Machine-Made Potencies History

[Robert Muentz]

Since homoeopathy was developed by H. hardly anything has changed in principle. The Law of Similars, the development of remedies based upon healthy people and the Theory of Dosage have remained unchanged and still provide the basis of the therapy. However, homoeopathy has been extended by the use of remedies with degrees of dilution exceeding H.’s by far. No remedy higher than C30 has been found in H.’s estate.

Even though he always spoke of remedies potentized up to C30, he did not rule out the possibility of using higher dilutions on patients as well. For him the only parameter to do so was his experience with patients. “It is only experience that can decide whether this tiny particle has become too weak to fight an illness, too weak to turn illness into health in this particular case. This is no matter of consideration based on theories but a matter of experience which is the only competent judge to make a decision.”

This consideration made other homoeopaths deal with high potencies in more detail, manufacture them and test them in therapy.

 

The C200- Remedies

Still in the days of H., Clemens F.M. von Boenninghausen (1785-1864) potentized remedies up to C200. In 1859 he wrote, “Just like allopathy, which used experience - because experience is the one and only means of deciding i.e. knowing to which degree the dose can be increased safely, homoeopathy also relied on experience to find out up to which amount the dose could be reduced to still have a healing effect.”

Boenninghausen also motivated Lehrmann, another of H.’s students, to manufacture C200 potencies following H.’s method. At each step Lehmann shook the vial vigorously 25x.

After all, the reason for using higher and higher potencies was the desire to reduce the initial aggravation of symptoms, which occurs in the course of any homoeopathic treatment. Before long it was realized that this goal could not be reached, but that a new effect occurred with these remedies:

The period of action was extended considerably and the remedy then developed effects which had been hidden in the range of lower potencies.

 

Julius Caspar Jenichen

Jenichen was introduced to homoeopathy by H.’s student Gustaf Wilhelm Gross. He was one of those manufacturers who produced the first high potencies by hand. He was of the opinion that the shaking strokes in particular were responsible for the different potency levels of the remedy. For a long time he kept his method a secret because he wanted to manufacture high potencies of his whole stock of remedies and test them in therapy before publicizing his theory. This way of doing it was criticized by numerous of his contemporaries, but finally Berridge found out about the secret:

Jenichen started with the C29, he let the contents evaporate and thereafter refilled the vial with ethanol. Then he shook it using 12 shaking strokes for each potency step. The first 800 steps were diluted in a ratio of 1:300 and shaken 12x each, then the ratio was 2:12,000 and the vial was shaken 30x.

 

This method led to the development of various potentizing machines. Since the construction of such machines was based upon different attempts and considerations the results were similarly divergent.

 

Like the potentizing machines of those days, today’s potentizers also share the principle that only one vial is used for potentizing. At that time this single-vial method using the centesimal scale developed by Count Korsakoff , represented a revolutionary divergence from H.’s potentizing method. There is no evidence however, in reports of the year 1829 based on personal contacts with Korsakoff , that H. criticized this method.

Should a 10M be prepared today using the multi-vial method, the cost of the vials and tops alone would amount to approximately EUR 2180.- These vials would cover a surface of about 10 square metres if set down close to each other and would have to be disposed of after single use. This pioneering work also showed the homoeopaths of that time, that it was not only possible to prepare higher potencies than H.’s C30 remedies, but also to increase their efficacy by doing so. Then it was only a short step towards potentizing higher dilutions by machine. Mure broke the ice and built

the first potentizing machine.

 

Potentizing by Machine

There are basically two types of potentizing machines: Fluxion potentizers, which potentize using turbulence in liquids, and succussion potentizers, which use shaking strokes for potentizing. In the case of fluxion potentizers, which work discontinuously, the vial is repeatedly filled and emptied (Skinner, Boericke, Kent); The continuous method measures the potency level from the amount of medicine carrier continuously passing through (Swan, Allen, Fincke). Due to the wide dissemination of the fluxion method at the turn of the century most case studies are about remedies manufactured in this way.

