General description and overview of immune boosting, weakened immune system, immune deficiency, strong immunity, increased immunity levels

A strong immune response is vital to maintaining our most valuable asset, a good health. It’s only in the past 50 years or so that we have really begun to understand how our immune system works. We have now gained a much deeper knowledge of how it works, right down to the genes that control it and the building blocks that make up many of the substances that are important for its function.

In this article you will also learn about the natural (read nutritional food) & herbal remedies that have strong immune-enhancing effects. These remedies have been used for centuries and surveys show that more than 60% of us have tried them. Recent research into their actual components has turned up a few surprises and many scientists are becoming interested in serious research in this field.

About your immune system

Your immune system can be divided into two parts based on the structure and position of the organs involved.


First line of defense of our immune system

Your Skin

However soft or vulnerable your skin may look, it’s quite strong when it comes to a fight against the roving bacteria and viruses. Epidermis, the layer of dead cells that form the top part of the skin, plays the pivotal role in the skin’s protective role. This layer is composed of keratin, a protein, which is difficult to break down. Hence, it is generally difficult to for most infectious agents to penetrate the skin, except when it is unhealthy or damaged.

When the germs first land on the skin, they are often stopped by the hair, which help to keep out dirt and microorganisms. Germs that do manage to get past the hair, land on a film of sweat and oil, which is laced with acidic chemicals and beneficial bacteria that together hold back hostile organisms. Then there are also some immune cells like Langerhans’ cells that lie in the epidermis, waiting to ingest unwelcome microbes and alert other immune-team buddies about these attackers.

Skin Statistics

Area covered by skin on the average adult is around 2 sq m; most people grow about 1000 km of hair in a lifetime and approx. 50,000 of dead cells flake and fall off the skin of your body every minute.

Mucus membranes

Mucus membranes are skin-like surfaces coated with secretions that fight germs. They are generally found at natural openings in the body, including the eyes, nose, mouth and reproductive tract; i.e. places that are not protected by your skin. This thick, sticky film produced by mucus membranes traps yeasts, viruses, bacteria, dirt particles, pollen grains, fungus spores and almost anything that tries force its way through these openings.
Over time, there accumulates a mix of mucus and debris at these openings, especially in oral and nasal cavities. Usually, this mixture is swallowed, whereupon stomach acid and pancreatic enzymes destroy most of the germs, or they are carried out of the body by such actions as sneezing or coughing.

When it comes to mucus lining of the respiratory tract, tiny hair-like projections called cilia also come to help by snagging particles and sweeping them away towards the nearest exit (nostrils or mouth).

Hence, these outermost layers (skin & mucus membranes) are generally able to guard the body well against foreign invaders.


Second (inner) line of defense of our immune system

The Innate Immune System - An inside look at the immune system



Our immune system is made up of a complex network of organs which have the power to make, store and aid the team of white blood cells that fights off disease.

All of these are in constant communication with each other via nerves, hormones, chemicals called cytokines and chemokines, and the brain.

Hence, they become one collective organ; if any of them slackens off or brings its full force to bear at a wrong time – or in the wrong place – the whole system can falter.


The Innate Immune System - An inside look at the immune system

These immune components inside the body include:

The Lymphatic System - The lymph vessels comprise a special circulation system throughout the body that carries lymph, a yellowish fluid. Lymph accounts for 25% of the total weight of the immune system and is rich in lymphocytes, predominantly T-cells that battle infection. Small bean-shaped lymph nodes are found throughout the lymph system and cluster where lymph vessels converge in the neck, chest, armpits, abdomen and groin. Each node contains a mesh that filters the lymph to remove antigens. Each node also serves as a hub where lymphocytes gather to fight infection. During this process, the lymph nodes can swell to the point where you can easily feel them

Thymus - The Thymus is a gland situated behind the breastbone and is like a finishing school where baby T-cells multiply and learn to distinguish ‘self’ from ‘non-self’ antigens. This process is not yet fully understood.

