Parasites, and how they impact on our health          


There are many types of parasites that can invade our environment as well as our body.  Here I will look at those that colonise in our body.


Human parasites are organisms that live inside our body; we then become their Host!  These parasites are unable to produce food themselves, so they depend on us for their survival.  They eat our food and nutrients, they drink our blood and they can destroy our tissues and cells whilst producing toxic waste that makes you feel very ill.

Human parasites are everywhere in our environment, so it is easy to become infected. The following is just some of the ways people can acquire parasites:

Ø  Insect bites

Ø  Handling raw meat and fish

Ø  Animal or human faeces

Ø  Eating raw or undercooked pork, beef or fish

Ø  Walking barefoot outside/indoors

Ø  Having contact with an infected person – this includes kissing, touching/shaking hands, sexual contact.

Ø  Contaminated water

Ø  Eating contaminated raw fruits and vegetables

Ø  Emptying soiled litter pans especially cats – must wash your hands!

Ø  Not washing hands when you have used the toilet

Ø  Eating food/meals that infected people have prepared – maybe they did not wash their hands

Ø  Inhaling contaminated dust – especially parasitic eggs or cysts

Different Types of Human Parasites:

All human parasites consist of tiny protozoa and amoebae, which are seen under a microscope, not by the naked eye.  This also includes parasitic worms and flukes, which are larger.  Parasitic worms are in most cases taken on board when you eat contaminated meat.  The tiny protozoa and amoebae are spread to people by water, air, food, animals, human contact and insects.  They most troublesome and cause major health problems if not eliminated.  They can travel from the intestines to the bloodstream, muscles and vital organs, where they create damage to the host.  Some of these tiny parasites will actually attack the organs, including the heart.

These parasites are very light and float in the air where they are inhaled.  Whilst in their resting stage or cyst stage, they are very infectious.  They have been linked with cancer, rheumatoid arthritis, asthma, diabetes, multiple sclerosis, irritable bowel, cardiovascular problems and many other health disorders

One young girl I met who had experienced 4 cardiac arrests and was also diagnosed with possible fibromyalgia (pain throughout all her muscles and tissues), she had been infected by consuming liquids whilst travelling overseas.  The living organism was literally attacking her vital organs including her heart!

Blood tests need to be taken to ascertain what types of parasites and bacteria’s are present.  Live Blood Analysis (LBA), can also be taken by specialised technicians to ascertain the condition of the blood.

A few of the more commonly known parasites are:


These are found in dogs and cats and rarely in humans.  If you are infected with this parasite you may have swallowed fleas that were already infected with tapeworm larvae.  Interestingly humans do not always show any symptoms, but if the worm takes up residence in the intestines it can eat away all your nutrients and off load toxic waste in your system.  Anyone with dogs and cats at home needs to observe hygiene.

However if you do experience the following symptoms it could indicate that tapeworm is present:  dizziness, hunger pains, allergies, bloating and wind, general digestive problems, mineral imbalance.


This worm is usually acquired into the host by drinking water that contains hookworm larvae, or if you eat vegetables and fruits that have become contaminated.  Once in the host the worm will hook onto the intestinal lining where it drinks your blood!  Microscopic examination actually shows that this tiny worm actually has teeth!  They can live in your body for up to 15 years with a female producing around 6-7 million eggs during her entire lifespan!  These eggs don’t hatch inside your body; they are passed out through normal bowel movements, hence the importance of a healthy bowel with daily elimination 1-2 times.

If you have hookworm invasion you may experience weakness, anaemia, nausea, diarrhoea and abdominal pain.


This tiny worm lives in your colon and is the most common worm found in our bodies.  It lays eggs outside of the host body also!  You can acquire this worm through unclean hands, and dirty clothes and bed sheets.  If you have got pinworms you may experience anal itching and irritation.