 

Benoit Mure (1809-1858)

A contemporary of H. is likely to be the first who built potentizing machines. It was in Palermo in 1838, when he constructed 3 machines for the manufacture of homoeopathic remedies using the succussion method.

So far no comment by H. on their efficiency has been known, neither were those remedies to be found in H.’s pharmacy in Paris.

In the year 1865, B. Fincke published a paper on the invention of his potentizing machine with which he produced fluxion potencies. Earlier he had dealt with mechanical potentizing in a series of preliminary experiments, where he tried to use the force of a steel spring under tension. With his fluxion potencies, Fincke was also the first manufacturer who prepared far higher dilutions than C200.

The first machine, which he used until 1869, consisted of a thin tube, a glass and a graduated vessel. Tap water flowed through the tube into the vial. From there the water flowed into the measuring vessel whose graduation showed the respective potency level. With this system Fincke produced rather irregular potency levels such as 16C, 11M, 19M, 23M, 37M, 47M, 103M etc.

In the course of time the inventor started doubting the efficiency of his method:

By injecting the liquid into the potentizing vial the remedy could easily be soiled.

The uncommon range of potency levels

The measuring of potency levels based upon the water passing through

In 1869 he therefore disposed of all his remedies prepared up to then and developed a machine with which he manufactured his well-known “Fincke High Potencies”: There it was essential to measure the volume of the medicine carrier before it would flow into the vial. As he had his machine patented in 1869, it was not possible for a long time to find out closer details on the method of potentizing. Kent, however, reported on their properties, “The Fincke High Potencies never failed me; they act quickly, long and deeply”.

 

Fincke writes about his method, “It differs in many respects from the other methods known - but in one essential point the Hahnemanian mode of preparation has been preserved and perfected, and that is by adhering rigidly to the centesimal scale.”

And exactly there he was mistaken, because his method differed considerably from H.’s multi-vial method. He used the continuous method where the glass is continuously passed through, thus “steps” were simply out of the question. He did not use lactose for the trituration of the basic substances, because he thought it would have too much medicinal efficacy itself. Ethanol would evaporate too quickly and therefore increase the potency level unintentionally. Moreover, it would be too expensive because for a Fincke CM 5000 Drachmen ~ 17kg ethanol (1 Drachme = 3 Scrupel = 3.888g) would be needed. He manufactured the initial potencies up to C30 with ethanol, then he worked with distilled water, which he soon replaced by Nassau-water from Brooklyn, i.e. tap water from his surgery, which was the cheapest way.

The increasing success of his remedies was proof of his theory that by potentizing a C30 the spirit of the remedy becomes an integral part of the carrier to such an extent that it cannot be destroyed by external influences.

Thus he was of the opinion that possibly existing contaminants in the Nassau-water would not influence the efficacy negatively. “Each water has an individuality of its own that does not interfere with the action of high potencies in using it as vehicle for potentization.”

When potentizing the first steps, Fincke diluted with ethanol in a ratio of 1:100 and shook the vial 180 times in dactylus rhythm. Then he emptied the vial with two vigorous downward strokes and refilled the vial with 99T ethanol. In case of watery remedies he potentized up to C6 using this method and in case of fatty remedies, up to C30, which now represented his “initial potencies”.

Now he continued working with the apparatus depicted above. It consisted of a stock vessel (500ml, 5l or 20l) with graduations. A glass tube was placed inside which extended to the bottom of the bottle and rose out of the bottle ending in a U-bend. It was used for emptying the bottle. It stretched beyond the bottom of the bottle by approximately 2.5cm and a rubber tube connected it to the regulator, a glass tube tapering considerably at its end. This tube stretched to the bottom of the vial which was set in a wooden holding device on a draining channel. When starting, the outlet was filled with water from the stock vessel, the regulator tube was connected and put into the vial moistened with “initial potency”. When the potentization had been completed, Fincke emptied the glass with two vigorous shaking strokes and refilled it with 95% ethanol. After that he vigorously shook it 2x in dactylus rhythm. He sealed the vial with a cork and labelled it as follows:

6 cm Aconitum napellus.