Bone Marrow - The Bone Marrow at the core of certain long bones, such as upper arm bone, produces B-cells, natural killer cells, phagocytes and immature T-cells through a process called hematopoiesis.

Spleen - The Spleen, a fist sized organ just above the abdomen, is another place where lymphocytes congregate before being deployed, and where worn-out blood cells and foreign materials are filtered from the blood and some immune cells are activated. It is also a store for red blood cells. Although the spleen is not an essential organ, having it removed or losing it to sickle cell disease makes you more vulnerable to infection, especially from pneumococcus.

Peyer’s patches, oval lumps of tissue similar to the tonsils and adenoids in their function and composition, are found on mucus membranes lining the small intestine.

Tonsils and Adenoids – Once routinely removed during childhood, Tonsils and Adenoids have now gained new respect as important infection fighters. Forming a ring in the back of the throat, these tissues become inflamed as they fill with white blood cells in response to an infection (viral or bacterial) or, in the case of adenoids, to an allergic reaction.

Appendix - Lymphoid tissue begins to accumulate in the appendix shortly after birth and reaches a peak between the second and third decades of life, decreasing rapidly thereafter and practically disappearing after the age of 60. During the early years of development, however, the appendix has been shown to function as a lymphoid organ, assisting with the maturation of B lymphocytes (one variety of white blood cell) and in the production of the class of antibodies known as immunoglobulin A (IgA) antibodies. Researchers have also shown that the appendix is involved in the production of molecules that help to direct the movement of lymphocytes to various other locations in the body. 

Did you know?

The basic function of the appendix appears to be to expose white blood cells to the wide variety of antigens, or foreign substances, present in the gastrointestinal tract.

Liver - The Liver, found in front of the stomach at the top of the abdominal cavity, is not technically part of the immune system. But it is a vital partner that helps protect the body by transforming harmful chemicals such as poisons, pesticides and environmental pollutants into harmless products that can be removed from the body in bile or urine. It also assists the immune system by removing food and microbial products from blood coming from the intestines. These would otherwise stir up the immune system enormously.


The soldiers of our immune system

We have discussed the organs of our body which form the immune system. Now we will discuss the ‘soldiers’ that are mobilized to leap to our defense when under attack.

Antigens – These are the signal givers. Primary function of your immune system is to determine what is foreign and what is part & parcel of your body. Antigens provide the clues. These molecules cover the surface of every cell – whether a native to your body or a foreigner – acting as the cell’s calling card. They are the ones that tell your immune system that the particular cell they are upon is a foreigner and get ready for an attack.

Antibodies – these consist of leucocytes & lymphocytes (white blood cells). Lymphocytes are further divided into specialized soldiers like B-cells or B-lymphocytes which have their own customized jobs. Each give antibody matches an antigen much as a key matches a lock. Once attached to the invader, these antibodies serve as tags that signal other immune cells to swarm and engulf, kill or quickly remove the offending substance.

T-cells – These are the commanding officers of the immune system armed forces. T-cells organize and direct other white blood cells in the fight against infection. Cellular immunity controlled by these T-cells is different form the disease resistance conferred by antibodies.

Are you aware of?

White blood cells are so vital to the immune response; they are used as the key measure of immune system health. Strong immune system generally means normal white blood cells count in your blood – 4000 to 11,000 cells per microliter.

Phagocytes – This is the third type of immune cell and the most effective one. It gobbles up everything unwanted, from dust to viruses. There are 2 types of phagocytes – neutrophils, which circulate in the blood and enter tissues that have become infected, and macrophages, which dwell in healthy tissues and lie in wait for invaders to show up.

Natural Killer Cells – Unlike B-cells and T-cells, these large, circulating immune system cells contain toxic granules that help them to kill their targets on contact. The word ‘natural’ signifies that they are able to kill the instant they are born, unlike T-cells which need to mature.