After copulation the male dies and the female will make her way to the anus where she lays around 5,000 – 10,000 eggs.  Sometimes travelling outside of the anal area for a few centimetres and lays more eggs.  Upon completion of laying eggs here she will crawl back inside and dies.  This can contribute to the anal itching and you can continually reinfect the area by constantly scratching.  The eggs will attach to your skin or under your nails, if you must scratch do it over a tissue or material to counteract this reinfection.  Pinworms will live around 2 months.  These worms can also travel to the vaginal area in women and cause irritation and inflammation.  They can cause granulomata in the uterus and fallopian tubes.  This little parasite is very difficult to control and reinfests very quickly and frequently.  Some tests have shown that it can migrate towards the appendix, urinary system and peritoneal cavity.


You can become infected with roundworm by ingesting the eggs, which are in soil that is on your fruit and vegetables.  The eggs live in your intestines and gravitate to various organs where they cause severe damage.  This is one of the most commonly acquired parasites in the world.  It is actually quite large and can be as thick as a pen or pencil often around 16mm in length.

You would expect to experience weight loss, weakness and fatigue, often abdominal pain and possibly infections.

Fish Tapeworm

This worm is found globally and is the largest of all the tapeworms growing sometimes up to 13 meters long!  You will acquire this if you eat undercooked fish that contain the worm’s larvae, also by handling raw fish and not washing your hands thoroughly.  It can also be ingested via smoked or pickled fish.  It literally sucks onto your intestinal wall, and here is thrives and lives until it grows into an adult.  Surprisingly it does not cause a lot of damage to the intestinal wall but it will feed off glucose and is often present in cases where hypoglycaemia is experienced.  It appears to love vitamin B12 and will leach this from your system, thereby contributing to anaemia.  A very active tapeworm that produces billions of eggs during its lifetime in your gut!


These tiny parasites are known as Bilharzia - blood flukes.  They inhabit your blood vessels bladder and intestines and can pass their eggs through your urine and faeces.  The Host is infected by skin penetration, often through the feet, when in fresh water where certain types of snails that carry schistosomes are living.  Also rivers, lakes that are infected.  Fresh water becomes contaminated by Schistosoma eggs when infected people urinate or defecate in the water.  The eggs then hatch and if certain types of snails are present in the water, the parasites grow and then develop inside the snails.  The parasite leaves the snail, enters the water and here survives for up to 48 hours.

Once you are infected, you may not even be aware of it, however if you begin to experience fever, chills or perhaps start coughing, experience muscle aches, itching, then your body has developed a severe reaction to the eggs, but not the worm itself.

Becoming reinfected constantly can damage the liver, intestines, your lungs and bladder.

This little critter often occurs in the following global areas:

Africa - especially southern, Saharan, the Nile, Lake Malawi. South America – especially Brazil, Venezuela, Southern, China. South East Asia - such as the Philippines, Indonesia, Cambodia, Laos, Mekong delta and Japan, Caribbean -Antigua, Martinique, Saint Lucia, Dominican Republic, Guadeloupe, The Middle East – Iran, Iraq, Syria, Yemen, Saudi Arabia.

So, if you travel to any of these countries do not go into fresh water, lakes, rivers, canals etc.  If you have already been exposed I recommend you get a blood test, especially if you are experiencing any of the symptoms outlined here.

Liver Fluke

This is a flat type worm that attacks your liver!  It can irritate and cause inflammation and even make tiny holes in your liver.  You acquire this dreadful parasite by eating undercooked fish, contaminated vegetables, or even eating crops where human faeces have been used as a fertilizer.  For all you swimmers out there, beware!  Do not swim in dirty contaminated water whether home pools, rivers, streams etc.  Also avoid drinking contaminated water.  Liver Fluke can live in your body for as long as 30 years and while it takes up residence here it will create the following symptoms:

Enlarged liver, you will experience pain in the right side of the body, oedema, vertigo, bile stones, and cancer.


