Administer only one single, simple medicine at a time.
In no case of cure is it necessary to employ more than a single simple medicinal substance at one time with a patient. For this reason alone, it is inadmissible to do so. It is inconceivable that there could be the slightest doubt about whether it is more in accordance with nature and more reasonable to prescribe only a single, simple,273 well-known medicinal substance at one time in a disease or a mixture of several different ones. In homeopathy-the only true and simple, the only natural medical art-it is absolutely prohibited to administer to the patient, at one time, two different medicinal substances.