What happens when you have reduced immunity levels

The simplest explanation is that often there is a lapse between the time a microbe enters the body and the time the immune system conquers it. In the interim, the invader multiplies, killing cells and spewing toxins into the bloodstream. Once a germ begins to take hold and multiply – the incubation period – an infection is under way. Depending on the pathogen, this may take a few days (as with a cold) or many years (as with HIV). People are often infected without knowing it, which is one reason contagious diseases can be spread so easily.

The symptomatic period is marked by the appearance of noticeable signs of illness – fever, for example. Once the immune system gains the upper hand (sometimes aided by medication), the recovery period begins.

There are a number of immune disorders which can be divided up into four main categories:|

Autoimmune disorders

Autoimmune disorders occur when the immune system mistakenly attacks the body’s own tissues and organ cells. So instead of white blood cells attacking harmful antigens and pathogens, the immune system starts attacking healthy cells for reasons that are not yet clearly understood. There are more than 80 different types of autoimmune disorders which include:

Did you know?

Heredity appears to be a strong influence in autoimmune disorders, but, oddly, when these disorders cluster in families, they can surface as different illnesses. A mother may have rheumatoid arthritis, her daughter, juvenile diabetes; and her grandmother, lupus.

Immunodeficiency Disorders

This category of immune disorders occurs when a part of the immune system is not present or not working as it should. Some people are born with an immune deficiency (called primary immunodeficiency), in which case they tend to be more inclined to catching colds, getting infections and allergies than most others. Other immunodeficiencies are acquired either through disease, injury, or certain medications. Some of the most common causes of immunodeficiency include:


HIV (human immunodeficiency virus) and AIDS (acquired immunodeficiency syndrome)


After-effects of chemotherapy and radiation therapy


After-effects of other immunosuppressant medication, such as corticosteroids and drugs used to prevent transplant rejection 





Certain infections such as measles


Severe burn trauma


Many individuals suffer from allergies caused by a hypersensitivity reaction of the immune system to certain allergens in the environment. Some common allergens which trigger this reaction are dust, pollen, pet hair, bee stings, and certain foods. When these antigens enter the body, the immune system tends to overreact and antibodies quickly cause the release of histamine, which results in an allergic reaction. These reactions differ in severity and may include itchiness, hives, rhinitis, and in more serious allergies, swelling of mucous membranes such as in the nose and throat, leading to potential difficulties and anaphylaxis. Common allergic disorders include:




Contact dermatitis


Food, environmental, and insect bite allergies


When cells of the immune system are over-produced and the normal body mechanisms of keeping them in check fail, they become out of control and the result is cancer. For example, when the body over-produces white blood cells, the result is leukemia. Other cancers associated with the immune system are:




Hodgkin's disease


Multiple myeloma


Causes of immune bCauses of weakened immune system, immune deficiency, decreased immunity levels

Immune deficiency may occur for any number of reasons. Whatever the cause, people who have a compromised or weakened immune system tend to be more inclined to catching the flu, colds, or infections that they would normally be resistant to.

After-Effects of Previous Illness, Infection, or Injury:

One of the common reasons for lowered immune functioning is illness or infection. Once your body has been under attack from any sort of illness, the immune system takes some time to fully recover. This can often set up a vicious cycle – though you are beginning to feel better, your immune system is still weakened, thus your body is still vulnerable to another invasion. If you get sick again before the immune system has fully recovered, the illness usually hits harder and recovery takes longer.

Certain illnesses have also been known to weaken the immune system such as chicken pox, measles, tuberculosis, chronic hepatitis, and certain types of cancer.

Take care of injuries!

Injuries such as burn trauma or surgery also tend to lower the immune system's first line of defense (the skin and protective membranes), as the body has to split much of its energy and resources between healing and fighting off infections.

Effects of an Unbalanced Lifestyle:


Poor Diet: Malnutrition and an unbalanced diet are leading causes of a lowered immune system. Research has shown that poor nutrition compromises the lymphatic system, making the body more vulnerable to infection and disease. By ensuring that you eat a wholesome, nutritious diet rich in fresh fruits, and vegetables, whole-grains, legumes and natural oils, you can help strengthen natural immune responses. Also try to avoid excess amounts of “bad foods” such as sugars, animal fats, and highly refined foods, as they tend to weaken the immune system.