Entamoeba histolytica – which produces’ amebiasis.  It is found in water and damp environments, including soil, contaminated fruits and vegetables.  It spreads through faecal contamination and is a one-celled organism.  Any crops that are fertilised with human faecal waste will be contaminated.  People who do not wash their hands when they have used the toilet can infect themselves and others through their poor sanitation habits.  It can also be spread with unsafe sexual practices.  Interestingly most people don’t display symptoms but when they do you would experience abdominal pain, bloating, diarrhoea, weight loss, weakness and fatigue.

Toxoplasma gondii – this organism invades your central nervous system.  Again you acquire it by eating undercooked meat or if and when you handle infected kitty litters, which contain eggs.  It is a very common parasite and when viewed through a microscope is crescent shaped.  If a person has a very weak immune system they are more likely to experience symptoms such as fever, chills, fatigue, headache, otherwise many people appear to have antibodies to counteract it.

Giardia Lamblia – resides in your intestines or your gall bladder.  It is spread again by faecal contamination and through contaminated water.  People who have poor hygiene and don’t wash their hands regularly, who have unsafe sexual practices all trigger this organism to spread and contaminate the host.  This organism can actually be found in your tap water!  This is because it is resistant to chlorination.  It is also found in natural streams.  Probably another good reason to filter your water!

Any symptoms you may experience are similar to the other organisms such as abdominal pain, bloating, diarrhoea, mineral/vitamin deficiency, since nutrients will be leached from your system.

Many of these parasites are challenging to diagnose since symptoms can be similar and sometimes vague.  In a few cases some people may not experience any specific symptoms at all.  However if a gastrointestinal tract problem is present you can pretty much guarantee that some type of parasite is present and causing irritation and poor health.

Life Cycle of the Parasite

Parasites have a life cycle whereby the egg is initially expelled by a bowel movement into soil and then nature carries that soil and egg into the rivers, streams, and ponds when it rains.

A tiny Miracidia hatches from the egg in the water.  This little organism as cilia (like tiny hair like fingers) and can swim.  Instinctively if finds snail host almost immediately, if it fails to do this it will be too exhausted and not survive.  The next development stage is called Redia, which is inside the Miracidia.  When the Redia is expelled (these are called Mother Redia in shape of little balls), and each in turn has “daughters” inside of them which survive for approximately 8-10 months whilst inside the snail.  Redia lives off the lymphatic spaces within the fluids of the snail.  The “daughter” Redia develops over time to become the next stage known as Cercaria.

The Cercaria has a tail, which they use to exit the snail to swim to a plant.  When the snail is feeding off a plant the Cercaria latch onto the plant with sucker mouths and begins to form a cocoon in a few minutes, at this stage their tail breaks off.  These 2 walled cysts that they have created (known as a cocoon) are called the Metacercaria.  The outer layer is very sticky so whilst it is stuck to the plant you can ingest it if you eat the plant without thoroughly washing the plant/vegetable first.  The cyst is then in your mouth!  This cyst wall is protective of the contents within it and almost unbreakable, therefore protecting it whilst you chew.  Since it has a keratin like coating this prevents digestive enzymes and stomach fluids from fully digesting it.  When this cyst reaches your duodenum, it will come into contact with your intestinal fluids and they dissolve the cyst wall and free it.  It can then attach itself to your intestinal lining and begin feeding off you and growing into an adult form.  Here is can thrive and live indefinitely producing around 1000 eggs with each bowel movement!


From a naturopathic standpoint I recommend people take herbal/homoeopathic remedies and run through a short course of worming every year.  It is so easy for any of us to become contaminated even if we are very hygienic.  It is often other people and our surroundings that can contaminate us.

If parasites are not cleared from the body on a regular basis they will simply thrive and grow – they multiply inside you and literally eat your food, drink your blood and attack your vital organs!

The above list or parasites is certainly not complete, there are over 4,000 parasites that we are presently aware of!  Out of these there are several hundred that love to inhabit our body and some can live here quite happily for your entire lifetime!

Your body of course will do its best to adapt to these invaders and all the varying toxins that they excrete.

