Dr. Hulda Clark and the question of what actually makes us sick
Throughout her life, the biologist and physiologist Dr. Hulda Regehr Clark investigated the question of what actually makes people ill. In the course of her research, she took the view that environmental toxins and parasites were the cause of serious and most severe illnesses in humans. Parasites, which accumulate in almost every human organism, would be in the most diverse stages of development and would form disease patterns accordingly. Particularly due to the high hygienic standards of the western world, this thesis seems absurd at first. However, parasites do in fact play a decisive role in the development of diseases, which is why the so-called Clark method is becoming increasingly important in local alternative medicine. In the following article you will learn what it is all about.
What are parasites?
The term "parasite" comes from the Greek. While "para" can be translated as "next to", "sitos" means "food". In concrete terms, the word "parasite" refers to an organism that has taken up residence in another, larger organism and obtains its nourishment from it. The size of the parasite can vary greatly, ranging from a single-celled organism (protozoan) to a metre-long tapeworm. Clark estimates that up to 130 species of parasites can nest in humans.
Where do parasites nest most frequently and what symptoms can they cause?
Many parasites nest in the human digestive tract in particular, but also in the blood and lymphatic systems. Intestinal parasites can cause irritation in the intestines, flatulence, but also diarrhoea and/or constipation. In general, patients suffering from a parasite infestation may complain of listlessness, fatigue and/or lack of concentration. This is due to the fact that the parasites deprive the host, i.e. the human being, of important vital substances and thus energy.
In addition to the intestinal area, parasites can also be found particularly frequently in the connective tissue, joints or muscles. But parasite infestations are even possible in the brain and other organs. Parasites that have taken up residence in the organs can form cysts there and cause inflammation.
Worm treatment out of fashion today, but once medical practice
Until the end of the Second World War, it was common practice in Germany for people to undergo regular worming treatment. So you could not only buy a so-called worming medicine in every corner shop. It was also common knowledge that regular worming treatments were beneficial to health. With the advent and hype of antibiotics, the healing knowledge of worming disappeared from social consciousness and is nowadays only administered by veterinarians to four-legged friends. Yet a worming cure would also be beneficial for humans. Although the hygienic conditions of our environment have improved greatly, we are still exposed to chemicals on a daily basis. Clark is certain that various environmental toxins and solvents in particular play a decisive role in parasites entering the human body. The immune system is so overstrained by them that it can no longer fight off the parasites. We encounter solvents in particular everywhere in everyday life, whether in the form of washing-up liquids, shampoos or cosmetics. According to Clark, if the parasite infestation is due to the presence of solvents, the parasites can pass through all the developmental stages in the human organism and thus trigger particularly serious diseases.
How do parasites get into the human body?
The occasional consumption of worm eggs is virtually unavoidable for humans. In the process, the worm eggs are distributed in the human body through the intestinal mucosa. While some of the eggs are excreted again, some worm eggs are transported through the intestinal wall into other organs. Normally, they are destroyed here by the so-called phagocytes in the blood. It is therefore normal that humans have always acted as intermediate hosts for parasite eggs.
How does man become ill according to Hulda Clark?
Clark assumes that human contact with solvents leads to the detachment of the skin of the worm eggs. The detachment of the skin of the worm eggs starts the development of the larvae, which means that the immune system is not only dealing with an egg, but with a larva that is about to develop into a real worm. Thus, humans no longer act as intermediate hosts for parasite eggs, but rather become hosts for parasites.
A parasitic infectious disease, a so-called parasitosis, can manifest itself, for example, as a skin rash, joint complaints, asthma or diarrhoea. The symptoms are not identical in every patient, because a parasitosis develops where the organism has its particular weak point. This is different for each person, so that parasitoses can produce a wide variety of clinical pictures.
How can parasitosis be diagnosed and treated?
The diagnosis of parasitosis is anything but simple. Often, stool diagnostics are carried out, but they do not necessarily always detect parasites. Even if the stool is worm-free, this does not mean that there are no worms in the body. According to Clark, most worms reside in the upper intestine and are digested before being excreted.
To treat intestinal parasites, Clark therefore suggests a herbal cure consisting of herbal products such as cloves, wormwood and black walnut tincture. In addition, however, Clark has also developed a frequency therapy with which the shell surrounding the parasites is to be made to vibrate. This vibration irritates the parasites and the immune system is supported in fighting the parasites.
