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

(From vol. i, 3rd edit., 1830.)

(The fresh expressed juice of the tops of the floweringmale or female hemp-plant, mixed with equal parts of alcoho, and after standing some time the clear supernatant fluid decanted off.)

Hitherto only the seeds, generally (rubbed up with water) as emulsion, or decoction, have been used with advantage in the inflammatory stage of gonorrhoea, and in ancient times (by DODONAEUS, SYLVIUS, HERLIZ) in some kinds of jaundice. In the former case of the homoeopathic reason observed in the urinary organs after the administration of hemp to healthy persons, although no physician ever recognized this. The plant itself has only been used as a domestic remedy, but it was much employed in Persian country inns in order to relieve the fatigue of pedestrian travellers (CHARDON, Voyage en perse), for which it is truly homoeopathic as the following cannabis symptoms (269 to 275) demonstrate.

But we may employ the juice of hemp for curative purposes of much more importance in various diseases of the genital organs, of the chest, of the organs of the senses, &c. for which the following observations present the homoeopathic indications.

For a long time I employed the undiluted alcoholic tincture of cannabis, in the dose of the smallest portion of a drop; but the higher and the very highest yet made dilution and potency (X) of it develops the medicinal powers of this plant in a much greater degree.

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.
