The 5 Biological Laws of German New Medicine, Explained (with Examples)

In short: The five biological laws are the founding principles of German New Medicine (GNM), set out by the German physician Ryke Geerd Hamer from the early 1980s. They propose that (1) every "disease" begins with an unexpected conflict shock that registers in the psyche, a specific brain area, and an organ at the same moment — the Iron Rule; (2) it then runs in two phases, conflict-active and then healing, if the conflict resolves; (3) a tissue's embryonic germ layer decides which part of the brain controls it and whether it adds or loses cells; (4) microbes act as helpers in the healing phase rather than as causes of disease; and (5) every so-called disease is a meaningful biological special program with a survival purpose. Together they form an alternative framework, built on Hamer's clinical observations and separate from conventional medicine.

If you have read what German New Medicine is and want the framework's actual rules, this is where to start. Everything GNM says about a symptom — every conflict theme, phase, and organ mapping on this site — is an application of these five laws. This guide explains each law in plain English, sets them side by side in one table, walks through worked examples of the laws operating together, and explains where they came from.

A note on the name: in general biology, "biological laws" (or rules) are broad patterns observed in living things — Bergmann's rule, which links larger body size to colder climates, is a classic example. This guide is about something different: the five laws of Dr. Hamer's GNM framework, which he called biological "natural laws."

The 5 Biological Laws at a Glance

Law	What GNM proposes	Example, as GNM reads it
1. The Iron Rule	An unexpected, acute, isolating conflict shock (a DHS) starts a program in the psyche, a brain relay, and an organ at once, and the content of the conflict decides which organ	A sudden separation registers on the skin; a situation you "can't stomach" registers in the gut
2. The two-phase law	If the conflict resolves, the conflict-active (stress) phase is followed by a healing (repair) phase	Holding up through a crisis, then feeling wiped out once it ends
3. The ontogenetic system	A tissue's embryonic germ layer sets which brain area controls it and whether it adds or loses cells during conflict activity	The gut lining adds cells; the outer skin loses them
4. The ontogenetic system of microbes	Fungi, mycobacteria, and bacteria act as healing-phase helpers matched to germ layers, not as the cause of disease	Healing-phase fever and inflammation read as microbes at work
5. The Quintessence	Every so-called disease is a Significant Biological Special Program (SBS) with a survival purpose	Bone that thins under a blow to self-worth rebuilds stronger

The sections below take each law in turn. After that, three worked examples show the five laws operating together, the way GNM intends them to be read.

The First Biological Law: The Iron Rule

The First Biological Law is known as the "Iron Rule" — in full, Hamer's "Iron Rule of Cancer," because he formulated it for cancer before applying it to every kind of illness. It proposes that every meaningful biological program begins with an unexpected, acute, and isolating conflict shock that strikes three levels at the same instant: the psyche, a specific brain relay, and a corresponding organ. GNM calls this moment a DHS (Dirk Hamer Syndrome), named after the son whose death set Dr. Hamer on this path.

Hamer set out the law in three criteria:

1. Every program starts with a DHS — a shock that catches the person off guard, as opposed to stress that builds gradually.
2. The content of the conflict determines which organ is affected and which area of the brain controls the program.
3. The program runs in step on all three levels — psyche, brain, and organ — from the moment it begins.

What makes this law distinctive is its specificity. In GNM's account, a separation conflict — feeling a sudden loss of physical contact — affects the skin and is mediated by the sensory cortex. An "indigestible morsel" conflict — something you figuratively "can't stomach" — affects the digestive tract and is mediated by the brainstem. A self-devaluation conflict — feeling suddenly worthless — affects bones, muscles, or connective tissue and is mediated by the cerebral medulla.

GNM roots these conflict themes in biological survival rather than abstract psychology. In its account, animals experience them concretely: a territory is physically lost, a pup is literally separated from its mother, food is actually indigestible. Humans experience transposed versions — a divorce feels like territorial loss, a child leaving for college activates separation wiring, a betrayal becomes an emotional "morsel" that cannot be processed.

