Homoeopathic medicines are energy. They are prepared by extreme dilutions and contain no material substance in them above a certain potency. This eliminates the dangers and hence, no side effects. But still large overdose of homoeopathic medicine than what is being prescribed by the physician is not considered to be healthy.
The therapeutic ratio ( dose for “effective” treatment/Dose for harmful effects) is massively high for homeopathy. Homeopathy follow the Hippocratic Oath… “first, do no harm.”
Homeopathic medicines are not employed against one particular area or organ of the body. The homeopathic remedy is chosen because it matches as closely as possible the totality of symptoms of the patient.