? (F flor.rec.) 1871

The square root sign stands for “parent substance”, F for “tinctura fortis” = original tincture, “Flor.rec.” stands for fresh plant. Fincke also took down the place where the plant had been collected.

He manufactured the last remedy in 1905.

His remedies were always administered as globules.

In an article on the manufacture of high potencies Adolph Lippe wrote in 1868, “Lehrmann’s 200th potencies act very similarly to the 30th of H., Jenichen’s act much more intensely, and Fincke’s far surpass them as to intensity.”

With his method Fincke caused a sensation. In 1941 W.W. Robinson stated, “The discovery by Fincke that the “fluxion” or continuous flow of water through a receptable holding a fixed quantity, enabled attenuations to be prepared without succussion and produced wide contention on the part of those who saw in such an accomplishment a radical divergence from what had long been accepted as an indispensable part of the attenuating procedure.

But whatever the opinions, the fact remains that machines for making high attenuations became a reality and the reports of their clinical application were uniformly satisfactory.”

 

Dr. Lenth was the next to produce high potencies. He, however, never gave away his method and his remedies never gained any importance, either.

 

Caroll Dunham. (1828-1877)

 

Thomas Skinner (1825-1877)

Born in Newington, Edinburgh, Scotland. There he studied medicine and graduated from university in 1853. In the following years he developed the Skinner-Mask, which proved to be a great success in the field of anaesthesia. After a fit of influenza he suffered from insomnia in 1871 and could not sleep for more than 2 hours per week. Two years later he met Dr. E.W. Berridge,

who was on his way from England to Pennsylvania to study homoeopathy at the H. Medical College. He prescribed a single dose of Sulfur MM prepared by Boericke for Skinner, who was cured immediately. From then on Skinner was an advocate of homoeopathy.

In 1876 he came to the U.S. to attend the International Congress on Homoeopathy of the American Institute of Homoeopathy, chaired by Dr. Caroll Dunham. There he met all the important figures of his time, such as Hering, Lippe, HC Allen and Samuel Swan.

In 1878 Dr. Thomas Skinner developed the fluxion-centesimal potentizer, which was constructed to be placed on a small washbasin. It was powered by water and two vials were used for potentizing, one of which only served as a spare.

The potentizing principle was the powerful flow of medicine carrier into the solution of the remedy. The water (simple tap water) was flowing out of a phosphorus-bronze nozzle, and the flow could be regulated. The machine was started up in the following way:

The potentizing vial was filled with the remedy to be potentized and shaken about 1 minute in order to moisten the wall. Then the vial was emptied with several downward strokes and attached to the holding device. After that the machine was started up and at each step 100 drops were injected into the vial which was emptied thereafter by swivelling the holding device. When the desired potency level had been reached, the vial was emptied into a new vial, this was emptied again and refilled with ethanol. Then it was shaken vigorously 25 times and thereafter crude globules were moistened. The remedies were specified as FC (Fluxion Centesimal) to distinguish them from H.’s centesimal potencies. Skinner always emphasized the discontinuity of his method in contrast to Swan’s and Fincke’s methods.

Skinner said about his machine, “It passes through 50 centesimal steps per minute, 3,000 per hour, 72,000 per day, 100,000 per about 33 hours and M in about 14½ days.” In his letter to Dr. Hayes, James Tyler Kent states that according to him, Skinner’s machine is the only one in the world which manufactures high-quality remedies.

Shortly before the turn of the century Boericke & Tafel’s Philadelphia-based company “Penn Instrument Company” launched an advanced version of Skinner’s centesimal potentizing machine.

The machine is set in a case with sliding doors of glass and has six holding devices for vials attached to one girder. Each vial in the case is separated from the others by a special partition, so that the remedies cannot contaminate each other. With an adjustable syringe the water is injected into test tube-like vials containing the remedy. Then the vials are tilted and emptied. One cycle takes about one second.

