Dr. Clark's protocol is a therapy for global well-being.

It is used to protect your health from external and internal agents with natural methods for detoxification of our body.

Dr Clark was a biologist, a biophysicist, a Canadian researcher. She revalued ancient methods in harmony with nature for the maintenance and restoration of health.

Dr. Clark's approach is that of "Self Health". Self Health means being able to take care of your own health.

The health method developed by Dr. Hulda R. Clark helps to improve one's physical and mental condition by simply removing the two fundamental factors that cause our imbalances: PARASITES AND POLLUTANTS.

Currently, most of the population has an accumulation of toxins as they surround us on an environmental level as well as in the food, water, dental materials etc. This also makes us prone to excessive proliferation of pathogens.

The basis of Clark therapy is the detoxification of our body and the elimination of pathogens by natural means.

This method can be used both for preventive purposes and to improve numerous symptoms.

Dr. Clark believed in simplicity. She was convinced that each of us is able to regain our health. She believed in the power of nature and all that naturally surrounds us.

Dr. Clark was a person out of the ordinary, an out-of-the-box thinker.

She said that by removing obstacles from the body. immunity restores itself and begins to function properly.

These obstacles are pollutants such as heavy metals, wheelbearing grease, motor oil, rubber and plastics, benzene, PCBs, isopropyl alcohol, malonic acid and radioactivity and pathogens such as parasites, bacteria, viruses and fungi.

With her invention and  diagnostic tool she could test for anything inside and outside the body. With this method she could see in a non-invasive way the presence of intruders in her own body and in other bodies. This device is called the : "Syncrometer".

Dr. Clark said that her therapy is compatible with every other therapy and therefore can be used with other therapies.

Dr. Clark was probably the world's most experienced authority on parasites and studied in detail what damage the parasites cause in humans.

For her study on parasites, she was ridiculed by many professionals, although today more and more professionals recognize that an immunodepressed subject, be it a person, an animal or a plant, will also be strongly parasitized and ill.

Dr. Clark’s studies regarding what causes imbalances and therefore diseases in humans cover a   360 ° level and are on the  following topics:

  • TOXICOLOGY (Metals, Solvents and Pollutants, Dyes)

She always found the causes of the disease with the use of the Syncrometer.

Applying Dr. Clark's protocol means having knowledge in many fields.. One must know  how the human body works, the pathogens that invade us, how to detoxify our excretory organs, which supplements and ortho-molecular substances to apply. You need to have some biophysical notions because it means understanding how low voltage works in the human body. Knowing what we need to eat, food allergens, water, teeth, body and home care, etc. This knowledge is applied all together.

These are the treatment methods that Dr. Clark used:


Dr. Clark's approach is very simple and logical. She took people with the same disorder and looked for what these people had in common.

For example, all diabetics had the parasite Eurytrema pancreaticum in the pancreas together with methanol (a solvent).

With this approach she was able to define a disease according to the presence of specific parasites, bacteria, viruses, heavy metals and more.

Dr. Clark invented various devices but the most known is the  zapper.

It was a casual discovery that became world famous for the fact that so many people have had great benefits.

The great success of Clark is the fact that although the obstacles can come from outside as well as from inside the body, they must be removed both on an energetic and physical level, and therefore one needs to work on various fronts.
Obstacles to good health can ultimately be listed in 4 topics:

  • PARASITES - are killed with electricity and Dr. Clark’s parasite cleanse.
  • POLLUTANTS - from the mouth, food and water, must be eliminated.
  • BILIARY AND HEPATIC STONES - are removed with the liver cleanse
  • KIDNEY STONES – dissolve with the kidney cleanse.

The green walnut husk with wormwood and cloves kill more than 120 species of parasites without side effects. Find the parasite cleanse here and the mop-up program for more obstinate parasites such as Ascaris and tapeworms here

Our excretory organs must be cleansed and strengthened so that they perform their work more effectively. Dr. Clark's cleanses involve the kidneys, the intestines and the liver, as well as the blood and the lymph with the zapper.

Our liquids play a fundamental role in cleansing our emunctories (excretory organs), since in addition to bringing nourishment to the organs, these liquids (called humors) also remove waste and toxins, such as glues, crystals, intestinal poisons, endogenous toxins, etc.

If we take into account that these liquid humors sum up to 60% of the total body weight which is about 42 liters, we understand how important it is for our health that these fluids flow and that they are not overburdened and clogged with toxins. Dr. Clark cleanses and the use of the zapper help to do this.

The Kidney cleansing is one of the most important cleanses, because the kidneys are constantly exposed to large concentrations of toxic substances. Our white blood cells need to empty their toxic load into the bladder and then eliminate it via urine. This can only happen if our kidneys are totally clean as they are the previous step on the way to the bladder.

