogens. Strong immune systems eliminate threats before they multiply. When a pathogen is new, the immune system produces many different antibodies until it finds one that works, then “remembers” it for next time.

This is the basic principle behind vaccination.

The microscope revolutionized medicine by helping us discover bacteria and confirm this theory, leading to breakthroughs in addressing infectious diseases.

But there’s a problem.

Science is not omnipotent, and germ theory has blind spots.

The same scientific experiment can be explained through different philosophical and consciousness foundations, leading to completely different theoretical systems.

Modern medicine was built by Western minds oriented toward mathematics, logic, conquest, and battle. Their approach treats disease like war—fighting, destroying, conquering. They view the human body as a mechanical system where parts can be repaired or replaced through surgery.

Eastern medicine (Chinese and Indian) built a different healing system. They focus on restoring chemical balance, viewing the body not as a machine but as an ecosystem. They emphasize prevention over treatment.

These different systems produce different results. Modern medicine is effective for reducing symptoms and treating immediate infections, but patients frequently relapse into chronic conditions, becoming dependent on medication without a definitive cure.

The Real Root Cause of Disease

Germ theory has a fundamental flaw: it’s incomplete.

If we explain illness from a broader perspective—combining Eastern and Western medicine—we get a different theory that helps you understand disease development and build true resistance.

Pathogens are not the only cause of illness.

Your body has approximately 30 trillion cells and about 38 trillion bacteria. Most of these bacteria are “good”—they help your body function healthily.

These bacteria live in your intestines, skin, mouth, and mucus fluids. If each bacterium were a person, your body would be a planet where cells and bacteria coexist in peaceful symbiosis.

A bacterium is “good” when it absorbs substances from its environment and excretes substances beneficial to your body. Intestinal probiotics, for example, help digest and ferment difficult-to-digest foods into absorbable nutrients. Without them, these foods become toxins causing indigestion and digestive disorders.

A bacterium becomes “harmful” when it excretes toxins that poison and weaken cells, leading to inflammation and ulcers.

A healthy body is an ecosystem where beneficial bacteria dominate and harmful bacteria are few. Illness occurs when harmful bacteria multiply.

Here’s the crucial insight: The root cause of illness is the proliferation of harmful bacteria instead of beneficial ones.

But why do pathogens multiply instead of good bacteria? Understanding this mechanism is the key to lifelong health and immunity.

The Ecosystem Perspective

Stop viewing the body as a machine. View it as an ecosystem where individuals (cells, microorganisms) live together.

In nature, animals multiply only when they live in an environment with sufficient food, water, and few natural enemies.

The same principle applies to your body’s cellular ecosystem. Pathogens develop only when conditions favor that microorganism.

These conditions include food (chemicals, organic substances in the body), energy fields (bioelectromagnetic fields), temperature, acid/base concentration, and oxygen levels.

Real-world examples:

A child with cavities isn’t suffering from bacteria alone, they’ve left food debris on their teeth. Bacteria eat this debris and release acid, which erodes tooth enamel. Without the favorable environment of food debris, pathogens can’t develop and cause cavities.

People who drink alcohol regularly create many toxins flowing to the liver, making it a suitable environment for viruses to develop—causing hepatitis, especially hepatitis B.

People with stomach and intestinal ulcers eat unhealthy, difficult-to-digest foods that stick to intestinal walls. This creates an environment for pathogens to multiply, secreting toxins that cause inflammation and ulcers.

The fundamental truth: Illness isn’t just from bacterial attacks. The root lies in the body’s biological environment changing to favor harmful bacteria.

A healthy person has stable chemical balance in the body. Even when exposed to harmful pathogens, these invaders cannot multiply due to lack of a favorable environment. This person has good immunity.

Conversely, someone with poor immunity and underlying conditions has many toxins in their body. Wherever toxins concentrate is where bacteria multiply and cause inflammation.

Your Body’s Detoxification Pathways

Toxins naturally concentrate in your body’s elimination mechanisms:

1. Vomiting

Occurs when the digestive system receives substances too toxic to absorb.

