The History of Frequency Therapy

Before 'frequency therapy': from electric fish to Galvani and Volta

Experiments with electric phenomena for healing are much older than modern electrical engineering. Ancient sources mention the use of electric fish, and later in the 18th century, physicians and naturalists tested static electricity and Leyden jars. However, a decisive step came with Luigi Galvani (1737–1798).

Galvani observed muscle contractions in frog legs during electrical stimulation and developed the idea of 'animal electricity.' His explanation was not entirely accurate in all details, but it opened a new field. The dispute with Alessandro Volta (1745–1827), who emphasized the role of metals and later developed the voltaic pile, did not hinder development — on the contrary. From this dispute, both electrophysiology and the development of reliable electrical sources emerged.

Why is Galvani important in the history of frequency therapy?

Not because he used today's frequency protocols. His significance is deeper: he showed that biological tissue responds to electrical energy. This is the foundation on which later researchers could begin to ask whether the response could be modified by the strength, polarity, duration of the pulse, waveform shape, and ultimately also by frequency.

In the 19th century, Guillaume-Benjamin-Amand Duchenne de Boulogne systematically used electrical stimulation in the study of nerves and muscles. Using surface electrodes, he mapped muscle function and contributed to the development of electrodiagnostics and electrotherapy. From this point on, electricity in medicine was no longer an unusual experiment, but became a measurable tool of physiology.

From current to field: Faraday, Maxwell, Hertz, d'Arsonval, and Tesla

The next major step did not come from medicine, but from physics. Michael Faraday (1791–1867) showed through electromagnetic induction that a changing magnetic field can produce an electric effect. His intuitive view of 'lines of force' was later mathematically connected by James Clerk Maxwell (1831–1879).

Maxwell unified electricity and magnetism into a single theory in the second half of the 19th century. His equations showed that changing electric and magnetic fields are interrelated and that electromagnetic waves can propagate through space. Heinrich Hertz then experimentally confirmed Maxwell's prediction of electromagnetic waves.

Arsène d’Arsonval: High Frequencies in the Medical Laboratory

The French physiologist and physicist Jacques-Arsène d’Arsonval (1851–1940) studied the physiological effects of high-frequency currents at the end of the 19th century. The term d’Arsonvalization originated from him. His work is important because the focus shifts from the simple direct current to alternating currents with higher frequencies and their effects on the body.

Nikola Tesla: High-Frequency Oscillations and Electrotherapeutic Possibilities

Nikola Tesla (1856–1943) very early on in his research on high-frequency alternating currents noticed that their effect on the body differs from that of low-frequency current. In 1898, he published an article titled High Frequency Oscillators for Electro-therapeutic and Other Purposes, in which he described various ways of using high-frequency oscillators and explicitly warned that it would be good if physicians also systematically researched the specific physiological effects.

This is a very important historical point. Concepts that repeatedly appear in later frequency therapy come to the forefront: oscillation, frequency, resonant circuits, electromagnetic field, contactless transmission, and various ways of connecting energy with the body.

Georges Lakhovsky: the cell as an oscillating system and Multiple Wave Oscillator

One of the most interesting early authors who directly connected biology with resonance was Georges Lakhovsky (1869–1942), a Russian-French engineer and inventor. His fundamental idea was that it might be possible to consider cells as small electrical or electromagnetic oscillators, and that their state could be related to their own oscillations. In 1931, he filed an American patent application, and patent US 1,962,565 was granted in 1934 for the device Apparatus with circuits oscillating under multiple wave lengths.

The device used several concentric open loops of different diameters. The purpose of the design was to create electromagnetic fields with multiple wavelengths or a wide range of oscillations. In later literature, this approach became known as Multiple Wave Oscillator (MWO).

What was new about Lakhovsky's approach?

• he did not think about just one current or one frequency, but about a multitude of oscillations and harmonics;
• he placed resonance in the foreground as a possible principle of interaction between the field and biology;
• he used a high-frequency electromagnetic field, not just a contact current;
• he documented the technical design with a patent, so today we can clearly see what he actually constructed.

Royal Raymond Rife: microscopy, resonance and the most famous story of frequency therapy

If there is a name that is today almost synonymous with alternative frequency therapy, it is Royal Raymond Rife (1888–1971). Around him, over the years, a mixture of documented history, technical achievements, later testimonies, controversial interpretations, and legends has woven itself. Therefore, with Rife it is especially important to distinguish what can be verified from what remains historically unproven.

Rife as a microscope constructor

Rife developed complex optical instruments and collaborated with bacteriologist Arthur Isaac Kendall. In 1931, Kendall and Rife published an article titled Observations on Bacillus Typhosus in Its Filterable State in the journal California and Western Medicine. Rife's microscopy was later also discussed in the article The New Microscopes in the Journal of the Franklin Institute in 1944.