The First Law also brings in biological handedness. GNM holds that for a right-handed person, a conflict involving a mother or child shows on the left side of the body and a conflict involving a partner shows on the right, with the pattern reversed for left-handers; the rule applies to organs controlled from the cerebellum, cerebral medulla, and cerebral cortex. GNM uses a clapping test to establish handedness: the hand that lands on top is taken as the leading hand.

The Second Biological Law: The Two-Phase Pattern

The Second Biological Law — Hamer's law of the two phases — describes the pattern every biological program follows: a conflict-active phase and a healing phase. If the conflict resolves, the program moves through both phases in a predictable sequence. If it does not resolve, the person remains in the conflict-active phase indefinitely — what GNM calls a "hanging conflict."

The conflict-active phase begins at the moment of the DHS and persists as long as the conflict remains unresolved. The autonomic nervous system shifts into sympathicotonia — a sustained stress state. The person experiences compulsive thinking about the conflict, sleep disruption (especially waking around 3 AM), loss of appetite, cold extremities, rapid heartbeat, and elevated blood pressure. This is the "cold phase." At the organ level, depending on which tissue type is involved, cells either proliferate or deteriorate to serve the biological purpose of the program.

The healing phase begins the instant the conflict resolves — what GNM calls "conflictolysis." The autonomic nervous system swings into vagotonia — a deep rest-and-repair state. Fatigue sets in, appetite returns, hands warm up, blood pressure drops, and sleep deepens. This is the "warm phase." At the organ level, repair processes begin: swelling, inflammation, fever, discharge, and pain are all characteristic healing symptoms.

The healing phase itself has two distinct stages, separated by a critical turning point:

PCL-A (the first half of healing) involves maximum swelling and fluid accumulation as the body repairs tissue. At the brain level, GNM says edema forms around the affected relay, visible on CT scans as a dark, hazy ring. Physical symptoms are at their most intense. GNM argues that this is when most people seek medical attention — and, in its view, often receive a diagnosis just as the body is repairing.

The Epileptoid Crisis is, in GNM's account, a brief but intense moment at the peak of healing where the body suddenly shifts back into sympathicotonia. Its purpose, GNM says, is to expel accumulated fluid from both the organ and the brain relay. Depending on the conflict type, GNM describes this crisis as showing up as a seizure, a heart palpitation episode, a moment of dizziness, a migraine peak, or a brief fever spike. GNM holds that the crisis is as strong as the conflict-active phase that preceded it, and cautions that some crises can be dangerous, especially after a long, intense conflict. After the crisis passes, the body enters the second half of healing.

PCL-B (the second half of healing) is the scarification and restoration phase. Swelling recedes, function normalizes, and the day-night rhythm returns to balance. At the brain level, connective tissue (neuroglia) fills in the affected area, which GNM describes as the brain's own repair.

GNM uses these two phases to reframe many common experiences: getting sick on vacation, developing symptoms after a breakup resolves, or feeling exhausted once a stressful period ends. In its reading, such symptoms signal that the body has shifted into repair mode rather than that something new has gone wrong. ChatGNM helps you explore which phase GNM would place you in by asking about your symptom timing and the life events surrounding it.

The Third Biological Law: The Ontogenetic System of Germ Layers

The Third Biological Law — Hamer's "ontogenetic system of tumors" — organizes every organ and tissue in the body according to its embryonic germ layer origin, and proposes that this origin determines how the tissue responds during a biological program. This is where GNM becomes systematic: it maps the entire body to the three germ layers that form in the first weeks of embryonic development, and gives each layer its own conflict-response pattern.

What Are the Three Germ Layers?

During embryonic development, a cluster of cells differentiates into three foundational layers: the endoderm (innermost), the mesoderm (middle), and the ectoderm (outermost). Every organ and tissue in the body develops from one of these layers. In GNM, each germ layer is controlled by a specific region of the brain and follows a specific pattern during conflict activity and healing.

Endoderm (controlled by the brainstem): The oldest germ layer, corresponding to the most ancient survival functions — breathing, digesting, and reproducing. Organs include the lungs (alveoli), liver, pancreas, stomach lining, intestines, thyroid, bladder, kidney collecting tubules, and uterine tissue (relevant to conditions like endometriosis). During a conflict-active phase, endodermal tissues generate cell growth to increase functional capacity. During healing, the extra cells are broken down and removed. The conflict themes are archaic: "death-fright" (lungs), "indigestible morsel" (digestive organs), "existence" or "abandonment" (kidney collecting tubules).

