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

(From vol. iv, 2nd edit., 1825.)

(The alcoholic solution of the inspissated juice of the West Indian tree Guanicum officinale, which consists chiefly of resin..)

The homoeopathic physician will find even in these few symptoms a sufficient guide to enable him to make a sure curative employment of this vegetable substance in morbid states for which it is suitable by similarity, and to prevent him from being misguided by the vague and misleading recommendations of it in gout and rheumatism by the imaginary name of a disease, instead of attending only to the similarity of the symptoms of the disease to be cured on the one hand, with those of the remedy on the other.

One drop of the alcoholic tincture stirred u[ in one ounce of water, in which the small quantity for a reason it contains is completely dissolved by shaking, is quite sufficient for a dose; in some cases, indeed, I will be found rather too strong.

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.
