Hulda Regehr Clark

Hulda Regehr Clark (18 October 1928 in Rosthern, Saskatchewan – 3 September 2009 in Chula Vista, California) was a Canadian naturopath, author, and practitioner of alternative medicine.

Clark claimed all human disease was related to parasitic infection, and also claimed to be able to cure all diseases, including cancer and HIV/AIDS, by "zapping" them with electrical devices which she marketed.

Clark wrote several books describing her methods and operated clinics in the United States.

Following a string of lawsuits and eventual action by the Federal Trade Commission, she relocated to Tijuana, Mexico, where she ran the Century Nutrition clinic.

Clark's claims and devices have been dismissed by authorities, ranging from the United States Federal Trade Commission and Food and Drug Administration to CAM figures such as Andrew Weil, as scientifically unfounded, "bizarre", and potentially fraudulent.

Her own biographical sketch states her degree was in physiology, but the Graduate School's Register of Ph.D. Degrees conferred by the University of Minnesota, July 1956 – June 1966, states she received a Ph.D. in Zoology in 1958.

Her thesis was entitled ''A Study of the Ion Balance of Crayfish Muscle: evidence for two compartments of cellular potassium.

''

She received her doctorate degree in 1958 from the University of Minnesota.

In 1979, Clark left government-funded research and began private consulting and her own research.

In 1993, while Clark lived and practiced in Indiana, a former patient complained to the Indiana attorney general.

An investigator for the Indiana Department of Health and a deputy attorney general visited her office incognito as part of a sting operation.

Clark proceeded to test the investigator and "told him he had the HIV virus [sic], but said that he did not have cancer."

She told the investigator that she could cure his HIV in three minutes, but that he would "get it back" unless he committed to returning for six more appointments.

She then ordered blood tests from a laboratory.

Unknown to the investigators, Clark learned of the undercover investigators' status.

She then stated everything she had told them had been a "mistake".

Two days later, before an arrest warrant could be served, she had vacated the premises and disappeared.

Six years later, in September 1999, Clark was located and arrested in San Diego, California, based on a fugitive warrant from Indiana.

According to Clark, this was the first time she learned about the charge.

Her lawyer protested the long delay before her arrest, but a prosecutor implied that she fled Indiana "when she learned that she was being investigated by the state," and the local police department had limited resources to devote to finding her.

She was returned to Indiana to stand trial, where she was charged with practicing medicine without a license.

From 2002 until her death she operated the Century Nutrition health clinic in Tijuana, Mexico, where her focus was primarily on late-stage cancer patients.

Clark and her son Geoff separately owned businesses her patients and others used, including a restaurant, her self-publishing company, and a "self-health" store that sold her inventions.

She published several books, including The Cure of All Cancers, The Cure for HIV/AIDS and The Cure For All Diseases.

According to civil court records, her books generated over $7 million in sales by 2002, although Clark disputed this figure.

She held a naturopathy degree from the non-accredited and defunct Clayton College of Natural Health a school lacking accreditation from any accreditation agency recognized by the United States Department of Education.

According to Clark, all disease is caused by foreign organisms and pollutants that damage the immune system.

She asserted that eliminating these organisms from the body using herbal or electrical means while removing pollutants from the diet would cure all diseases.

In her book The Cure For All Cancers, Clark postulated all cancers and many other diseases are caused by the flatworm Fasciolopsis buski.

"The adult [fluke], though, stays tightly stuck to our intestine or liver, causing cancer, or uterus, causing endometriosis, or thymus, causing AIDS, or kidney, causing Hodgkin's disease)." "I have found that cancer, HIV, diabetes, endometriosis, Hodgkin's disease, Alzheimer's disease, lupus, MS and "universal allergy syndrome" are examples of fluke disease." However, this worm does not live in the United States or Europe, but mainly in India, parts of China, Vietnam and other east-Asian countries, and only in rural areas where people are eating unboiled food from water plants, or where pigs live close to humans. According to Clark, depression is caused by hookworms. Epilepsy and seizures are caused by swelling in the brain, attracting calcium and heavy metals, The swelling being caused by parasites of the genus Ascaris as well as by malvin, a natural dye found in strawberries, chicken, and eggs.

Clark claimed she could cure all diseases, whereas, she asserted, conventional treatments for diseases, such as cancer and HIV/AIDS, often only aim to relieve symptoms.

She was described in the book Denying AIDS as "perhaps the first quack AIDS curer".

David Amrein's website contains a disclaimer stating that her treatments are "not prescribed as treatment for medical or psychological conditions" and "...the treatments outlined herein are not intended to be a replacement or substitute for other forms of conventional medical treatment."

Nonetheless, Clark advocated for the use of her methods as a substitute for standard medical care:

"Does this mean you can cancel your date for surgery, radiation or chemotherapy? YES! After curing your cancer with this recipe it cannot come back ... Remember that oncologists are kind, sensitive, compassionate people. They want the best for you. They have no way of knowing about the true cause and cure of cancer since it has not been published for them."

Regarding the effectiveness of her treatment, Clark wrote, "The method is 100% effective in stopping cancer regardless of the type of cancer or how terminal it may be. It follows that this method must work for you, too, if you are able to carry out the instructions."

Clark died 3 September 2009 from blood and bone cancer.

Clark began her studies in biology at the University of Saskatchewan, Canada, where she was awarded Bachelor of Arts and Master of Arts degrees.

After two years of study at McGill University, she attended the University of Minnesota studying biophysics and cell physiology.