Old mesoderm (controlled by the cerebellum): This layer produces protective structures — the inner skin layer (corium), pleura, peritoneum, and pericardium — as well as the breast glands. Like the endoderm, old mesodermal tissues generate cell growth during conflict activity and break down the extra tissue during healing. The protective layers are tied to "attack" conflicts — feeling attacked in the chest, the abdomen, or on the skin — while the breast glands are tied to nest-worry conflicts about the well-being of someone in one's care.

New mesoderm (controlled by the cerebral medulla): This layer produces structural support tissues — bones, cartilage, muscles, tendons, ligaments, blood vessels, lymph nodes, ovaries, testicles, and kidney tissue. Unlike the older layers, new mesodermal tissues undergo cell loss during conflict activity (for example, bone density decreases) and then rebuild during healing. The conflict themes center on self-devaluation — feeling inadequate, worthless, or incapable.

Ectoderm (controlled by the cerebral cortex): The newest germ layer, producing the outer skin (epidermis), sensory organs, and the linings of many ducts and passages (bronchial tubes, bile ducts, milk ducts, coronary vessels, and part of the stomach lining). Ectodermal tissues undergo cell loss or ulceration during conflict activity, and then repair and refill during healing. The conflict themes concern social contact — separation from a loved one (skin), territorial anger (bile ducts), and territorial loss or sexual conflicts (coronary vessels).

Why Does the Germ Layer Matter?

Knowing which germ layer an organ belongs to tells you three things in GNM's system: which brain region controls it, what happens to the tissue during conflict activity (growth versus loss), and what conflict theme is likely involved. That is what turns symptom interpretation into a structured analysis in the framework. A skin rash (ectoderm) follows the opposite tissue pattern from a lung growth (endoderm), and GNM links each to an entirely different type of emotional conflict — which is how the framework finds order in what looks like a chaos of symptoms.

The Fourth Biological Law: Microbes as Healing-Phase Repair Crews

The Fourth Biological Law — Hamer's "ontogenetic system of microbes" — addresses the role of bacteria, fungi, and mycobacteria. Rather than viewing microbes as invaders that cause disease, GNM proposes that they are repair crews the organism uses only during the healing phase, matched to the germ layer of the tissue being repaired.

In GNM's account, fungi and mycobacteria (such as tuberculosis bacteria) work on the oldest tissues — those controlled from the brainstem and cerebellum — breaking down the extra cells built during conflict activity. The fever, night sweats, inflammation, and discharge that accompany this are read as the clean-up in progress. Other bacteria are said to help rebuild tissue lost during conflict activity in the newer layers, such as bone. For many cortex-controlled tissues, GNM reinterprets what medicine calls infections — bronchitis, hepatitis, many skin eruptions — as healing-phase repair.

GNM also holds that these microbes stay inactive while a conflict is active and become active only once healing begins, which is why, in its account, "infections" appear after a stressful period ends rather than during it.

The framework also acknowledges that an intense healing phase can bring complications. Hamer himself held that when microbial activity becomes too intense, temporary use of antibiotics is warranted to prevent complications such as septic shock.

The Fifth Biological Law: Every Program Has a Biological Purpose

The Fifth Biological Law — sometimes called the "Quintessence" — ties everything together by proposing that every so-called disease is actually a Significant Biological Special Program (SBS) with a specific biological purpose. In this view, these programs are not errors, breakdowns, or attacks but evolutionary adaptations that let an organism override normal functioning to deal with a biological emergency.

GNM illustrates the law with examples like these. After a sudden blow to someone's sense of worth — a self-devaluation conflict — the affected bone is said to lose substance during conflict activity and then rebuild, stronger than before, once the conflict resolves: reinforcement for the next time. Faced with an "indigestible morsel," the intestinal lining is said to add cells that produce more digestive juices so the morsel can be broken down. And during a separation conflict, GNM describes the outer skin becoming less sensitive, along with a temporary dip in short-term memory, which it frames as a way to "forget" the separation while it lasts.

