Science: Bioelectricity

What It Is

Bioelectricity is the study of the voltages living tissue generates and uses. Every cell, not only nerve and muscle, holds a voltage across its membrane, maintained by ion pumps and channels. This is textbook cell biology and it is not disputed. The research question is the next step: slow voltage patterns across ordinary cells appear to carry information about what a tissue should build. The subject has three parts, kept separate here: what is established, what is at the frontier, and what is sold in the same words but fails testing.

The Established Science

The membrane voltage is the foundation. Cells run from around minus 10 millivolts in rapidly dividing and cancerous cells to about minus 90 in mature, fully differentiated ones. That spread tracks a distinction: cells that have not yet differentiated sit depolarized, and cells that have finished sit polarized. This is the observation the modern bioelectric research program is built on.

In frog embryos, changing the bioelectric state of cells produced complete eyes in the wrong place. Changing the bioelectric pattern in a flatworm produced a two-headed animal without any change to its genome. These experiments are replicated and published in mainstream journals. A voltage change alone produced the new structure, so these patterns carry instructions for large-scale form.

Two funding notes belong with those results. Michael Levin, whose lab produced the frog-eye and two-headed-flatworm work, co-founded Morphoceuticals, a company developing bioelectric therapies. Richard Nuccitelli, who measured the human wound field described below, took those measurements with a device from his company BioElectroMed. Both bodies of work are published and independently cited; the commercial ties are stated here alongside them.

A cut generates a direct-current field at its edge, measured in human skin at about 107 to 148 millivolts per millimeter in young adults and running roughly a third weaker in people over 65. In cell culture and in mice, an applied field of similar strength outcompetes chemical and contact cues and becomes the dominant signal steering where cells move. The human data show the field is present and measurable; the steering mechanism is shown in cells and mice, not in intact people.

Loading bone generates electric potentials at the strained tissue, tied to collagen's piezoelectricity and to fluid moving through the bone. These stress-generated potentials change how bone cells divide and lay down matrix, one route by which bone builds where it is loaded. The piezoelectric effect was demonstrated in the 1950s and is not in question. Its precise role in everyday remodeling, and the value of the electrical stimulation devices that grew from it, are still being sorted out.

How it works

Every cell holds a voltage across its membrane, from about minus 10 to minus 90 millivoltsEstablished

In plain terms

Cells generally, not only nerve and muscle, hold a voltage across their membrane, maintained by ion pumps and channels. Values run from around minus 10 millivolts in rapidly dividing and cancerous cells to about minus 90 in mature, fully differentiated ones.

In detail

Cells generally, not only nerve and muscle, hold a voltage across their membrane, maintained by ion pumps and channels. Values run from around minus 10 millivolts in rapidly dividing and cancerous cells to about minus 90 in mature, fully differentiated ones. Measured in: Universal in biology. The spread matters more than the numbers. Cells that have not yet differentiated sit depolarized, and cells that have finished sit polarized, which is the observation the whole bioelectric research program is built on.

Who this may not transfer to:A property of cells across biology rather than a finding in one group of people, so it applies universally.

A wound generates an electric field of about 107 to 148 millivolts per millimeter that guides healing cellsEstablished

In plain terms

A cut generates a direct-current field at the wound edge, measured at about 107 to 148 millivolts per millimeter in the skin of young adults, and weakening as it heals. In cell culture and in mice, an applied field of similar strength acts as the dominant directional cue and overrides others.

In detail

Nuccitelli and colleagues (2011) measured the lateral electric field at fresh skin wounds and found roughly 107 to 148 mV/mm in adults aged 18 to 25, weakening as the wound healed and smaller in older skin; a comparable field of about 122 mV/mm was measured in mice. In cell-culture and mouse work (Zhao 2006), an applied field of similar strength steered cell migration more strongly than chemical or contact cues, acting through PI3K-gamma and PTEN. The human data establish that the wound field is real and measurable; the directional-cue mechanism is shown in cells and mice rather than in intact people.

Who this may not transfer to:The wound field was measured in adults aged 18 to 80 with the sex not reported, and it runs about a third weaker in people over 65 than in those under 25. The directional-cue mechanism is shown in cells and mice rather than in intact people.

Acupuncture points map about 80% onto connective-tissue planes, a proposed physical mechanismEstablished

In plain terms

Langevin and colleagues proposed that rotating a needle winds connective tissue around it and transmits a mechanical signal to fibroblasts, and that this coupling produces the resistance practitioners call needle grasp. Separately, they mapped an 80% correspondence between acupuncture point locations and connective tissue planes in serial sections of the human arm.

Separately, they mapped an 80% correspondence between acupuncture point locations and connective tissue planes in serial sections of the human arm. Measured in: A hypothesis paper drawing on the authors' human and rat work, plus a cadaveric mapping study of the arm. The mechanism paper is framed by its authors as a hypothesis rather than a demonstration, and the 80% correspondence is an anatomical correlation in cadaver sections, not evidence of a functional channel. It is a testable physical account of needling that does not require meridians to be conduits.

Who this may not transfer to:The 80% figure comes from postmortem sections of the human arm with sex not reported, and it is an anatomical mapping rather than a test in living, treated people.

