For eg, if arsenic in crude from can create nausea and vomiting in a healthy human, the same arsenic when potentized (a method of preparing homeopathic Remedies in which the material content is programmatically lowered but it’s electromagnetic properties remaining) can cure a patient of vomiting and nausea. This is a very layman explanation of the principle.
Understanding the same principle bit more clearer, the same homeopathic arsenic can cure the patient of the deathly anxiety which it’s crude counterpart can produce when administered to healthy person.
We just took our understanding far more deeper into the quantum realm where the recent most advances in science are focused. We employ our medicines to deal with the emotions… pin pointedly, those emotions which are causing you the disease that caused you perhaps to surf this website. Thats why we say YOUR EMOTIONS ARE OUR DIAGNOSIS.
Similar is the case with HOMEOPATHY… It acts on the sentient nerves which puts an end to the unhappy or unpleasant Sensation to the system after which, the body always knows, how to reach it’s original state of health that is called PHYSIOLOGY.
