§ 275
The suitableness of a medicine for any given case of disease does not depend on its accurate homoeopathic selection alone, but likewise on the proper size, or rather smallness, of the dose. If we give too strong a dose of a medicine which may have been even quite homoeopathically chosen for the morbid state before us, it must, notwithstanding the inherent beneficial character of its nature, prove injurious by its mere magnitude, and by the unnecessary, too strong impression which, by virtue of its homoeopathic similarity of action, it makes upon the vital force which it attacks and, through the vital force, upon those parts of the organism which are the most sensitive, and are already most affected by the natural disease.
