New German Medicine: What It Claims, What the Evidence Says, and What You Should Know Before Exploring It

There are few topics in the holistic health world that generate as much passion, and as much caution, as New German Medicine (NGM). Some people encounter it during a health crisis and find that its framework resonates with their lived experience. Others, including many medical authorities worldwide, view it as a dangerous pseudoscience that has caused real harm. Both of these things are true at the same time, and that tension is worth sitting with before you form an opinion.

This guide doesn't promote NGM as a treatment, and it won't tell you to avoid learning about it either. What it will do is explain, as clearly and honestly as possible, what NGM claims, how those claims are viewed by the scientific community, what the safety concerns are, and where the idea of emotional conflict influencing physical health actually does have legitimate scientific footing. You deserve the full picture.

What Is New German Medicine?

New German Medicine (also called Germanic New Medicine or GNM, from the German Germanische Heilkunde) is a medical theory developed by Ryke Geerd Hamer, a German physician, in the early 1980s. Hamer proposed that every disease, including cancer, originates from an unexpected, unresolved emotional shock he called a "Dirk Hamer Syndrome" (DHS), named after his son Dirk, who died following a shooting accident in 1978. Hamer himself was later diagnosed with testicular cancer and believed the two events were connected.

From there, he built a framework he called the Five Biological Laws, which attempt to explain how specific emotional conflicts correspond to specific diseases in specific organs, via specific lesions in the brain. The system also proposes a two-phase model of illness: an active conflict phase (during which disease develops) and a healing phase (during which conventional symptoms like inflammation, fever, or tumour activity actually represent the body's recovery).

It's a coherent internal system. But coherence is not the same as evidence, and that distinction matters enormously when serious illness is involved.

The Origins: A Personal Tragedy Becomes a Theory

Hamer was a qualified physician in Germany, holding his licence from 1963. After his son was shot and later died in 1978, Hamer developed testicular cancer. He connected these two events causally, not metaphorically, and spent years researching cancer patients, looking for similar emotional shocks preceding their diagnoses. He believed he found consistent patterns, and presented his findings to the University of Tübingen in 1981 as a post-doctoral thesis. The university declined to evaluate it. Hamer interpreted this as institutional suppression. The scientific community interpreted it as his thesis not meeting the required standards for evidence.

His medical licence was revoked in Germany in 1986 for malpractice. He was subsequently convicted multiple times in Germany and France for practising medicine without a licence. He eventually settled in Norway, where he died in 2017.

After losing his licence, Hamer increasingly incorporated conspiratorial elements into his work, including the antisemitic claim that Jewish leaders were deliberately suppressing GNM to allow non-Jewish people to die from cancer. This is not a fringe footnote. It's embedded in his published writings and is important context for anyone researching this framework.

The Five Biological Laws: What GNM Actually Claims

According to Hamer, every disease follows five universal laws:

• The First Law (the Iron Rule of Cancer) states that every disease, especially cancer, is triggered by a biological conflict shock, an event that is unexpected, isolating, and experienced with no prior strategy to handle it. This shock simultaneously impacts the psyche, a specific area of the brain, and a corresponding organ.
• The Second Law proposes that every disease has two phases: a conflict-active phase and, if the conflict is resolved, a healing phase. GNM teaches that many symptoms people experience as illness (fever, inflammation, swelling) are actually healing symptoms.
• The Third Law is the Ontogenetic System of Tumours, which links specific types of cancer to specific emotional conflicts. For example, GNM claims lung cancer corresponds to a "death fright conflict," and breast cancer to a "nest worry conflict."
• The Fourth Law relates to the role of microbes. GNM claims that bacteria, viruses, and fungi don't cause disease but instead assist in healing once a conflict is resolved.
• The Fifth Law describes what GNM calls the "quintessence," the assertion that disease is a biological survival programme, not an error of nature.

These laws are described by Hamer's followers as a unified, internally consistent science. Independent scientists have not been able to verify them through controlled research.

What the Medical and Scientific Community Says

The medical consensus on NGM is clear and consistent: its claims have not been validated by independent research, and its approach to serious illness carries documented risks.

The German Cancer Society reaffirmed in 2024 that GNM is both harmful and unethical. The Swiss Cancer League has described Hamer's approach as "dangerous, especially as it lulls patients into a false sense of security, depriving them of effective treatments." The Institute for Strategic Dialogue estimates that deaths linked to Hamer's methods range from 80 court-documented cases to approximately 500 people since 1983, predominantly people who delayed or refused conventional cancer treatment on the basis of GNM principles.

In Australia, the Therapeutic Goods Administration (TGA) regulates health claims and has consistently maintained that unproven alternative frameworks should not replace evidence-based medical care for serious conditions. While the TGA has not issued a specific advisory naming NGM, its broader position on unproven cancer treatments is well-established.