Dr. Clark has carefully chosen herbs and roots, from the "Garden of Nature" to prepare the best kidney recipe to strengthen and cleanse the kidneys. This herbal recipe dissolves kidney stones and removes methyl malonate, heavy metals including gold, dyes, asbestos, radioactivity, wheel bearing grease, motor oil in addition to plastic and rubber. These herbs and roots chosen by Dr. Clark for her kidney cleanse were used by North American Indians as a remedy for kidney and bladder stones. Find her kidney cleanse here.

Today almost no one can say that their intestines are in perfect condition.

Dr. Clark said that bacteria are always at the root of intestinal problems. Salmonella, Shigella, Clostridium and E. Coli are extremely harmful as they have the ability to invade the rest of the body and colonize a traumatized place, a weakened organ.

Many bacteria also come from the liver and end up in the intestine and stomach transported by the bile. If your intestines are weak, it is advisable to cleanse the intestines even before doing the liver cleanse, in order to not overload them with the Liver Flush. Find the Bowel Program here.


The liver, our largest functional organ, performs far more functions than any other organ, and therefore its health is paramount. It contains miles of bile ducts that need to be clean so that they do not clog. The Liver Cleanse is the shortest, least expensive and most effective cleanse. Find the Liver Cleanse page here

The benefits of emptying the bile ducts are manifold:

  • Increased excretion of bile and pancreatic enzymes
  • Proper absorption of calcium and iron
  • Proper digestion, with consequent decrease of bacteria
  • Proper cholesterol and triglyceride levels
  • Cleaner venous blood, with benefits for the whole circulatory system including the heart, lungs and kidneys
  • Best lymphatic function
  • Removal of bacteria, viruses and mycotoxins from the liver
  • No allergies
  • Color and quality of the skin improve
  • Pains disappear
  • Extra boost of energy

HEAVY METALS play a very critical and dangerous role in our health. According to Dr. Clark heavy metals are not made to be placed on our skin, in the mouth, in the food we eat or in the water we drink. There are two sources of heavy metals in our body:

External source

  • Dr Clark found solvents, heavy metals and lanthanides in 90% of the vitamins, minerals, supplements, capsules and pills tested.
  • Up to 50 different metals in dental metal fillings.
  • Up to 20 different metals in water

 Internal source

  • Each enzyme contains a mineral inside
  • Once an enzyme has run out of its life it is digested, but leaves the mineral as a waste, now in the form of METAL.
  • We eliminate it with feces and urine, but fungi and bacteria can find it before we get rid of it.

Metals participate in the deactivation of our white blood cells!

Parasites and bacteria use them to thrive and grow and then expel them. 


  • PCB


Most solvents dissolve fat, and this could endanger our lives, because the lining of our cell membranes is made of fat, especially our nerve cells.

If we have solvents in the body, all the intermediate stages of parasites can develop, which they normally do not. The most dangerous solvent is benzene.



  • Herbal supplements, Minerals, Vitamins
  • Homeography
  • Magnets
  • Infusions

Dr. Clark conducted a unique study on food allergens. A sick organ is strengthened by eliminating its specific food allergen.

Chlorogenic acid, phloridzin, and gallic acid are the corresponding allergens for the hypothalamus, the pituitary and the pancreas. Food allergens can inflame an organ, which means that the cells become permeable, and bacteria and viruses can enter. For more information on food allergens, go here.

Concerning dental health following must be eliminated:

  • Heavy metals, dyes, Clostridium, Radioactivity (Polonium and Uranium)
  • Stop the release of substances from plastic fillings

Water is the most important element. Read more on water here

In about half of the water samples that Dr. Clark  tested contained bleach. Bleach in water can contain:

  • PCB
  • Benzene
  • Malonic acid
  • Isopropyl alcohol
  • Asbestos
  • 20 different heavy metals
  • Dyes
  • Wheelbearing grease
  • Motor oil
  • A high level of radioactivity

Our houses:

At home we can find the following toxins:

  • Arsenic, Cobalt, Nickel, Vanadium, Fiberglass, Vanadium, Freon, Cesium, Formaldehyde, Asbestos, Benzene, etc.

Body care products:

Cosmetics expose women to 175 chemicals daily

This is the title of the Daily Mail article in 2006. The article emphasizes that using 12 products a day exposed women to 175 chemicals.

In body care products, Dr. Clark found:

Stearoyl, Phenoxyethanol, propylene glycol, Barium, PCB, Benzene, etc.

A good body product should NOT contain:

Synthetic ingredients, artificial preservatives, artificial colors, artificial flavors, petroleum products, coal tar derivatives, genetically modified ingredients.

Dr. Clark has written 8 books, of which 6 are on cancer. In these books, she describes her methods, results and conclusions.

She never sold products, but rather just wanted the public to acquire her knowledge.