In retrospect one can say that Skinner’s remedies were the most widely used among the high potencies. Around 1960 there was no manufacturer in the USA who potentized remedies higher than C200. When buying a high potency then, it was most likely one from Boericke & Tafel, i.e. one from a Skinner potentizer.

Until recently homoeopaths wrongly believed that Skinner remedies, as advertised by Boericke & Tafel, were potentized using shaking strokes. Only when the attempt was made to include the machine as a standard method in the American Pharmacopoea HPUS, did this error become obvious. Since then these remedies have been less popular in the USA because they differ too much from H.’s method of diluting and shaking. Moreover, it turned out in the course of experiments with perfect copies of the Skinner potentizer, that it was not one hundredth of the remedy, as assumed, that remained in the vial, but only about one seventeenth.

 

James Tyler Kent (1849-1916)

Only a couple of years later Kent constructed his own potentizing machine, which was used for the manufacture of remedies by Erhart and Karl in Chicago. This machine potentized up to CM, and

it was the only one where the liquid was shaken at each step. Moreover, Kent used filtered water as a medicine carrier, contrary to all other manufacturers who used simple tap water.

The machine had an engine driving two arbors connected with a worm gear pair. Attached to these arbors, there were eccentric plates for the strokes, the opening mechanism and the lifting mechanism. Urban J. Erhart’s manually potentized C1000 served as the basis. During the potentizing process both vials were sealed with a leather membrane, which was lowered after each completed step, so that the contents of the vial could drain off. Unfortunately, there is no information on the way in which the empty vials were refilled with water. There are no contemporary witnesses either. It is regarded as unlikely that Kent only used a flexible tube and gravity to supply the system with water.

In Erhart & Karl’s list, 900 Kent remedies in the potencies 10M, 50M and CM were offered, prices of 1 oz were 1.00, 1.50 and 2.00 dollars.

 

H.C. Allen (1835-1909)

The fluxion-centesimal-potentizer of the homoeopath born in Quebec, used Kent’s CM and potentized by injecting water into a round medicinal vessel which had been manufactured by Kent himself. When the highest potency level of DMM had been reached, the vessel was disposed of, so that it could not be reused accidentally. Several tubes rose down into the vessel. They pressed the water against the glass bottom in different angles, thus creating turbulence in the liquid, which then moistened the whole surface of the vessel. The glass vessel itself was clamped to the holding device so that the high water pressure could not destroy it. Moreover, a water filter, an engine and a water meter were connected to this machine. Unfortunately, no illustration of this potentizing machine has been handed down. In Erhart & Karl’s list of remedies 250 polychrests are listed. Their potency levels were DM, MM, CMM and DMM at prices of 2.00, 2.50, 3.00 and 3.50 dollars.

 

S.P. Burdick

The machine, as depicted, was described in an article in the North American Journal of Homoeopathy in the year 1879. Martin Deschere called it the first construction which was in complete accordance with the centesimal principle.

In practice, however, the high potencies which had been prepared using this machine did not seem to have proven their worth, since neither details on the whereabouts of the machine, nor on the efficacy of the remedies have been handed down.

 

Francis Edmund Boericke (1826-1901)

He was born in Glachau, Germany, and emigrated to the USA in 1849, where he met Rudolf Tafel. In 1863 he completed his medical studies at the H. Medical College of Pennsylvania. In 1878 he published an article on a potentizing machine constructed by him. It was operated with a crank which pumped water into a medicinal vessel via a system of pistons. After five strokes the vessel was emptied. Skinner supposed that Boericke’s bad health was caused by the continuous influence of high potencies on his body during manufacture.

 

Ellis M. Santee

In 1889 the young doctor Dr. Santee constructed a potentizing machine at the H. College in Philadelphia, which was so simple, that using it each doctor could prepare his own remedies in his surgery. The machine was in a sort of suitcase, which was small enough to be placed on any washbasin in a surgery. The feed tube was first connected to a water meter, which at the same time served as a potency level indicator, and then to a nozzle. The medicine carrier water passed through the 30 openings of the nozzle, thus swirling and diluting the remedy in the vessel. When enough liquid had passed through, the vessel was tilted by gravity and emptied. This procedure was repeated again and again. According to records, J.T. Kent also used such a machine for some time.

