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

(Arbor vitoe.)

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

(The green leaves of the Thuja occidentalis are first bruised to a fine pulp themselves, then stirred up with two thirds of their weight of alcohol, and the juice then expressed.)

No serious medicinal employment has been made in Europe before now of this plant, which somewhat resembles in external characters the Juniperus sabina; for what PARKINSON and HERRMANN say of it is evidently more theoretical speculation, after the fashion of the dear old Therapia generalis. According to BOERHAAVE its distilled water has been found useful in dropsical diseases. According to KALM it is popularly employed in North America as an external remedy in some undefined pains of the limbs.

The following elements of artificial diseases, the pure effects of this uncommonly powerful medicinal substance, with be regarded by the homoepathic practitioner as a great addition to his medicinal treasury, and he will not fail to make a useful application of them in some of the most serious diseases of mankind, for which hitherto there has been no remedy. For example, he will perceive from these symptoms that the juice of thuja must be specifically useful in that hideous disease arising from impure coitus, the fig-warts, if they be not complicated with other miasmata; and experience also shows that thuja is the only efficacious remedy for them. And for a similar reason it most certainly cures that bad kind of gonorrhoea resulting form impure coitus if it be not complicated with other miasmata.

I employed the decillion-fold dilution of the juice, in the dose of a very small portion of a drop, even in the worst cases.

As the fig-wart gonorrhoea is one of the few permanent miasmatic diseases, I was able to test in the most certain manner the degree of efficacy of the higher dilutions of thuja juice. Thus I found that even the higher dilutions. e.g. the decillion-fold or even the vigesillion-fold dilution (1/xx), made with sixty diluting phials, each of 100 drops), if each diluting phial were successed ten times and oftener (that is, with ten or more shakes of a powerful arm), was not weaker in power than the less diluted preparations, nor, on account of the enormously diminished arithmetical fraction, had it sunk to complete powerlessness, to nothing, but, on the contrary, it had rather become even more intensely charged (The discovery that crude medicinal substances (dry and fluid) unfold their medicinal power ever more and more by trituration or succession with non-medicinal things, and in greater extent the further, the longer, and the stronger this trituration or succussion is carried on, so that all their material substance seems gradually to be dissolved and resolved into pure medicinal spirit; – this discovery, unheard of till made by me, is of unspeakable value, and so undeniable, that the unheard of till made by me, is of unspeakable value, and so undeniable, that the sceptics, who from ignorance of the inexhaustible ersources of nature in the homoeopathic dilutions, see nothing but mechanical division and diminution until nothing remains (therefore, annihilation of their medicinal power), must see their error as soon as they appeal to experiment.) with the medicinal virtue of thuja.

Innumerable accurate trials have so completely confirmed this (also with regard to other high fluid medicinal dilutions prepared in a similar way) that I can certify to its truth form conviction.

In order to obtain real preparations of sufficiently developed, but at the same time suitably moderated. Power for even the more and most sensitive patients by the dilutions of medicinal substances for homoeopathic use, for some time back I have adopted the plan in the case of all fluid medicines of succussing each diluting phial with only two strokes of the arm.

The duration of the action of even the smallest doses is nearly three weeks.

Camphor appears to be the best antidote to mitigate the excessive action of this juice in larger doses.

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.