If you're encountering NGM during a cancer diagnosis or any serious illness, please speak with your treating physician before making any decisions based on it.

Where the Idea Isn't Wrong: The Legitimate Science of Mind and Body

Here's where it gets genuinely interesting, and why so many people feel drawn to NGM even when they're aware of its problems. The core intuition, that emotional experience affects physical health, is not pseudoscience. It's one of the most well-supported ideas in modern medicine.

Psychoneuroimmunology (PNI) is the established scientific field that studies exactly this. Research in PNI has clearly demonstrated that chronic stress suppresses immune function, that unresolved trauma changes the biochemistry of the brain and hormonal systems, and that psychological wellbeing has measurable effects on immune resilience, inflammation levels, and recovery from illness. The gut-brain axis, cortisol and HPA axis dysregulation, the role of adverse childhood experiences in adult disease risk, all of this is peer-reviewed, reproducible science.

The difference between PNI and NGM is significant. PNI shows that emotional states influence health in complex, probabilistic ways across populations. NGM claims that specific emotional conflicts cause specific diseases in specific organs in specific individuals, in a deterministic, one-to-one mapping. That's a very different kind of claim, and one the evidence doesn't support.

PNI also doesn't tell cancer patients to avoid chemotherapy. NGM, in many of its formulations, does.

Why People Find NGM Compelling

It's worth being honest about this. NGM offers something that conventional medicine often doesn't: a why. When someone is diagnosed with a serious illness, the medical system can explain the mechanism of disease and recommend treatment, but it rarely has time to explore the patient's inner life, their grief, their losses, their unresolved conflicts. NGM steps into that gap and offers meaning. That's a powerful thing.

Many people who explore GNM aren't anti-science. They're people in pain who want to understand what's happening in their bodies, and who feel that the emotional dimension of their experience isn't being acknowledged. That need is completely legitimate. The concern is that the framework built around it doesn't hold up, and that following it without also engaging with conventional medicine can be genuinely dangerous.

If You're Drawn to the Emotional Roots of Illness

If what attracts you to NGM is the idea that unresolved emotional experiences contribute to physical health, there are well-researched, safe approaches that explore exactly that territory without the risks.

Root Cause Therapy, somatic coaching, and trauma-informed counselling all work with the relationship between emotional history and physical wellbeing. EMDR (Eye Movement Desensitisation and Reprocessing) is one of the most rigorously researched trauma therapies available. The Emotion Code and Kinesiology both work from the premise that the body holds emotional experience and can be supported through releasing it.

None of these ask you to abandon medical care. All of them can work alongside it.

If you're looking for a practitioner to support your emotional and physical wellbeing, Bodhi Holistic Hub connects you with verified holistic practitioners across Australia, including trauma-informed therapists, somatic coaches, and counsellors who take the mind-body connection seriously.

Frequently Asked Questions

What is New German Medicine in simple terms?
NGM is a medical theory developed by Ryke Geerd Hamer, a German former physician, which proposes that all disease originates from specific emotional shocks. It has not been validated by independent scientific research and has been widely criticised by medical authorities for discouraging people from seeking conventional treatment.

Is New German Medicine the same as Germanic New Medicine?
Yes. Hamer used several names for his system over the decades, including German New Medicine, New Medicine, and, most recently, Germanische Heilkunde (Germanic Healing Knowledge). They all refer to the same framework.

Is there any truth to the idea that emotions affect health?
Yes, and this is well-established science. The field of psychoneuroimmunology has documented extensively how stress, trauma, and emotional states influence immune function, inflammation, and overall health. This is meaningfully different from NGM's claim that specific conflicts cause specific diseases in a predictable, one-to-one way.

Is New German Medicine legal in Australia?
Holding the beliefs associated with NGM isn't illegal. However, practising medicine without a licence is, and making therapeutic claims that a product or practice can treat serious conditions like cancer is regulated by the TGA. If someone is offering NGM "consultations" and advising you against conventional medical treatment, that warrants real caution.

Can NGM be used alongside conventional medicine?
Some people use the emotional reflection aspects of NGM as a way to explore meaning alongside their medical treatment, rather than instead of it. If you choose to do this, keeping your treating doctor informed is essential, and any framework that advises you to stop or delay medical treatment should be treated with significant scepticism.

How do I find a reputable practitioner for mind-body work?
Look for practitioners with recognised qualifications in fields like counselling, somatic therapy, or trauma-informed coaching. Platforms like Bodhi Holistic Hub list verified practitioners who have been assessed against professional standards, making it easier to find someone with genuine training rather than self-declared expertise.

What happened to Ryke Geerd Hamer?
Hamer's medical licence was revoked in Germany in 1986. He was convicted multiple times in Germany and France for practising medicine without a licence. He died in Norway in 2017.
