AVIG AND KNMG. BIG registration: 99022085801

Dr. de Klyn’s centre for holistic medicine treats people with chronic diseases who did not respond sufficiently to conventional therapies and patients who prefer a more natural treatment pathway. The focus of the treatment is on the activation and resetting of the immune system.

The clinic uses conventional and complementary (CAM) therapies, the treatment depends upon the patients’ specific medical diagnosis. The treatment is suitable for patients who are suffering from chronic, invalidating diseases, such as chronic fatigue syndrome, irritable bowel syndrome, arthritis, cancer, fibromyalgia, auto-immune diseases, allergy, chronic inflammation, and chronic forms of infectious diseases like Lyme disease and Q-fever.


The holistic treatments are mainly based on naturopathy and terrain medicine. Naturopathy is a treatment designed to awaken the body’s inner defence system (vis medicatrix naturae). Whereas Terrain medicine considers the body fluids as the cause of the illness. The treatment is designed to restore the balance in the terrain of the body.


As the name suggests, holistic medicine is a term for treating the individual as a whole. This refers to every aspect of the person, including the physical, psychological, mental, energetical, relational and ecological aspects.

Dr. de Klyn has expertise in treating chronic diseases that have developed as a result of bacterial or viral infection (Pfeiffer, Lyme disease, Q-fever, chlamydia, whooping cough, herpes, mycoplasm etc) with autovaccine therapy (see: ).