Stress: Many studies have shown that stress has a remarkably powerful effect on the immune system. Short term time-limited stresses such as public speaking or a momentary fright tend to temporarily boost the immune system, preparing the body for a potential threat, and giving it that extra boost it may need. However, prolonged stress tends to have the opposite effect and has been shown to significantly suppress the immune system.


Not enough sleep: Too little sleep or poor quality sleep weakens the immune system, leaving the body more susceptible to other diseases and disorders. While it is not fully understood, people who suffer from sleep disturbances tend to have weaker immune functioning than those who get between 7 and 8 hours of sleep each night.


Poor hygiene habits: Simple hygiene habits such as washing hands regularlyand keeping a clean living environment go a long way in helping the immune system protect us from potentially hazardous organisms.

Effects of Certain Medication:

Some medications, particularly immunosuppressant medications such as corticosteroids or medications used after organ transplants (to reduce the chances of the immune system rejecting the new and “foreign” organ), have an adverse effect on the immune system. While suppressing the immune system is the purpose of these medications, it leaves the body open to all sorts of other infections and illnesses.

Chemotherapy also often reduces the body's defenses for some months, both during and after treatment. This is due to the fact that chemotherapy reduces the white blood cell count, which is an essential element of the immune system.

Beware of those deadly Antibiotics

Regular use of antibiotics may also contribute to a weakened immune system – due to the drugs themselves, and because they do not afford the immune system an opportunity to deal with the invading organisms and thus strengthen itself.

Serious Medical Conditions:

There is a group of immune-related disorders known as immunodeficiency disorders. This is where the immune system response is severely reduced or absent altogether. These disorders can be divided into two categories – Primary (also known as congenital) immunodeficiency disorders which are rare genetic defects that an individual is born with or pre-disposed to, or acquired immunodeficiency disorders, which are caused by external causes such as illness, malnutrition, or injury. Some examples of immunodeficiency disorders include:


HIV (human immunodeficiency virus) and AIDS (acquired immunodeficiency syndrome)


X-linked agammaglobulinemia


Selective IgA deficiency


Wiskott-Aldrich syndrome


Chronic granulomatous disease


Leukocyte adhesion defects


Bruton disease


Combined immunodeficiency disease


Herbal & homeopathic remedies useful in immune boosting, weakened immune system, immune deficiency, strong immunity, increased immunity levels

Immune deficiency treatment often depends largely on the cause as diagnosed by a medical professional. For serious immune system diseases such as HIV, drug treatment will almost always be necessary.

If other causes such as dietary or lifestyle-related factors are determined to be at fault, treatment will involve a serious restructuring of eating and living habits, aimed at righting the causes of the immune system problem.

Therefore it is very important to see a specialist to have your immune deficiency diagnosed properly. Try to provide as much background information on your condition as possible so that your doctor can better understand your condition. Blood tests will also likely be required to determine if your condition is the result of an autoimmune disease.

Antibiotics treat bacterial infections when the immune system alone couldn’t mount an adequate response against immune disorders. Therefore a strong and healthy immune system should negate the need for any antibiotics in the majority of situations; therefore it is so critical to always consider strengthening the immune system by taking preventative measures, to help avoid unnecessary medication.

Natural Cures

Natural and herbal remedies can provide much-needed assistance in strengthening the immune system and getting the body’s natural defense mechanisms in top shape. Holistic medicine recognizes that illness is not caused by viruses and bacteria, but by weakened immune systems.

Natural herbal remedies have been used for centuries due to their tonic effect on promoting immune system health, used either as a preventative measure to avoid getting ill, or as a recovery measure to increase the body’s ability to fight off disease and infection.

Different Perspective

Holistic medicine works under the premise that illness is not caused by viruses and bacteria, but by weakened immune systems.

Remember that micro-organisms like the flu virus, TB, etc. are around us all the time, but mostly we manage to resist becoming ill. Boosting the immune system naturally can allow your body to fight off infectious agents without the drawbacks of conventional medication.

