A SYNOPSIS
OF THE
Principles of Combination,
AS INVESTIGATED IN THE PRECEDING PAGES,
ARRANGED IN A TABULAR FORM
SO AS TO AFFORD THE STUDENT AN EASY
REFERENCE TO THE KEY LETTERS.
A Synopsis of the Principles of Medicinal Combination.
OBJECT I.
TO PROMOTE THE ACTION OF THE BASIS.
Key Letters. A A.—By combining the several different forms, or preparations of the same Substance. B B.—By combining the Basis with Substances which are of the same Nature, i. e, which are individually capable of producing the same effects, but with less energy than when in combination with each other. C C.—By combining the Basis with Substances of a Different Nature, and which do not exert any Chemical influence upon it, but are found by experience, or inferred by analogy, to be capable of rendering the stomach, or system, more susceptible of its action.
OBJECT II.
TO CORRECT THE OPERATION OF THE BASIS, BY OBVIATING ANY UNPLEASANT EFFECTS IT MIGHT BE LIKELY TO OCCASION, AND WHICH WOULD PERVERT ITS INTENDED ACTION, AND DEFEAT THE OBJECT OF ITS EXHIBITION.
D A.—By CHEMICALLY neutralizing, or MECHANICALLY separating, the offending ingredient. E B.—By adding some substance calculated to guard the stomach, or system against its deleterious effects.
OBJECT III.
TO OBTAIN THE JOINT OPERATION OF TWO, OR MORE MEDICINES.
F A.—By uniting those Medicines which are calculated to produce the SAME ULTIMATE RESULTS, but by modes of operation totally different. G B.—By combining Medicines which have entirely different powers, and which are required to obviate different symptoms, or to answer different indications.
OBJECT IV.
TO OBTAIN A NEW AND ACTIVE REMEDY, NOT AFFORDED BY ANY SINGLE SUBSTANCE.
H A.—By combining Medicines which excite different actions in the stomach and system, in consequence of which NEW, or MODIFIED RESULTS are produced. B.—By combining substances which have the property of acting CHEMICALLY upon each other; the results of which are— I a. The Formation of New Compounds. K b. The Decomposition of the Original Ingredients, and the developement of their more active elements. C.—By combining Substances, between which no other change is induced than a diminution, or increase in the Solubility of the principles in which their Medicinal virtues reside. L a. By the intervention of Substances that act CHEMICALLY. M b. By the addition of Ingredients whose operation is entirely Mechanical.