 

Samuel Swan (1813-1893)

Swan turned to homoeopathy later in life and was known for his numerous self-made remedies, among them Lac defloratum, Medorrhinum, Tuberculinum and Syphillinum.

For potentizing he piped a continuous stream of liquid into a vessel which had once contained a drop of medicinal substance. He measured the height of the potency from the amount of water passing through.

Lippe called him a “bottle-washer” and Kent wrote in 1903, “Swan’s potencies are a deception of the worst kind. I have seen how he prepares them and have then thrown away all of my Swan potencies.” After the death of the so-called constructors, potentizing by machine came to a temporary end. Erhart and Karl kept distributing the remedies from the Kent and Allen machine until 1940.

 

Decimal Potencies - the Countermovement

The time of the development of machine-made high potencies was accompanied by fierce controversies between the homoeopaths. This, however, induced the supporters of high and low potencies to go their own ways.

The decline of homoeopathy in the USA also resulted in a decrease in demand for high potencies and the manufacturers again turned to remedies in the low potency range.

Thus, it was Constantine Hering in Philadelphia who responded to the increasing demand for low potencies by introducing decimal triturations, whose principles were publicized by Vehsemeyer in Berlin and shortly after were also mentioned in Gruner’s and W. Schwabe’s pharmacopoeias. Vehsemeyer introduced D-potencies because they could be dosed precisely. He thought that the C3 of a remedy would already be too strong if the C2 did not act.

He suggested solving the problem of dosing by using the finer gradation of the decimal range. That is to say he paid special attention to the efficacy of the substance, whereas H. regarded the centesimal potencies as being too strong and therefore developed the Q-potencies (50,000th series), which acted less powerfully and could be dosed better.

Multi-vial versus single-vial

For preparing homoeopathic potencies by machine, it is nowadays considered indispensable to use the single-vial-method according to Korsakoff. Changing the potentizing vial after each step would not only be too complicated from a technical point of view, but also too costly.

The question of the correct specification of machine-made high potencies has been discussed repeatedly, whereas their efficacy in therapy has been of lesser interest. (30). Mathematically speaking, the final dilution of a Korsakovian potentization is identical to that of the Hahnemanian multi-vial-method, provided that one hundredth of the remedy solution keeps adhering to the glass wall. In practice, however, small tolerances in machine adjustments and adsorptive phenomena have a great influence on the degree of dilution of the remedy.

In experiments with eosin, which was potentized up to C6, C15, C30, C200, 1M, 10M and 50M in different potentizing machines, Boericke & Tafel tested the accuracy of Swan’s, Skinner’s and Fincke’s systems in 1906. Using a spectrometer, they found out that the dilution level of Skinner remedies amounted to only a 5th of the dilution levels of remedies prepared using the Hahnemanian multi-flask method, a C30 thus approximately corresponded to a C6.

This is also in accord with current experiences made with such remedies. On the occasion of the annual general meeting of the Ã-GHM in 1999 Dr. Reinhard Flick stated that Müntz’s fluxion potencies act more shortly and less powerfully than C- and K-potencies. The low potency levels (FC500 und FC1M) in particular act very gently and hardly ever provoke an initial aggravation of the symptoms.

 

The power of a FC500 approximately corresponds to a Hahnemanian C30, the FC10M approximately to a C200 and the FC50M to a C1000. Dr. Flick summarized that homoeopathic treatment starting with the FC10M is successful in most cases and that the FC50M is also suitable for the beginning if the symptoms are very clear.

 

The Accuracy of the Korsakovian Method

Korsakovian potentizing which is used for all discontinuous potentizing machines is often regarded as identical to the multi-vial method regarding its accuracy. In order to assess the accuracy of the dilution ratio of the Korsakovian method, Mag. Renee Fikisz made a statistical evaluation. (34) The analysis was carried out with potentizing vials of different sizes. Two thirds of each vial were filled with the medicine carrier water. Then, as in homoeopathic potentizing, the vials were shaken ten times and emptied with two vigorous downward strokes.

