* That after the completion of every three hours' trituration of a medicinal substance, the mortar, pestle and spatula are to be several times scalded with boiling water, being after every scalding wiped quite dry and clean, I presuppose as indispensable, so that no idea of spoiling any medicine that may be triturated in it in future may be entertained. If the further precaution is used of exposing mortar, pestle and spatula to a heat approaching red heat, this will dissipate every thought that any least rest of the medicine last triturated can cling to them, and thus even the most scrupulous mind will be satisfied.
* Vegetable substances which can only be procured dry, e, g.,cinchona bark, ipecacuanha, etc., are prepared by the same kind of trituration and will completely dissolve when potentized a million fold, not less, with their peculiar powers, in water and alcohol, and may then be preserved as medicines far more easily than the easily spoiled alcoholic tinctures. Of the juiceless vegetable substances, such as oleander, thuja, the bark of mezereum, etc., we may, without making a mistake, take of each about one and a half grains of the fresh leaves, bark, root, etc., without any further preparation, and triturate the same three times with 100 grains of sugar of milk to the millionfold powder trituration. A grain of this dissolved in alcohol and water may be developed in the diluting vials with alcohol to the necessary degree of potency of their powers by giving for each potency two succussive strokes. Also with the freshly expressed juices of the herbs it is best to at once put one drop of the same with as much sugar of milk as is taken for the preparation of the other medicines, so as to triturate it to the millionfold powder attenuation, and then a grain of this attenuation is dissolved in equal parts of water and alcohol, and must be potentized to a further dynamization through the twenty-seven diluting vials by means of two succussive strokes. The fresh juices thus seem to acquire more of dynamization, as experience teaches me, than when the juice without any preparation by triturating is merely diluted in thirty vials of alcohol and potentized each time with two succussive strokes.
* Even phosphorus which is so easily oxidized by exposure to the air is potentized in a similar manner, and thus rendered soluble in these two liquids, and is thus prepared as a homoeopathic medicine; but in this case some precautions are used, which will be found below.
* Only phosphorus needs some modification in the preparation of the first attenuation to the 100th degree. Here the hundred grains of sugar of milk are at once put into the triturating bowl and, with about twelve drops of water, they are stirred by means of the wet pestle into a thickish pap; one grain of phosphorus is then cut into numerous pieces, say, twelve, and kneaded in with the moist pestle and rather stamped than rubbed into it, while the mass which often clings to the pestle is as often scraped into the mortar. Thus the little crumbs of phosphorus are rubbed to little invisible dust particles in the thick pap of sugar of milk even in the first two periods of six minutes each, without the appearance of the least spark. During the third period of six minutes the stamping may pass over into rubbing, because the mass is then approaching the form of powder. During the succeeding three periods of six minutes each the trituration is carried on only with a moderate force, and after every six minutes the powder is scraped from the mortar and the pestle for several minutes, which is done easily, as this powder does not adhere tenaciously. After the sixth period of trituration the powder, when standing exposed to the air in the dark, is only feebly luminous, and has but a slight odor. It is put into a well stoppered vial and marked phosphorus /100, the other two triturations /10000, and 1/mill. are prepared like those from other dry medicinal substances.
To potentize the substance to the ten thousandth attenuation, one grain of the powder last mentioned as being the one hundredth is taken with one-third of 100 grains of fresh sugar of milk, stirred in the mortar with a spatula and treated as above, so that every third is triturated twice for six minutes at a time, and after every trituration is scraped together (for about four minutes), before the second third of the sugar of milk is added, and after this has been similarly treated the last third of sugar of milk is stirred into it and again similarly triturated twice for six minutes at a time, when it is scraped together, put in a stoppered vial with the signature /10000 as it contains the medicine potentized to the ten thousandth attenuation.*
The same is done with one grain of this powder (marked /10000) in order to bring it to I, and thus to attenuate it to the millionfold potency.
In order to produce a homogeneity in the preparation of the homoeopathic and especially the antipsoric remedies, at least in the form of powders, I advise the reducing of medicines only to this millionth potency, no more or no less, and to prepare from this the solutions and the necessary potencies of these solutions; this has been my own custom.
The trituration should be done with force, yet only with so much force that the sugar of milk may not be pressed too firmly to the mortar, but may be scraped up in four minutes.
* Thus it will be seen that every attenuation (that to /100, that to /10000. and also the third to /1000000 or I) is prepared by six times triturating for six minutes and six times scraping together for four minutes each time. Thus each one requires one hour.
Now in preparing the solutions * from this, and in bringing the medicines thus potentized one million-fold, into the fluid form, (so that their dynamization may be still further continued), we are aided by the property of all medicinal substances, that, when brought to the potency I, they are soluble in water and alcohol; this property is still unknown to chemistry.