This part of the story is important because Rife was not only a later icon of alternative medicine. He dealt with an actual technical problem: how to improve the observation of very small structures and living samples. His microscope technology attracted enough interest in its time to be written about even in professional literature.

»Mortal Oscillatory Rate« – Rife's central idea

Rife researched the characteristic oscillatory or resonant properties of microorganisms. He investigated whether particular frequencies could selectively weaken or destroy individual microorganisms. The term Mortal Oscillatory Rate (MOR) became associated with this idea. This very idea later became the basis for numerous »Rife« devices and frequency lists.

A notable story from 1934

An important part of Rife's legacy is the story that began in the summer of 1934, when his work first crossed the threshold of the laboratory. Doctor Milbank Johnson organized a multi-month clinic in La Jolla, in which Rife's frequency instrument was tested on a group of seriously ill people. Later accounts speak of results that made 1934 almost a legendary chapter in the history of frequency therapy.

The real story, however, is somewhat more complicated and therefore also interesting. The clinic actually existed, and there are letters and testimonies from doctors about it. Unfortunately, the complete clinical records have not survived, so today we cannot confirm with certainty the often-repeated story of '16 cancer patients cured.'

We can, however, say something else: Rife's ideas were interesting enough at the time for doctors to want to test them on humans. Therefore, in 1934, Rife and some laypeople were not the only ones experimenting. Around him were doctors, laboratory researchers, and people like Milbank Johnson and Arthur Kendall, who took his work seriously enough to want to test and document it.

Lab notebooks from 1933–1934 also exist regarding Rife's work with tumors and so-called »BX virus«. Rife believed he had found an important connection between this and the development of cancer, although his conviction regarding a universal cause of cancer is not accepted in oncology today. Nevertheless, it was precisely the experiment from 1934 that became an event which caused Rife's name to still generate interest, discussions, and a desire to re-examine his ideas almost a century later.

From Antoine Prioré to Robert O. Becker: when bioelectricity enters established biomedical research

Antoine Prioré and the French »Prioré affair«

In France, Antoine Prioré (1912–1983) attracted attention in the 1960s and 1970s. He developed large electromagnetic devices with which he conducted experiments and claimed that they could influence the course of various diseases, including tumors. His work received support from some prominent scientists and public funding, but it also sparked one of the more unusual scientific controversies in post-war France.

The problem was primarily one of reproducibility and transparency: Prioré did not clearly disclose his system, the devices were complex, and explanations of the mechanism were controversial. Because of this, his results did not become standard therapy. However, the story shows something important: the biological effects of complex electromagnetic fields were interesting enough for laboratories, academics, and state institutions to take them seriously.

Robert O. Becker: do not confuse him with Bob Beck

Robert O. Becker (1923–2008) was an American orthopedic surgeon and researcher in bioelectricity. His name is similar to that of Bob Beck, but it refers to a completely different person and a different research tradition.

Becker studied electrical phenomena in bone regeneration and healing. In 1977, he and his colleagues published clinical experiences with low-intensity direct current in non-healing fractures. His work is part of a broader field in which researchers have shown that bone has measurable bioelectric properties and that the healing process can be stimulated in some circumstances by controlled electrical stimulation.

C. Andrew Bassett and Arthur Pilla: pulsed electromagnetic fields

C. Andrew Bassett, Robert J. Pawluk, and Arthur A. Pilla systematically developed the use of pulsed electromagnetic fields (PEMF) in bone healing during the 1970s. In 1974, they published a paper in the journal Science about accelerating bone repair using inductively coupled electromagnetic fields.

This is one of the most important points in the entire history. Here, the broad idea that 'an electromagnetic field can influence a biological process' moves from pioneering and often controversial experiments into standardized biomedical research, measurable parameters, and clinical application.

Bob Beck and Hulda Clark: frequency devices move from laboratories into everyday use

In the 1990s, a different shift occurred. Devices were not only becoming more technically refined, but also smaller, cheaper, and more accessible. It was precisely during this period that Robert C. 'Bob' Beck and Hulda Regehr Clark had a significant influence.

Bob Beck and the idea of 'blood electrification'

Bob Beck popularized the idea of using very small electrical impulses through wrist electrodes in the early 1990s. He referred to laboratory work associated with Steven Kaali and Peter Schwolsky. Kaali and Schwolsky filed a patent in 1990 for the processing of blood or other conductive fluids using electrical forces, and there were also laboratory reports on the effect of electric current on the infectivity of HIV in vitro.

In this story, the key technical difference is: the patent described the electrical processing of blood or fluid in a conductive system, and there is no evidence that the transcutaneous use of wrist electrodes is biologically equivalent. Beck's implementation was his own practical expansion of the idea. The clinical effectiveness of his entire protocol has not been confirmed in a manner comparable to approved medical devices.

