Preparation of Medicines
Organon Aphorism §273
In no case under treatment is it necessary and therefore not permissible to administer to a patient more than one single, simple medicinal substance at one time. It is inconceivable how the slightest doubt could exist as to whether it was more consistent with nature and more rational to prescribe a single, simple medicine at one time in a disease or a mixture of several differently acting drugs. It is absolutely not allowed in homoeopathy, the one true, simple and natural art of healing, to give the patient at one time two different medicinal substance.
