Hahnemann’s proving symptoms of homeopathy remedy Muriaticum Acidum from Materia Medica Pura, which Samuel Hahnemann wrote between 1811 to 1821…

(Muriatic acid.)

(From vol. v, 2nd edit., 1826.)

(It should be carefully freed from the sulphuric acid often mixed with it, by means of re-distillation over the chloride of sodium, or (better) it may be precipitated by muriate of baryta, and, after being thus freed from the sulphuric acid, redistelled.)

For medicinal use one drop of it is first diluted by means of too succussion with 100 drops of diluted alcohol (made of equal parts of distilled water and strong alcohol taken together ten time), and of this one drop is to be twice successed (with two strokes of the arm) with 100 drops of undiluted alcohol (1/10000th), and then of this one drop is to be again twice shaken with 100 drops of alcohol (1/1). One globule the size of a poppy of a drop, for with one drop 200 such globules are sufficiently moistened. Yet this million-fold dilution, although administered in such a small volume, will be found in many cases to be still too powerful when muriatic acid is homoeopathically indicated, because this medicine possesses a high degree of efficacy.

Although a tolerably homoeopathic employment in suitable morbid states can be made from the following observed alterations in the healthy, yet it would be desirable to possess a more complete proving of it as to this pure effects.

Samuel Hahnemann
Samuel Hahnemann (1755-1843) was the founder of Homoeopathy. He is called the Father of Experimental Pharmacology because he was the first physician to prepare medicines in a specialized way; proving them on healthy human beings, to determine how the medicines acted to cure diseases.

Hahnemann's three major publications chart the development of homeopathy. In the Organon of Medicine, we see the fundamentals laid out. Materia Medica Pura records the exact symptoms of the remedy provings. In his book, The Chronic Diseases, Their Peculiar Nature and Their Homoeopathic Cure, he showed us how natural diseases become chronic in nature when suppressed by improper treatment.