Despite this, Bob Beck has had a significant historical impact. He presented frequency and pulse devices as something that could be small, personal, and accessible, not just as large laboratory equipment. This strongly shaped the later culture of home frequency devices.

Hulda Clark and the zapper

Hulda Regehr Clark (1928–2009) popularized the simple concept of the zapper, particularly in the 1990s through her book The Cure for All Diseases: a low-voltage device that creates a pulsed signal and is used with contact electrodes. Her writings connected various diseases with parasites, microorganisms, and environmental toxins and included numerous assigned frequencies.

Clark had an exceptional influence on the popularization of frequency devices, especially because she transformed the complex topic into something people could understand, assemble, and use at home.

Anthony Holland: modern return to resonance and frequency selectivity

Anthony Holland, a long-time professor of music and director of electronic music laboratories at Skidmore College, became known in the 21st century for experimental research into the possibility that oscillating fields at specific frequencies could affect cancer cells. His interest grew at the intersection of acoustics, electronics, plasma systems, and biology.

The broader public knows him mainly for his lecture Shattering Cancer with Resonant Frequencies. In laboratory experiments, he and his team researched oscillating pulsed electric fields created by a plasma source and monitored the response of various cell cultures.

The research question is interesting precisely because it returns to a theme that followed Lakhovsky and Rife: is it possible to find frequency ranges at which a particular type of cell responds especially strongly?

When electric field therapy enters mainstream medicine

The strongest argument for the broader idea of frequency biology is not the claim that all historical pioneers had everything exactly right in all details. A stronger argument is the fact that today there are approved medical therapies in which electric or electromagnetic parameters are an active part of the treatment.

Electrical stimulation and PEMF in bone

Electrical stimulation and pulsed electromagnetic fields have a long clinical history in the context of specific bone healing issues. Research has shown that the biological response depends on the mode of stimulation and the dose, with electrical parameters and frequency also being important. This is a clear example that the field is not merely an accompanying phenomenon, but can represent a therapeutic stimulus.

Tumor Treating Fields (TTFields)

A particularly interesting modern example is Tumor Treating Fields, or TTFields. These are low-intensity alternating electric fields in the range of approximately 100–300 kHz, delivered through electrode arrays on the skin. Their purpose is to influence processes in dividing tumor cells, especially the mitotic apparatus and the arrangement of polar molecules during cell division.

TTFields are not a theory from alternative literature, but a regulated medical technology tested in clinical trials. The American FDA has approved the technology for certain oncological indications, including glioblastoma, mesothelioma, and metastatic non-small cell lung cancer; in February 2026, the FDA also approved the Optune Pax system for certain patients with locally advanced pancreatic cancer in combination with chemotherapy.

Frequency-modulated radiofrequency fields

There is also a modern research line connected to Boris Pasche, Alexandre Barbault, and their colleagues, which investigates radiofrequency electromagnetic fields amplitude-modulated with very low, tumor-associated frequencies. Clinical observations and laboratory experiments have been published; however, the field is still under research and should not be equated with the already standardized indications for TTFields.

What does the history of frequency therapy really tell us?

If we look at all this history without prejudice — neither with automatic enthusiasm nor with automatic rejection — we get a surprisingly clear picture. The idea of the influence of electricity, electromagnetic fields, and frequency on biology did not appear once and then disappear. In various forms, it has returned for more than two centuries.

1. Bioelectricity is the basis of biology

Cell membrane electric potentials, nerve action potentials, electrically induced muscle contraction, and heart rhythm are fundamental physiological phenomena. A living organism is not electrically passive.

2. Frequency can change the mode of interaction

With alternating currents and fields, it matters whether we are talking about a few hertz, kilohertz, or megahertz. Tissues have frequency-dependent impedance and dielectric properties, and different systems use different ways of energy coupling.

3. Some historical pioneers were ahead of the evidence, not necessarily ahead of the questions

Lakhovsky, Rife, Priore, Beck, and Clark often provided explanations and therapeutic claims that exceeded the evidentiary level of their time. However, this does not mean that the question of the biological effects of frequency-specific fields was nonsensical. On the contrary: part of this broader research question is now being studied with significantly better instruments and methods.

4. Today we can distinguish between three levels

That is why the history of this field is so interesting. It connects Galvani's frog, Maxwell's equations, Tesla's high-frequency oscillators, Lakhovsky's rings, Rife's microscopes, Becker's bioelectricity, Bassett's pulsed fields, the home zappers of the 1990s, and today's sophisticated oncological systems. These devices are not the same and their evidence is not the same. However, they share the idea that biology can also be studied through the language of electricity, fields, oscillations, and frequencies.

Continue exploring frequency therapy

History shows where the ideas came from. The next step is to understand how individual methods of frequency transmission differ in practice: contact electrodes, pulsating electromagnetic fields, plasma transmitters, carrier waves, harmonics, and various frequency generators are not the same thing.
