About Hulda Clark

Hulda Regehr Clark was born on October 18, 1928 in Rosthern, Saskatchewan, Canada. She began her studies in Biology at the University of Saskatchewan, where she was awarded a Bachelor of Arts, Magna Cum Laude in 1950 and later on a Masters degree with High Honors. In 1958, the University of Minnesota awarded her a Doctorate degree in Physiology. Dr. Clark's studies focused on Biophysics and Cell Physiology.

Dr. Clark established a nutritional consulting practice in the 1960's as a complement to her research at University of Indiana. When federal research funds were eliminated in 1974, she concentrated on her private nutritional consulting practice. She obtained a naturopathy degree from the Clayton College of Natural Health.

Dr. Clark's independent research brought her to studying the relationship between microorganisms such as parasites, bacteria, and viruses, and pollutants such as heavy metals, solvents, and radioactivity, in the context of its effects on the human body in the form of diseases, especially cancer.

Dr. Clark researched the use of herbs, essential oils, orthomolecular therapy, and frequency therapy to treat diseases. She emphasized the importance of dental health, as well as an increased awareness of environmental pollution.

Hulda Clark's most important discovery was the zapper, a handheld battery operated device that Dr. Clark claimed to electrocute pathogens using a positive offset 30 kHz square wave frequency. She also invented the Syncrometer, an audio oscillator circuit that Dr. Clark used to detect resonance in matter and substances. Dr. Clark published many experiments using the Syncrometer to scan the human body for the presence of parasites and pollutants. She also used the Syncrometer to test whether products were contaminated with parasites and/or pollutants. Hulda Clark published these experiments in her books.

Dr. Hulda Clark wrote 7 books, "The Cure For All Cancers," "The Cure For All Diseases," "The Cure For HIV and AIDS," "The Cure For All Advanced Cancers," "The Prevention of All Cancers," "Syncrometer Science Laboratory Manual," and "The Cure and Prevention of All Cancers" published in 2008.

Hulda Clark endured many attacks by professional adversaries, including legal battles which were eventually dismissed by courts. Despite the setbacks, Dr. Clark persisted in her research and in sharing her knowledge with the world through her books and lectures all over the world.

Hulda Clark died in her sleep on September 3, 2009. She was 80 years old. The initial statement released regarding her death was that she had arthritis and a spinal cord injury. The death certificate released a month later states she died of anemia and hypercalcemia. Without a biopsy, her doctors also diagnosed her with multiple myeloma, which is cancer of the plasma cells in the bone marrow, a bit of information that Dr. Clark's adversaries gloat over in their continuing attack of her life's work.

Dr. Hulda Clark's research proved that cancer is caused by a combination of parasites and pollutants. Her advice for preventing cancer was to avoid parasite infection and eliminate contact with toxic chemical pollutants. By working directly with cancer patients, Dr. Clark exposed herself everyday to the very things that she advised everyone else to avoid. In the end, she sacrificed her own life for the furtherance of her research.

Dr. Hulda Clark knew she was at the beginning of an exciting new development in science, with room for discovery and improvement. She invited others to take her research and experiments further. This was Hulda Clark's Gift to Humanity.


Many websites state that they are the "Official" Hulda Clark website. But did you know that Dr. Hulda Clark never manufactured any zapper or herbs? Dr. Clark only published books. Her son Geoff Clark founded Self Health Resource Center and produced the original SyncroZap zappers, Clark family brands that have since been sold to other merchants.

The only website Hulda Clark ever had a hand in creating was, in which she wrote a holiday greeting each year to her readers. Like all the other Clark-related sites, is not affiliated with Hulda Clark's estate.

It all comes down to the laws governing Free Speech in the United States. Dr. Clark wrote books with controversial titles, such as The Cure For All Cancers, and The Cure For HIV and AIDS. Because of free speech, it is within her right to do so. However, if Dr. Clark ever sold any of the items described in her books, the content of her books would become product claims and would no longer be considered free speech. If Dr. Clark manufactured zappers and then claimed that zappers cured disease she would have had to prove that claim to the Federal Trade Commission and the Food and Drug Administration. To do a 10-year double-blind study on a medical device starts at $600 million dollars and up. There was no way for Hulda Clark to afford studies that cost so much.

Hulda Clark published several self-health books in her lifetime. She considered them her Gift to Humanity. Read and get well.
