Germanic Healing Knowledge (GHK), sometimes linked to the work of Dr Ryke Geerd Hamer, is a belief-based framework that proposes links between emotional conflicts and physical illness. It is not accepted as evidence-based medicine and its claims are not supported by mainstream medical or scientific research.
It should not be used as a substitute for medical diagnosis, conventional treatment, or evidence-based psychological care.
Germanic Healing Knowledge (GHK), also referred to as Germanic New Medicine or German New Medicine (GNM), is a framework developed by Dr Ryke Geerd Hamer in the 1980s. It proposes that specific emotional conflicts cause identifiable changes in the brain and body, and that illness follows predictable biological programmes linked to these conflicts.
Practitioners working within this framework typically offer consultations exploring emotional life history, perceived conflicts and stress patterns. Sessions may involve identifying what the practitioner describes as a "Dirk Hamer Syndrome" (DHS) or conflict shock, and interpreting physical symptoms through the lens of the GHK model.
It is important to be clear about the following:
Germanic Healing Knowledge should not be used as a basis for diagnosing, explaining or treating cancer or other serious medical conditions. Do not delay or decline medical assessment, investigations, surgery, chemotherapy, radiotherapy or prescribed treatment on the basis of GHK frameworks. If you have been advised to do so, please seek a second opinion from a qualified medical professional.
If you are exploring this approach because you are dealing with a serious health condition, a health scare or significant emotional distress, please also seek appropriate medical and psychological support. A GP, oncology team, or mental health professional can help you access evidence-based care alongside any complementary approaches you choose.
Germanic Healing Knowledge (also called German New Medicine or Germanic New Medicine) was developed by Dr Ryke Geerd Hamer, a German physician, from the 1980s onwards. Hamer proposed a system of biological laws linking emotional shocks to specific changes in the brain and body, and developed a framework for interpreting illness through this lens.
The approach attracted controversy because its claims conflict with established biomedical science, and concerns have been raised about cases where individuals declined conventional medical treatment in favour of GHK frameworks — sometimes with serious consequences. In the UK, it sits outside mainstream healthcare and is best approached with caution and alongside qualified medical advice.