There is a wide selection of medicinal herbs well known for their immune strengthening properties that are even safe for children too. Allowing the body to resolve infections without antibiotics will also help to strengthen the immune system against future attacks.

Herbs have been used to treat people effectively for thousands of years – long before anyone knew anything about viruses, bacteria, enzymes, and chemical structures. What they did know was that certain herbs helped for specific conditions or were able to strengthen and protect from illness or immune disorders. While there is no doubt that modern medicine has made huge strides and advances in health care, it is only recently that scientists have stopped their singular search for chemicals that kill bacteria and viruses, and are starting to realize that strengthening the immune system can allow your body to naturally fight off infectious agents - without the drawbacks of antibiotic therapy.

Echinacea purpurea is a Native American herb that has become famous for its antiviral, antifungal, and antibacterial properties. It is an excellent immune system tonic that boosts the body’s immunity by stimulating the production of immune cells.

Another commonly used herb is Astragalus membranaceous (also called 'huang qi'), which has been used for centuries in traditional Chinese medicine to tone the ‘qi’ or life force that we know as the immune system. Astragalus is an ideal remedy for anyone who is prone to recurrent infections such as the common cold, as it is able to increase the body’s resistance and immune response to illness.

Viscum album is commonly known to enhance the immune-stimulating properties of other ingredients, and it encourages repair of damaged cells.

Other natural ingredients with immune boosting properties are Inula helenium, Withania somnifera, Hypoxis Rooperi (extract of African Potato), Mentha piperita, Solidago virgaurea, Crataegus oxycanthoides, Schizandra chinensis, and Olea europea (extract of Olive leaf). All of these powerful and organic ingredients are found in nature’s medicine chest and will go a long way in helping you strengthen your immune system against illness, disease, and infection.

The ingredients are specifically chosen for their ability to address the root causes and not the symptoms in isolation. Remember to source herbal remedies from a reputable company, as therapeutic dosage and ingredient quality is important when using herbal medicines.

Dietary recommendations in immune boosting, weakened immune system, immune deficiency, strong immunity, increased immunity levels

The single most important thing we can do to prevent disease is to eat more fruit, vegetables, beans, nuts and whole grains. These foods contain compounds that influence the makeup of our cells and enhance cell-to-cell communication, most are great sources of antioxidants – chemicals that benefit our health by neutralizing harmful molecules called free radicals.

Because eating too few of the right nutrients can weaken your body and allow germs and disease to gain a foothold, a good diet is the first and most important way to stay well.

We now know that B-cells, T-cells, phagocytes and natural killer cells cannot do their best at quashing cancer cells and other dangerous invaders, such as bacteria and viruses, without strong backup from the vitamins, minerals, fiber and phytochemicals found in healthy foods.


Some of the dietary superstars are:

  • Tomatoes – Along with rich supply of vitamin C, tomatoes are loaded with lycopene, this powerful anti-oxidant gives them their luscious red color and it has convincingly shown to defend the body against cancer.
  • BlueberriesAnthocynanins, the pigments that give blueberries their stunning deep color, have potent immune-stimulating properties. They being antioxidants, anthocyanins protect capillaries from oxidative stress. This helps in smooth flow of immune cells and lymph through these capillaries. Blueberries are also rich in concentrated tannins which prevent E.Coli bacteria from sticking to the cells that line the urinary tract, where they can cause infection.
  • Broccoli – it is rich in disease fighting vitamin C and also sulforaphane, which in turn stimulates the production of enzymes that destroy carcinogens and free radicals.
  • Garlic – garlic stimulates an increase in the production of the immune-system chemicals interleukin-2.

Make a Smoothie

If all this is too much for you, you can make a smoothie of some of this and take daily. 1 cup plain low-fat yoghurt; ¾ cup carrot, orange or grape juice; 30g silken tofu; 1 medium apple, peeled, cored and diced;1 cup frozen berries; ¼ cup chopped ice. Combine yoghurt, juice and tofu in a blender. Add fruit and ice and blend till smooth.

