**Biological decoding** —also called Biodecoding, Bioreprogramming, German New Medicine— is a system originally developed by German physician Ryke Geerd Hamer in the 1980s and popularized in the Francophone and Latin American spheres by Christian Flèche and Claude Sabbah. It posits that every organic illness has a 'biological meaning' as an intelligent bodily response to a specific (real, lived, identifiable) emotional conflict.
**Core premise**: each organ is related to a specific type of conflict. Left female breast cancer is linked to 'nest' conflicts (intense worry for children or partner). Asthma is linked to 'territory in the air conflict' (not being able to breathe one's own space). Each symptom would be the body attempting to biologically resolve something the psyche did not resolve.
**Evidence status**: Biological decoding **lacks rigorous empirical support** in peer-reviewed medical research. Hamer was stripped of his medical license in Germany for dangerous medical practice. Multiple European and American medical bodies have warned against the method. It is documented that some extreme followers rejected conventional medical treatment for cancer, believing in decoding, with fatal consequences.
**However, significant presence in the field**: many clients who come to Family Constellations in Hispanic and Francophone cultures arrive with a biological decoding framework acquired in other spaces. Sabbah, especially, integrated elements of Psychogenealogy with decoding, and many therapists use decoding vocabulary.
**Responsible clinical position**: to recognize biological decoding as part of the cultural landscape without validating its unproven causal claims. To accompany clients who arrive with this framework to integrate what is useful (attention to the emotional dimension of the symptom) without abandoning the medical treatment their conditions require. Daniela and many serious constellators work along this line of non-confrontation but non-uncritical-validation.
Evidence and Contemporary Voices
Biological decoding, developed by Ryke Geerd Hamer in his German New Medicine (GNM), postulates that diseases arise exclusively from specific unresolved biological conflicts, without the intervention of viruses, bacteria, or genetic factors. This theory lacks support in peer-reviewed scientific literature. Systematic reviews in journals such as The Lancet Oncology (Kappauf et al., 1997) and studies by the Deutsche Krebsgesellschaft have refuted its premises, showing an absence of controlled clinical evidence. Christian Flèche and Claude Sabbah adapted GNM to psychotherapeutic contexts, integrating it into approaches such as Family Constellations, but without clinical trials validating its efficacy (Asociación Española Contra el Cáncer, 2020). Institutions like the American Cancer Society and the World Health Organization classify GNM as a dangerous pseudotherapy, with documented cases of delay in standard oncological treatments (Milazzo et al., 2006). There are no meta-analyses or longitudinal studies that corroborate the proposed conflict-disease causality.

Notes and Open Debates
Biological decoding is widely criticized for its rejection of the scientific method, absence of falsifiability, and documented clinical contraindications, such as increased mortality in oncology patients who abandon conventional treatments (Kappauf et al., 1997; Milazzo et al., 2006). It lacks randomized trials and promotes patient blame by attributing illnesses to individual emotional failures.