Bone generates an electric signal under load, part of how it remodels where it is stressedEstablished

In plain terms

Loading bone generates electric potentials at the strained tissue, an effect tied to collagen's piezoelectricity and to fluid movement through bone. These stress-generated potentials alter cell proliferation and matrix production, which is one proposed route by which bone builds where it is loaded. Electrical stimulation devices grew out of this and have been used to help stubborn fractures knit.

These stress-generated potentials alter cell proliferation and matrix production, which is one proposed route by which bone builds where it is loaded. Electrical stimulation devices grew out of this and have been used to help stubborn fractures knit. Measured in: Review of laboratory, animal and device studies of bone bioelectricity. The piezoelectric effect of loaded bone is well established, but its exact role in everyday remodeling and the clinical value of electrical stimulation are still debated, with the review noting uneven trial design and dosing. This card grades the mechanism, not any stimulation product.

Who this may not transfer to:The piezoelectric effect is a material property of bone tissue; the therapeutic stimulation devices are a separate clinical claim that this page does not grade.

Structured or hexagonal water, as sold, is not supportedDebunked

In plain terms

The exclusion zone near strongly hydrophilic surfaces, a layer that repels microspheres, is real and has been independently demonstrated by several groups. What is contested is the explanation: Schurr's diffusiophoresis account competes with Pollack's idea that the water there is structurally different from bulk water, and the reviewers judge the diffusiophoresis explanation the more compelling one.

What is contested is the explanation: Schurr's diffusiophoresis account competes with Pollack's idea that the water there is structurally different from bulk water, and the reviewers judge the diffusiophoresis explanation the more compelling one. Measured in: Physical chemistry, laboratory measurement. The interface phenomenon is well documented and still needs a theoretical explanation, which is a different statement from the one printed on a bottle. That no structuring device has shown a health benefit is our own reading of the absence of trials, not a finding from this review.

Who this may not transfer to:A laboratory interface effect at hydrophilic surfaces, not a persistent property of bottled or filtered water people drink.

What This Has to Do with Acupuncture

The best-supported physical account of acupuncture needling is mechanical. When a needle is rotated, it winds the collagen around it, deforming the connective tissue and signaling the fibroblasts in it. This is the origin of the sensation practitioners call needle grasp, and it connects needling to the fascial planes that channels partially follow. In serial sections of the human arm, the same group mapped an 80% correspondence between acupuncture point locations and connective-tissue planes. Its authors framed this as a hypothesis, and the 80% figure is an anatomical mapping in cadaver tissue, so it is a proposed partial mechanism, not proof that acupuncture treats any given condition. It holds without meridians being conduits of anything.

Studies of electrical skin impedance at acupuncture points are a separate matter. They exist, most are of low quality, and the results are contested. The stronger claim, that meridians are literal anatomical ducts, has not been replicated.

Where the Claims Stop

The same vocabulary is attached to claims that fail testing. Grading the frontier and grading effectiveness are two different jobs, kept apart here.

Structured, hexagonal or exclusion-zone water, as sold. The exclusion zone, a narrow layer at strongly hydrophilic surfaces that repels microspheres, is a laboratory effect several groups have reproduced. Its explanation is contested among physical chemists, with a diffusiophoresis account competing with the idea that the water there is structurally different. The consumer claim is a separate matter: bulk water reorganizes its hydrogen-bond network in trillionths of a second, so no lasting structured phase sits in a glass, and no structuring device has shown a health benefit.

Water crystals shaped by intention. The famous photographs came from a procedure with no blinding, in which the photographer knew which sample was which and a small number of attractive crystals were selected from thousands. It does not show that intention restructures water.

Detectable healing biofields. Electromagnetic fields around the body exist and are measured routinely, in an ECG for instance. A single coherent field that a practitioner can sense and manipulate is a separate claim. Tested under blinded conditions, practitioners could not detect a human energy field better than chance. Where people feel better after these treatments, the working explanation is attention, relaxation, ritual, and meaning, which are documented influences on how people feel.

Frequency therapy for disease. Radio waves at the powers these devices produce do not carry enough energy to destroy microbes, the disease claims have never held up in testing, and several sellers have been convicted of health fraud.

The main harm from frequency-cure devices is delay: someone postponing effective treatment while waiting for a device to work.

What the Evidence Supports

The body is electrically active and rhythmically organized. Its rhythms can be entrained by light, breath, movement, and load, and every part of that is supported. It also points to what to do: get light in the morning, breathe slowly, load your tissues, sleep in the dark. The evidence does not reach from entrainable rhythms to buying a frequency to cure a disease.

Common Questions

Are we electrical beings?

Yes, and it is ordinary cell biology. Every cell maintains a membrane voltage, nerves and muscle signal electrically, and wounds generate measurable direct-current fields that guide healing. What remains open is how much of body-wide organization voltage patterns control.

Do meridians exist?

Not as discrete anatomical conduits, which is what repeated searching has found. Channels do partially overlap fascial and connective-tissue planes, and those planes carry both mechanical and piezoelectric signals, a testable overlap. The classical map remains a clinical and descriptive system, not an anatomical one.

Is there anything to red light, PEMF and the other electrical devices?

Some of them, for specific indications, at specific doses. That is a different question from this page, and it turns on the indication, not the category. Each one is graded on its own page.
