This overview describes the German New Medicine (GNM) framework for academic analysis. Every claim below is reported as a claim, not as established fact.
What GNM claims to be
German New Medicine was devised in the 1980s by former physician Ryke Geerd Hamer. It asserts that virtually every disease begins with a specific, unexpected, isolating psychological shock (a "conflict shock" or DHS), and that body, brain and psyche run on "five biological laws."
The five 'biological laws' (as claimed)
- The Iron Rule: every disease starts with a conflict shock that strikes psyche, a specific brain point, and the corresponding organ simultaneously.
- Two-phase course: when the conflict resolves, every disease passes through a conflict-active phase and a healing phase.
- Ontogenetic system of tumors: each organ's response is governed by its embryonic germ layer.
- Ontogenetic system of microbes: microbes act on cue during the healing phase rather than causing disease.
- The 'quintessence': diseases are reframed as 'meaningful biological special programs' rather than malfunctions.
Germ layers and brain relays (claimed)
GNM sorts organs by germ layer and assigns each a brain control center: endoderm → brainstem; old mesoderm → cerebellum; new mesoderm → cerebral medulla; ectoderm → cerebral cortex. Endodermal/old-mesodermal tissues are said to grow in the active phase and be broken down by microbes in healing; ectodermal and new-mesodermal tissues are said to lose tissue (ulcers, necrosis) in the active phase and replenish, with swelling, in healing.
The two-phase course and 'healing crisis'
GNM claims a conflict-active phase (cold extremities, stress, weight loss) is followed — once the conflict resolves — by a healing phase (warmth, swelling, fatigue, inflammation) punctuated by a brief 'epileptoid crisis.' Many ordinary symptoms of disease are reinterpreted as 'healing.'
Biological handedness and laterality
GNM claims a person's 'biological handedness' (tested by clapping) plus whether a conflict concerns 'mother/child' or 'partner' determines which side of the body is affected — a rule it uses to explain, for example, which breast is involved.
Critical analysis
None of the 'five biological laws' has been validated in controlled, peer-reviewed research. The germ-layer-to-brain mapping is not recognized by embryology or neuroscience, and the claimed ring-shaped brain marks ("Hamer foci") are attributed by radiologists to ordinary CT artifacts. The framework is unfalsifiable, relies on anecdote, and contradicts established causes of disease (pathogens, mutations, toxins, autoimmunity). Most dangerously, by reframing tumors, infarctions and leukemia as benign 'healing,' it has discouraged effective treatment.