Since naturopaths look at the Stomach as the Seat of Disease, I aim primarily to get the entire gastrointestinal tract free of toxins and the digestion, kidneys and bowel working efficiently, only then can you experience more vitality and eliminate some of your symptoms.  There are no side affects by taking herbal/homeopathic remedies for worming, but there are certain herbs that are used in accordance with varying symptom profile for specific types of parasites and they need to be dispensed professionally for the correct results you are seeking.  Remedies to normalise digestive enzymes, aid in assimilation and absorption of nutrients, for detoxifying kidneys and creating regular bowel movements are also incorporated into the healing regime.

Other symptoms where you may suspect parasitic infestation are:

Ø  Diarrhoea, which is foul smelling often becoming worse as the day progress’s.

Ø  A sudden change in your bowel movements.

Ø  Itching around the nose, ears, and anus – especially at night.

Ø  Food allergies

Ø  Anxiety and constant hunger, yet experiencing weight loss

Ø  A lot of rumbling and gurgling in your stomach even when you have not eaten or you are experiencing hunger.

Ø  Often huge appetite and a feeling of not being fully satisfied – constant hunger.

Ø  Anaemia

Ø  Heartburn or chest pain

The most troublesome parasites I have treated recently, including my colleagues are Dientamoeba fragilis, blastocystis hominis and Anisakiasis.  There appears to be more people presenting with the former and even medical doctors are failing to resolve it.  Regular herbal formulas that have been used for many years no longer help with this organisim.  I have had to create a new formula to slowly kill off the entire colony since most people have very chronic cases when they present.  Blasto on the other hand is far more common and easier to treat mainly with homoeopathics but sometimes herbs also.

Dietamoeba may not show up in the first 1-2 tests so daily stool tests may be required - a blue dye is commonly used to detect this parasite.

All in all I do stress the importance of worming and taking anti parasite herbs once a year with natural remedies, and ideally the entire family should undergo treatment at the same time otherwise it will be a useless exercise, parasites will continue to be past from person to person. I do recommend you see a experienced Naturopath/Herbalist who can help you with this disorder they can organise functional lab tests if required including stool tests – particularly if this is a chronic case.  Labs will not send results back to you, they will only run the tests if you are returning to a GP or Naturopath – the former of course is not trained to administer herbs or homoeopathic’s.

I have seen good results with people who are compliant and take their herbal remedies consistently over a given period of time.  Stopping and starting with remedies is wasting your time and money and getting you nowhere.  People put up with bowel problems which could relate to parasitic infestation for many years, sometimes as long at 15 or 20 years!  Suffering and enduring a myriad of symptoms in the GIT whilst a constant hatching of eggs takes place with these organisms.  Remember it’s not just the intestines where parasites inhabit; they can attack various organs/systems in the body.  Anyone with domestic animals, or even living on country properties should definitely worm yearly including their pets.

When eliminating motions can sometimes recede and pulling it away with tissue paper often shows you a worm attached to it.  Sometimes the worms appear to “hold on” and stop the motion from being eliminated.  Worms can be as long at 18cm attached to a motion and occasionally one worm will attach to 2 motions so you have difficulty eliminating the 2nd without pulling it out.  This happens more often if the motions are very dry.

Some people seek to use pharmaceutical worming products – there are plenty on the market, but some can be irritating to the intestinal lining due to chemical activity and can create other symptoms like constipation, abdominal gas or pain.

If you stop taking remedies too soon because you experience improved bowel function and less bloating you may allow the breeding cycle to continue.  I recommend that you follow through for at least 3 months and also a 2nd stool test is best obtained.  Getting rid of the eggs is the major problem since they are so tiny and constantly hatch and the breeding cycle goes on and on.


All your plant foods need to be washed thoroughly, immerse in bowl filled with water and white vinegar for at least half an hour then rinse of with filtered water.  Make sure you never handle any other food when touching animal food.  Take great care here.  Cook food well and if you eat raw make sure it is well marinated.

I am available for private consultations including after hours phone and skype consults for those who live too far away from Sydney.  Please call me to arrange.