2. The Liver

The site of nutrient metabolism and blood filtering. Toxins filtered by the liver are deposited into bile flowing into the intestines. Too many toxins cause chronic liver inflammation and hepatitis.

3. The Kidneys

Filter fluid-water and remove blood toxins into urine. Excess toxins cause chronic kidney inflammation, kidney failure, diminished physiological function, and genital infections.

4. The Respiratory System & Skin

When liver and kidneys operate at full capacity but toxins remain, they’re eliminated through the respiratory system and skin. Toxins released through the skin cause acne, boils, and skin inflammation when excessive.

In the respiratory system (lungs, nose, sinuses), high toxin concentration causes bronchitis, pneumonia, sore throat, and sinus inflammation. Coughing and phlegm are natural reactions to expel these toxins.

5. The Heart

If all pathways are overloaded, the heart beats faster to move blood more quickly, increasing toxin elimination speed. But faster heart rate means increased blood pressure. Over time, this leads to blood clots, myocarditis, heart failure, stroke, and death.

More young people today are experiencing stroke, myocarditis, and heart failure from this exact mechanism.

6. Long-Term Accumulation

If toxins still remain, they accumulate in the body. Long-term accumulation leads to cellular dysfunction, eventually resulting in cancer.

All chronic diseases—hepatitis B, stomach ulcers, allergic rhinitis, arthritis—are consequences of prolonged toxin accumulation.

This is why eliminating bacteria through antibiotics only provides temporary relief. If the root cause (internal organ toxicity) isn’t eliminated, pathogens will multiply again quickly.

Worse, focusing only on eliminating pathogens through antibiotics, symptom-reducing medications, or vaccinations introduces more toxins, causing further immune system decline.

Especially alarming: when the body environment changes, organisms develop adaptations to the new chemical environment. Beneficial organisms can become harmful, and pathogens become antibiotic-resistant. The medical community has only recently recognized this.

The Detoxification Equation

Good health and immunity come from recognizing your toxin accumulation status and eliminating those toxins, restoring chemical balance in the body.

Here’s the equation:

Toxin cause/imbalance = Filtered toxins (toxin filtering rate) + residual toxins/biochemical imbalance in the body

To detoxify, you need to:

1. Reduce toxin-causing agents
2. Improve your body’s toxin-filtering ability

The 7 Sources of Toxicity

1. Animal-Based Food Contamination

Early humans, before discovering fire, were herbivores. Give a child fruit, and they eat it instinctively. Give them a live animal like a cat or dog, and you’ll wait forever—they don’t naturally eat it like lions and tigers.

Fire allowed humans to process meat into palatable food, but meat remains difficult to digest. When eaten, meat settles on intestinal walls where it decomposes, ferments, and produces toxins that seep into the blood and release foul-smelling gases.

Worse, industrialized livestock farming injects animals with growth hormones, stimulants, and harmful substances—all entering your body through food.

The result: Children eat more meat, consume more hormones, and experience earlier puberty.

Solution: Reduce red meat. Transition to fish, eggs, and especially plant-based foods like vegetables, fruits, brown rice, and sweet potatoes. Vegetables and fruits are excellent sources of fiber—food for beneficial bacteria to multiply.

2. Water Contamination

Your body is 70% water, making water the most important biochemical substance.

Here’s what’s in your tap water: A chemical solution containing extremely toxic substances—Fluorine and Chlorine (water disinfection agents—a direct result of germ theory).

These are neurotoxins that affect your brain, especially the pineal and pituitary glands.

Clean water is increasingly difficult to find. Rainwater contains toxins from vehicle exhaust and factory emissions. People living near industrial areas suffer more illnesses and cancer.

Solution: Drill for groundwater and become self-sufficient in water instead of using industrial water pipelines. Stay away from industrial beverages like soft drinks and carbonated drinks—they’re full of preservatives, colorings, and additives.

3. Air Pollution

As the economy develops, more waste enters the air, causing rhinitis, sinusitis, and pneumonia.