The Fifth Law invites a fundamental shift in perspective. Rather than seeing the body as something that breaks down and attacks itself, GNM frames it as an intelligent system running programs designed to enhance survival — symptoms, in this view, are the body's solution to a perceived biological emergency rather than the problem itself.

GNM itself acknowledges the limits of this framing: programs that run too long or too intensely, or that obstruct a vital passage, can create real complications. The Fifth Law simply reframes the question from "what is wrong with my body?" to "what is my body trying to accomplish?"

How Do Conflicts Map to Specific Organs?

The mapping between conflict types and organs follows the logic of the three germ layers and their evolutionary functions. GNM organizes this mapping through a comprehensive reference called the Scientific Chart (based on the GNM Biological Programs overview), which catalogs every tissue type alongside its controlling brain relay, germ layer origin, conflict theme, and behavior during both phases.

Here is a simplified overview of how major conflict themes connect to organ groups:

Conflict Theme	Affected Tissues	Germ Layer	Brain Control
Death-fright, suffocation fear	Lung alveoli	Endoderm	Brainstem
Indigestible morsel (can't process)	Small/large intestine, stomach	Endoderm	Brainstem
Existence/abandonment	Kidney collecting tubules	Endoderm	Brainstem
Attack against integrity	Pleura, peritoneum, pericardium, corium skin	Old mesoderm	Cerebellum
Nest-worry (worry about someone in your care)	Breast glands	Old mesoderm	Cerebellum
Self-devaluation (feeling worthless)	Bones, muscles, joints, lymph nodes	New mesoderm	Cerebral medulla
Separation (loss of contact)	Epidermis (outer skin)	Ectoderm	Sensory cortex
Territorial anger	Bile ducts, part of the stomach lining	Ectoderm	Cerebral cortex

This is not an exhaustive list — the full Scientific Chart maps dozens of specific conflict variations to precise tissue and brain relay locations. But even this overview reveals the internal logic: ancient survival threats map to ancient brain regions and tissues, while more complex social and territorial conflicts map to newer brain regions and tissues. To see how GNM applies the mapping to individual symptoms, browse the GNM symptom index.

What Role Does the Brain Play in GNM?

The brain serves as the central mediator between the psyche and the body in GNM. When a conflict shock occurs, it registers in a specific brain relay — the precise location depends on the nature of the conflict and corresponds to the organ or tissue that will be affected. Dr. Hamer described these impact sites as concentric ring formations visible on brain CT scans, which he called "Hamer Foci."

In GNM, the brain's organization mirrors the evolutionary development of the germ layers. The brainstem (the oldest brain region) controls endodermal organs. The cerebellum controls old mesodermal tissues. The cerebral medulla controls new mesodermal structures. The cerebral cortex (the newest brain region) controls ectodermal tissues. This parallel between brain architecture and organ embryology is central to the Third Biological Law.

GNM describes the Hamer Focus changing with the phases: sharp, clearly defined rings during the conflict-active phase; a darker, hazy, fluid-filled configuration during healing; and, as healing completes, connective tissue (neuroglia) filling in the area, which appears lighter on scans.

The brain also mediates the laterality pattern. Each brain hemisphere (with the exception of the brainstem) controls the opposite side of the body. In GNM, combined with biological handedness, this determines which side of the body manifests symptoms — providing another layer of diagnostic specificity that GNM practitioners use to identify which conflict is active.

Worked Examples: The Five Biological Laws in Action

The laws are meant to be read together: GNM's claim is that any one symptom, run through all five, produces a single coherent account. Here is how GNM would read three everyday examples, each from a different germ layer.

Example 1: Diarrhea After a Situation You "Couldn't Stomach"

• First Law: An unexpected, upsetting situation — a bitter dispute, say — lands as an "indigestible morsel" conflict, a theme GNM assigns to the intestinal lining, controlled from the brainstem.
• Third Law: The intestinal lining is endoderm, so during conflict activity it adds cells.
• Second Law: While the dispute drags on, the gut is quiet — or even constipated. When it settles, the healing phase begins.
• Fourth Law: GNM says fungi and mycobacteria now break the surplus cells down, which it reads as the cramps, loose stools, and sometimes night sweats that follow.
• Fifth Law: The purpose, in GNM's reading, was more digestive capacity for a "morsel" the person could not process.

