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

(Animal charcoal.)

(In order to prepare animal charcoal, thick piece of ox-leather is placed among red-hot coals, and allowed to burn until the last flame has completely expired, and then the red-hot piece of leather is quickly placed betwixt two stone plates, so as to extinguish it immediately, otherwise it could continue to smolderin the air, and thus dissipate the greater portion of its charcoal. A grain of this is triturated with 100 grains of milk-sugar in a pocelain mortar for an hour (every ten minutes being divided between six minutes of trituration and four minutes of scraping); of this product one grain is again triturated in a similar manner with 100 grains of milk-sugar, and of the powder thus made one grain is again triturated for an hour in the same manner with 100 grains of fresh milk-sugar, in order to produce the million-fold potentized attenuation of carbo-animalis.)

Although the animal charcoal presents so much similarity in its effects on the human health to the vegetable charcoal, yet there are so many differences from the latter in it, and so many peculiar symptoms, that I consider it useful to record here what I have observed from it.

Some symptoms were observed by a Russian physician, Dr. Adam; these I have indicated by the letters Ad.

A very small portion of a grain of the million-fold (1/1) pulverulent attenuation is usually quite sufficient for a dose and acts for at least three weeks in chronic diseases. Camphor proved itself an antidote and alleviating remedy for its too energetic action in highly sensitive persons.

[ Beside ADAM, above mentioned, HAHNEMANN got a few symptoms from WEISE in Rust’s Magazin f. d gesammte Heilk., vol. xxii. This medicine makes its first appearance in the 2nd Edit., where its symtpoms are 191; in the Chr. Kr. there are 728, 214 of these being selected from the 254 symptoms in HARTLAUB and TRINKS”S R.A.M.L., and 23 contributed by WAHLE.]

Vertigo: towards evening (7 o’clock) when she raised up her head all went round in a circle with her; she must always sit in a stooping posture, and when she rose up she staggered to and fro; she felt dull in the head and as if all objects moved; while lying all night long she felt nothing of it – but did so in the morning again on getting up.

(The author prepared his animal charcoal in rather a differet manner.He took any kind of flesh freed from fat, added one third by weight of bone to it, and roasted the mixture in an ordinary coffee roaster.)

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.