  • Citrus fruits – Grapefruit, oranges, tangerines, lemons, and limes are all excellent sources of ascorbic acid, the form of vitamin C found in plants. As a component of food, this nutritional superstar has myriad immune functions, including enhancing the movement of phagocytes, boosting natural killer cell activity and building and maintaining mucus membranes and collagen, a tissue that plays a vital role in wound healing.
  • Carrots – Carrots and other fruit and vegetables with deep orange color (mangoes, rock melon and sweet potatoes, for example) contain large amounts of nutrients called carotenoids, some of which the body converts to vitamin A. Vitamin A reduces the incidence and severity of infectious diseases by helping to keep the mucus membranes healthy and intact.
  • Salt water fish – They provide protein, necessary for cell growth and repair, and also special fatty acids called omega-3s, which are anti-inflammatory and protect against several cancers.
  • Yoghurt – the living bacteria in protein-rich yoghurt endow this fermented dairy product with more potent immune-enhancing substances than any other food. By attaching themselves to the mucus membranes that line the intestines and reproductive tract, the beneficial bacteria in yoghurt crowd out germs that would otherwise take up residence and cause disease.
  • Foods to cut back on should include prepared salad dressing, beef, coffee, frozen yoghurt, and high fat diet.

Dos and don'ys (precautionary measures) in immune boosting, weakened immune system, immune deficiency, strong immunity, increased immunity levels

Here are some of the lifestyle factors that you can employ to keep your immune system in peak condition and able to ward off recurrent infections.

Make sure that you get enough sleep – this means both an adequate quality of sleep as well as an adequate length of sleep. Sleep is one of the most important factors in maintaining a strong and healthy immune system
Ensure that you have a wholesome, nutritious diet rich in fresh fruits, and vegetables (preferably organically grown), whole-grains, legumes and natural oils.
Exercise and keeping active is not only good for your body and your mind, but also helps to optimize immune functioning. In addition, regular moderate exercise will help to relax you and will also encourage healthy sleep. Not to mention, the more we move, the more our lymph is circulated - thus, the better this system can function.
Maintain a healthy weight. Being too thin or overweight can equally depress the immune system.
Stress  is also bad for the immune system. While small amounts of stress can be beneficial, prolonged stress depresses the immune system. If you are experiencing anything like this it is important to treat it. Anxiety and depression can also compromise the immune system – a healthy mind leads to a healthy body.

Laugh till you die…

…as you will live longer. The chemicals produced when we are happy have receptor sites on cells all over our body so happy minds can make happy, healthy cells.

Don’t smoke and avoid secondhand cigarette and tobacco smoke. The chemicals contained, even in secondhand smoke, all depress the immune system and have a negative impact on its functioning.
Reduce exposure to germs. Practice good hygiene habits such as washing your hands before meals and after going to the toilet. Stay away from people who are sick and, where possible, keep your children in smaller day care centers or crèches.
Avoid the excessive use of antiseptic and antibacterial soaps, sprays, and other detergents. While these may kill bacteria and other organisms in the short term, they also contribute towards the development of resistant strains of bacteria which at times can reach epidemic proportions. Use natural ingredients such as Tea Tree oil and certain aromatherapy essential oils. Do not keep children ‘too clean’. A certain amount of ‘healthy dirt’ is good for the immune system!
We are surrounded by toxic chemicals and pollutants wherever we go, at home and in the environment. Where possible use safe non-toxic chemicals at home, in your toiletries and in your gardens.
Avoid excessive sun exposure, as this can depress the immune system – this is why cold sores are so common after spending time in the sun. Sunlight is necessary to produce Vitamin D so don’t avoid it entirely, just be sensible about the time of day and length of time you spend in the sun, and wear sun block.
Avoid the vicious antibiotic cycle. While antibiotics may be necessary in some cases, they are generally over-prescribed and used as a first option instead of a last resort. Try exploring natural health options, as there are many herbs with a long history of use that are well-known to strengthen different parts of the immune system.