More in GNM and diarrhea.

Example 2: A Rash That Appears After a Reunion

• First Law: A sudden separation — a partner away for months, a parent back at work — lands as a separation conflict, which GNM assigns to the outer skin, controlled from the sensory cortex.
• Third Law: The epidermis is ectoderm, so during conflict activity it loses cells: the skin turns dry, rough, and less sensitive.
• Second Law: When contact returns, the healing phase begins and the skin rebuilds — red, swollen, and itchy. GNM says this is why such rashes so often flare after a reunion rather than during the separation.
• Fifth Law: GNM describes the dulled sensitivity, along with a temporary dip in short-term memory, as a way to "forget" the separation while it lasts.

If the rash keeps coming back around a particular place or person, GNM reads that as a track reactivating the program (see below). More in GNM and eczema.

Example 3: Joint Pain After a Blow to Your Confidence

• First Law: Being passed over, criticized, or failing at something that matters lands as a self-devaluation conflict. GNM assigns it to bone, joint, and connective tissue, controlled from the cerebral medulla — and reads the joint involved as a clue to the kind of blow (the hands for manual skill, the knees for keeping up).
• Third Law: Bone and joint tissue is new mesoderm, so during conflict activity it quietly loses substance, usually without pain.
• Second Law: Once confidence recovers, the healing phase brings warmth, swelling, and pain as the joint rebuilds — what GNM reads as arthritis.
• Fourth Law: GNM gives bacteria a role in rebuilding tissues such as bone during this phase.
• Fifth Law: The goal, in GNM's reading, is reinforcement: the bone rebuilds stronger, better prepared for the same kind of blow.

In each example the laws do different jobs: the First picks the tissue, the Third predicts what that tissue does, the Second ties the timing of the symptoms to the conflict, the Fourth gives microbes a repair role, and the Fifth supplies the reason. The GNM Scientific Chart is the reference tool GNM uses to apply this analysis to any organ or tissue.

What Are Tracks and Hanging Healings?

In GNM, "tracks" are sensory imprints recorded at the moment of the original conflict shock. The framework holds that the brain captures everything in the environment during a DHS — specific smells, sounds, tastes, locations, people present, time of day, even weather conditions. These become associated with the conflict and can reactivate the biological program upon future encounter, even after the original conflict has resolved.

GNM uses tracks to explain chronic and recurring conditions. If someone resolves a separation conflict but then repeatedly encounters a track element (a certain perfume, a specific place, a type of animal), the biological program reactivates each time. The person cycles between brief conflict-active phases and brief healing phases, never completing the full healing process. This is what GNM calls a "hanging healing," and it is the framework's account of conditions like chronic eczema, recurring digestive issues, persistent urinary symptoms, and ongoing hair loss.

GNM also reframes allergies through this lens. Rather than an overactive immune response to a harmless substance, an "allergy" in GNM terms is a track reactivation — the body replaying a biological program in response to an environmental cue that was present during the original conflict. Different people react to different substances because the tracks are unique to each person's specific conflict experience.

Identifying tracks is one of the most practical applications of GNM. It requires careful detective work — mapping when symptoms appear, what environmental factors are present, and tracing those elements back to when the original conflict occurred. GNM holds that resolving the conflict at the track level can break the cycle of chronic reactivation. This is exactly the kind of investigative work ChatGNM walks you through — connecting your recurring symptoms to the specific environmental cues and life events that keep reactivating the program.

Frequently Asked Questions

What are the 5 biological laws?

The five biological laws are the core of German New Medicine: (1) the Iron Rule — every program starts with an unexpected conflict shock (a DHS) that hits the psyche, a brain relay, and an organ at once; (2) the two-phase law — a conflict-active phase followed, if the conflict resolves, by a healing phase; (3) the ontogenetic system — a tissue's embryonic germ layer determines its brain control and how it responds; (4) the ontogenetic system of microbes — microbes as healing-phase helpers rather than causes of disease; and (5) the Quintessence — every so-called disease is a meaningful biological special program. Dr. Ryke Geerd Hamer formulated them, and together they are the foundation of the whole GNM framework.

What is an example of the biological laws in action?