What does the therapy concept according to Dr. Clark consist of?
The Clark therapy is based on the following four cures or cleanses, which are to be understood as acute medicine and should contribute to the immediate recovery of the patient:
- 1. a parasite cure
- 2. a liver cleanse
- 3. a kidney cleanse
- 4. an intestinal cure
Since the cures do not permanently eliminate the causes of the disease, the following five remedies must be carried out afterwards. The remedial measures should help to permanently banish toxins, parasites and bacteria from the patient's life.
- 1. the remediation of the dentition
- 2. remediation of the diet
- 3. sanitation of the body
- 4. the rehabilitation of the living space
- 5. the rehabilitation of the body's own water
There is no scientifically valid evidence for the therapy concept according to Dr. Clark regarding its effect and effectiveness. For this reason, the treatment methods are not recognised by evidence-based medicine. In any case, they are to be regarded as alternative healing methods.
Treatment methods against cancer according to Dr. Clark
Dr. Clark did not only research in the field of parasites. She also dealt with bacteria, fungi and viruses, up to heavy metals, radioactivity and solvents. She also dealt extensively with all aspects of cancer and developed effective treatment methods against it in the course of her research work. In many patients she succeeded in stopping the growth of metastases within 24 hours. To do this, she used a treatment device called a zapper and a testing device called a syncrometer. But what exactly is her method?
There are many causes of cancer. Dr. Clark has identified some causes which are of great importance for the development of cancer.
- Parasites in various stages of development: here the human intestinal fluke (Fasciolopsis buski) is of particular importance, which can be transmitted to humans through the consumption of certain aquatic plants.
- Toxins: the solvent isopropyl alcohol is of particular importance here. In order to eliminate the toxins from the body, Dr. Clark suggests a holistic rehabilitation, which should prevent the absorption of further toxins into the human body. In addition to dental remediation, i.e. the removal of all harmful materials from the dentition, including dental materials containing mercury, the patient's working and living environment should also be looked at more closely, if possible by a building biologist. In addition, Dr. Clark advises the patient to use only organic body care products and to avoid additives in their diet.
- lack of the body's own immune defence system
Clark concludes from this causal research that parasites, the absorption of toxins and also the detoxification organs as well as immunity are immensely important in the development of cancer. Therefore, cancer can only be treated with a holistic therapy. Conventional treatment methods, for example the surgical removal of the tumour, only attack one point and therefore cannot cure the cancer conclusively, as the cause of the cancer is not eliminated. Dr. Clark's treatment method therefore starts by eliminating the cause before beginning with the actual therapy. And this in turn consists of phytotherapeutic and orthomolecular measures, which can be combined with the frequency therapy she developed. Especially the so-called zapper according to Clark is used here.
The zapper according to Clark
The so-called zapper according to Clark is a battery-operated electrical stimulator which administers a weak alternating voltage to the patient's tissue or neighbouring vessels via two main electrodes. In this way, parasites, bacteria or viruses are made to vibrate and thus be damaged. However, the effectiveness of the zapper method has not been confirmed. in 2003, Dr. Clark was even prohibited by a court from making health-related advertising for the zapper.
Hulda Clark's frequencies from 'The Cure for All Diseases'.
Note: three additional frequencies have been added to this list, with a " ** " before the entry for "Adenovirus"; recently it has been found that some cold-like symptoms do not respond to the use of the 393kHz, which was so often the solution in the past. These primary frequencies were detected by Hulda Clark in her research.
To relate these to "Rife frequencies", which are limited to much lower frequencies in the audio range due to the technical limitations of the equipment, or to translate these higher frequencies into a frequency that can be set on EMEM2, EMEM2+ or Rife/Bare Plasma systems, divide the Clark frequency found here by 512.

Tapeworms
Tapeworms are segmented. The first segment is the head, called the scolex. Tapeworms grow by adding a new segment to their body. Tapeworms can have very large bandwidths (frequency range) that vary depending on the length of the specimen! It is as if each new segment has a unique and slightly lower frequency. Do not use a frequency generator to kill tapeworms. If you accidentally kill middle segments instead of working your way up from the bottom, you may end up with a scatter! Use only one zapper.
(Note: By this Hulda meant only use a device that produces a pulsed DC square wave output).
