Functional Medicine is a systems biology–based approach that focuses on identifying and addressing the root cause of disease. This book explains in detail how the Functional Medicine approach of Dr. Schimmel can be applied. 

The term "functional medicine" got its place in the field of naturopathy through the work of Dr. Helmut Schimmel . 'Functional medicine" is the area that tries to diagnose and treat functional disorders in the patient

Functional diseases could be described as disorders based on irritations of the energetic, vegetative, neurophysiological and the associated biochemical processes and stimulus responses.

The disorders can be caused by biological (viruses, bacteria, etc.), chemical (nutrition, toxins), mechanical (scars, etc.), genetic predispositions and psychological disorders. "Functional medicine" therefore uses its own diagnostic and diagnostic methods and specially developed therapeutic approaches, which are based both on clinical considerations and on energy and information medicine considerations.

"Functional medicine" and resonance homeopathy, as described by Dr. Schimmel, make use of their own diagnostic and diagnostic methods and a specially developed therapy approach, which are based on clinical considerations as well as on energy- and information-medicine considerations.

Dr. Schimmel was looking for an answer to what might be the cause of functional disorders and chronic illnesses. But it took him a few years before he developed his theoretical models .

“A consequent continuation of conventional medicine philosophy must inevitably lead to an increase in symptomatic therapy. Since the cause is not eliminated in most cases, more and more control loops are disturbed, which in the end results in organ damage."

In the 1980s, people tried to completely cleanse the body of all toxins with nosodes. However, this was too time-consuming and cost-intensive and Dr. Schimmel therefore looked for a better solution. His observation showed that it is important to identify the main toxins he calls "key toxins". After eliminating them, he now observed that the organism was able to excrete and/or tolerate the other toxins still remaining in the body much better.

In the case of a viral infection, the virus tries to get into the DNA of the host cell quickly in order to multiply there. As a counter reaction of the organism, the immune defense tries to eliminate the pathogen. Depending on the state of the immune system, 5 pathogenetic phases of infection can be described, whereby the virus is neutralized, eliminated or recycled in the citric acid cycle. However, if there are disturbances in the immunological activity, the breaking up process can get stuck in any phase.