A common GNM example is a rash that appears after a separation ends. GNM reads the sudden separation as the conflict shock (First Law) that hits the outer skin, an ectodermal tissue (Third Law), which loses cells while the separation lasts and rebuilds — red and itchy — once contact returns (Second Law); the purpose, in GNM's account, is to help "forget" the separation while it lasts (Fifth Law). The worked examples above take diarrhea, a rash, and joint pain through the laws one by one.

Who proposed the five biological laws?

Ryke Geerd Hamer (1935–2017), a German internist. He began developing them after his son Dirk died from a gunshot wound in 1978 and he was diagnosed with testicular cancer a few months later. He first called his system "New Medicine," later "Germanic New Medicine" (Germanische Neue Medizin) and "Germanische Heilkunde." The fuller story of his life and work is in our history of Dr. Hamer.

What are the five biological laws based on?

They are based on Dr. Hamer's clinical observations. According to GNM sources, he began in 1979, while working as an internist at an oncology clinic in Munich, to compare his patients' personal histories with their brain CT scans, and he reported that specific types of conflict shock corresponded to specific brain areas and specific organs. He said he confirmed these correspondences across more than 40,000 cases, and he organized them into the five laws. GNM is an alternative framework, separate from conventional medicine.

Are GNM's biological laws the same as biological laws in science?

No. In biology, "biological laws" or "rules" are generalizations about patterns in living things — Bergmann's rule (larger body size in colder climates) and Allen's rule (body proportions varying with climate) are well-known examples. Hamer's five biological laws are something different: the principles of his medical framework, describing how, in GNM's view, emotional conflicts relate to illness.

Can one person have multiple biological programs running at once?

Yes. GNM recognizes that people commonly have multiple active biological programs simultaneously, each triggered by a different conflict shock at a different time. These programs run independently of each other, each following its own timeline of conflict activity and healing. When multiple programs overlap — particularly if they affect related brain relays — the interactions can create complex symptom pictures. GNM practitioners use brain CT scans and detailed conflict histories to differentiate between overlapping programs.

What happens if a conflict never resolves?

If a conflict remains permanently unresolved, the person stays in the conflict-active phase indefinitely — a "hanging conflict." The biological program continues running at whatever intensity corresponds to the ongoing conflict. Many people live with low-intensity hanging conflicts for years with manageable symptoms. However, prolonged high-intensity conflicts can drain energy significantly through sleep disruption, appetite loss, and sustained stress-state physiology. GNM emphasizes that resolving the conflict — through practical life changes or genuine shifts in perception — is the key to transitioning into the healing phase.

How does GNM explain illnesses that spread through a group?

Conventionally, an illness that moves through a group is put down to microbes passing from person to person. GNM proposes a different reading: when several people fall ill at the same time, they may be in the healing phase of a similar conflict that resolved around the same moment — a stressful exam, a tense family event, a shared upset at work — and the microbes present are, in its view, healing-phase helpers rather than the original cause.

Do the Five Laws apply to mental health conditions?

GNM addresses what conventional medicine categorizes as mental health conditions through the concept of "constellations" — situations where two or more conflict programs are active simultaneously on both sides of the brain (both hemispheres). Different constellation patterns correspond to different behavioral and psychological presentations. This area of GNM is particularly complex and nuanced, and exploring it requires a solid understanding of the basic Five Laws first.

How do I know which phase I am in?

The two phases have distinct signatures in GNM. The conflict-active phase features stress symptoms: cold hands, disrupted sleep, loss of appetite, compulsive thinking about the conflict, and elevated heart rate. The healing phase features repair symptoms: fatigue, warmth, swelling, inflammation, fever, appetite return, and a general sense of relief or exhaustion. The transition point — conflictolysis — often correlates with a specific life event or inner shift that resolves the original conflict. Paying attention to when symptoms began and what changed in your life around that time provides the most useful clues.

Where can I study the five biological laws in depth?

The most comprehensive free resource for studying the biological laws in English is the LearningGNM website, built by Caroline Markolin, Ph.D. For a curated list of study materials, see our best GNM books and resources guide. To explore how the five laws apply to your own symptoms interactively, ChatGNM walks you through each law in the context of your specific situation.
