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 homeopathy, the one true, simple and natural art of healing, to give the patient at one time two different medicinal substance.
*Two substances, opposite to each other, united into neutral Natrum and middle salts by chemical affinity in unchangeable proportions, as well as sulphurated metals found in the earth and those produced by technical art in constant combining proportions of sulphur and alkaline salts and earths, for instance (natrum sulph. and calcarea sulph.) as well as those ethers produced by distillation of alcohol and acids may together with phosphorus be considered as simple medicinal substances by the homÅ“opathic physician and used for patients. On the other hand, those extracts obtained by means of acids of the so-called alkaloids of plants, are exposed to great variety in their preparation (for instance, chinin, strychnine, morphine), and can, therefore, not be accepted by the homÅ“opathic physician as simple medicines, always the same, especially as he possesses, in the plants themselves, in their natural state (Peruvian bark, nux vomica, opium) every quality necessary for healing. Moreover, the alkaloids are not the only constituents of the plants.