Solution: Always wear a mask when going outside. Rinse your nose 1-2 times daily with saline solution to clean your respiratory tract. Stay away from cigarettes and tobacco—their toxins are extremely strong and immediately seep into blood and spread throughout the body.

Crucial: Passive smokers absorb more toxins than smokers themselves. Quit to protect your family and loved ones.

4. Food Processing Contamination

Humans are the only species that cooks and processes food. All animals eat raw.

Cooking makes nutrients easier to absorb, but some substances transform from beneficial to toxic.

The prime example: Fats and oils. When cooked at high temperatures, they transform into saturated fats—toxic substances affecting the cardiovascular system.

Whether vegetable or animal oil, frying with oil will toxify your body. If your body is relatively “clean,” you’ll be sensitive to these substances—eating meat or fried foods will make you feel tired, produce more oil on your skin, and break out in acne.

Solution: Try eating raw foods, starting with vegetables and fruits. If cooking, limit frying and instead boil or steam for easier digestion.

5. Industrial Food Contamination

Industrial foods are preserved for long periods using countless preservatives, additives, and colorings. They have altered chemical compositions like MSG, artificial sugar, and refined starch.

The reality: Business goals are to generate sales, so these substances make food feel “tasty” but toxify your body. Industry uses pesticides, stimulants, and herbicides on vegetables and fruits.

Advice: Stay away from industrial foods!

6. Yin-Yang Imbalance Toxicity

A healthy body has chemical balance—what Eastern medicine calls yin-yang and five elements balance. Imbalance creates toxins.

Imbalance can be caused by:

• Sudden temperature changes (catching cold or heat)
• Imbalanced eating (too hot or too cold)
• Five elements imbalance (too sour, spicy, salty, sweet, or bitter over long periods)

Solution: Study traditional medicine for stable, long-term health and extended lifespan.

If that’s not possible, remember these basic balance principles:

1. If you feel internal heat, supplement cooling substances; if cold in hands and feet, supplement warming substances
2. Always balance all five flavors: Bitter, Sour, Spicy, Salty, Sweet
3. Balance protein, carbohydrates, and fats
4. Eat moderately—not too little or too much

7. Energy Field Toxicity

Energy waves are electromagnetic waves at different wavelengths. Pathogens develop differently with each type of energy. Ultraviolet wavelengths, for example, can destroy up to 99% of pathogens, especially viruses.

Beyond pathogens, human body cells are also affected by these energy waves. Electromagnetic toxicity is real but not deeply researched by modern science.

Sources include:

• Electronic devices (computers, phones, TVs, WiFi, appliances)
• Cosmic radiation from changes in the moon, sun, and star systems

Research shows human cells are affected by extremely low frequency wavelengths corresponding to Earth’s low frequency bands. Household electronic devices operate at 50-60 Hz frequencies, which can affect your health.

Advice: Stay away from these electromagnetic wave sources, especially when sleeping—that’s when your energy field is weakest.

Another powerful energy source: your thoughts and mindset. Positive thoughts attract positive energies; negative thoughts attract low-vibration energies.

Energy waves alter chemical substances from endocrine glands (pineal, pituitary, thyroid, adrenal). They’re electrical signals that activate the release of chemical substances, like your nervous system.

Depressed people are always prone to illness and have poor immunity. Happy, positive thinking is the first step to good health.

How to Detoxify and Heal

For those currently ill with poor immunity and toxin-heavy bodies, here are basic methods to detoxify, increase immunity, and heal.

Understand Self-Healing

When infected with toxins or pathogens, the body becomes feverish and inflamed. Fever activates the immune system to produce antibodies that destroy pathogens. Inflammation removes dead, toxic cells and begins tissue recovery.

Fever and inflammation are natural detoxification responses.

But for those with too many toxins, detoxification channels become overloaded, and the body retains toxins. When sick, you shouldn’t introduce many substances through eating—this creates more toxins and makes recovery harder.

The Fasting Principle

A common mistake: forcing sick people to eat a lot to “gain strength for fighting the illness.”

Observe dogs and cats—they never eat when sick. Fasting is one of the body’s natural healing methods.

When fasting or eating lightly, your body searches for energy through reserve tissues. It seeks out cells and tissues containing the most toxins to eliminate and extract energy.

This explains why alcoholics become alert when drinking and drunk when craving—when they stop drinking, toxins are being eliminated. People with meat-eating habits feel tired when lacking meat because that’s when toxins are being eliminated.

To heal: Rest and eat lightly. For detoxification, apply intermittent fasting—one day per week or month.

Warning: Those with severe illness and weakened bodies should NOT apply fasting. They have too many toxins, and fasting could cause shock or stroke from eliminating too many toxins simultaneously.

Advice for severe cases: Rest and eat lightly—fruits, vegetable juice, vegetables, brown rice. Limit meat, especially red meat. Do not eat fried or oily foods.

Enhance Detoxification

Supplement acidic substances to support the liver and salty substances to support the kidneys.

Liver support: Lemon, starfruit, orange, kumquat, tomato, and rankin caulis.

Kidney support: Nutgrass galingale, phyllanthus urinaria, and Vietnamese coriander.

Vietnamese Herbal Remedy

For weakened bodies or immunity boosting, use this herbal remedy:

1. Licorice - Sweet and spicy, neutral nature. Detoxifies, unblocks 12 meridians, benefits qi and blood
2. Phyllanthus urinaria - Sweet and salty, slightly cold. Clears heat, promotes urination, detoxifies, reduces inflammation
3. Nutgrass galingale - Spicy, slightly bitter and sweet, neutral. Kidney tonification, improves physiology, regulates menstruation, treats reproductive tract diseases
4. Lemon (or kumquat or orange) - Sweet and sour, cooling. Clears heat, detoxifies, sterilizes, brightens eyes
5. Goji berries - Sweet, neutral. Tonifies liver and kidneys, nourishes the body
6. Jujube - Sweet, neutral. Tonic that improves vital energy and supports 12 meridians
7. Turmeric - Spicy and bitter, warm. Breaks blood clots, improves blood circulation, detoxifies, heals wounds. Pregnant women should not use.
8. Lotus seeds - Sweet and waxy, neutral. Tonifies the heart, calms the mind, nourishes weakened bodies
9. Mugwort - Bitter and spicy, warm. Circulates qi and blood, detoxifies, recovers wounds

Preparation: Use equal amounts of all ingredients. Cook and drink daily. Use only 1-2 pieces of lemon/kumquat—too sour is not good. For low blood pressure, reduce lotus seeds and turmeric, add one piece of ginger.

Dosage: Drink about one coffee cup of concentrated herbal water daily. Too much causes internal heat and “herbal intoxication” (similar to drinking many cups of strong tea daily).

Storage: Keep herbal water in the refrigerator. Daily, pour one coffee cup of concentrated herbal water into a large bottle and dilute with 3-5 times the water volume to create a daily health-tonifying tea.

Final Thoughts

Health is chemical balance, what Eastern medicine calls yin-yang and five elements balance.

Many people feel confident about their health, feeling healthy—but that’s only physical strength. After long periods of toxin accumulation, when illness strikes, it progresses quickly, worsens, and doesn’t recover.

All these illnesses come from eating and living habits in today’s technology and engineering age.

Humans pride themselves on being more civilized than ancestors from hundreds of years ago. But ask yourself: Why does this more civilized era produce more people with myopia, diabetes, obesity, hepatitis, cavities, chronic diseases, and cancer?

Are we really civilized?

Since ancient times, elders taught: “Illness comes from the mouth.”

If humans continue searching for health solutions by blaming genes and pathogens, fighting them without changing lifestyle and personal habits, illness will not let us go.

At that point, illness is not misfortune, it’s your choice.

Remember the teachings of Master Tue Tinh:

“Preserve essence to nourish qi, sustain the spirit Purify the mind, restrain desires, practice cultivation”