Definitions, interpretation and evaluation

Mean value:

The arithmetical mean shows the residue which on average remains in the individual vials after they have been emptied. As expected, it is increasing with the increasing inner surface of the vial. It is worth mentioning the fact that the calculated average residues are in all cases considerably higher than the residues required for centesimal potentizing (0.07ml / 0.15ml / 0.20ml). The adaptation of these mean values to the required mean value increases significantly with the increasing size of the vials.

Standard deviation and variance:

The empirical standard deviation is the most commonly used variation measure. It shows the average deviation of the measured values from the mean value, thus describing the reliability of the method to reach the mean value (mean variation). Since in our case plain numbers lack meaningfulness - different vial sizes are compared to each other - the standard deviation was compared to the mean value and the relative standard deviation was calculated. Thus, it could be demonstrated that when using 20ml vials the residues deviated from the mean value only by ±8,59% on average.

The empirical variance (average square deviation) in this case also has the best value.

Probability ranges

Assuming that the values of the individual series of measurements are distributed according to the Gaussian law, the probability of further measured values can even be predicted (probabilities and corresponding value intervals see table).

Evaluation

The high degree of deviation from the required mean value excludes the use of 10ml vials. The use of 30ml vials provides better results regarding the approximation to the required mean value, on the other hand, mean variation is getting worse.

A possible compromise between both tendencies could be the use of 20ml vials for Korsakovian potentizing. The results showed surprisingly great deviations from the value 1/100, which is referred to in publications beginning with Korsakoff.

 

Müntz’s Korsakovian Potentizing Machine

It was a school project of the technical college of Eisenstadt. The goal of the project was the development and construction of a machine for the manufacture of high potencies, with dilutions up to MM. The manufacture of reliable and powerfully acting Korsakovian potencies, required a high constancy of both the intensity of the strokes and the dilution ratio, which induced the author to commission the HTBLA-Eisenstadt (technical college) with the construction of a machine for all-automatic potentizing.

 

The following requirements were made:

    The dilution is potentized with ten strokes.

    The intensity of the strokes shall be equivalent to that reached by a strong man’s arm.

    The potentizing machine shall be able to produce ten remedies simultaneously.

    The remedies must not be exposed to any magnetic stray fields.

    The system shall be automatically controlled by a PC.

    In case of a power failure or other faults all data have to be saved fail-safe.

First of all, several different solutions for the realization of a potentizing machine were developed. After systematic evaluation the best concept was chosen. It served as a basis for the construction

of the machine, which was then realized on the CAD-system of the school. The first step was the development of the individual sets of components, which were then assembled. While the shop drawings of all components needed for the construction of the machine were being made, control diagrams, circuit diagrams and the respective software for the control system were being developed.

Before long it turned out that only compressed air could be used as driving power.

 

Description of the individual sets of components:

Set I - FRAME

As all the other components are mounted on this frame, this set is an essential part of the potentizing machine. It is mainly responsible for reducing part of the vibrations and for providing a stabile basis for the whole machine.

The frame is carried on wheels so that the machine can be transported easily.

Set II - DOSING

The main function of this set is to fill an amount of 4.0ml of water into each of the ten vials by compressing the pump hose with an adjustable thrust piece.

Two reflux valves ensure that the water is pumped into the right direction and that the dosing system is always full. There are 10 of these dosing systems which are connected to each other by a dosing girder. With the extension of the pneumatic cylinders, all 10 thrust pieces are moved via the dosing girder. As required, each of the 10 systems can be activated or deactivated by operating

the spherical buttons.

Set III - Main body

It has the following functions:

Guidance of the vial during the shaking process

Absorption and reduction of the vibrations

The centre of this unit is a granite block of 85kg with ten bore holes for the guide tubes where the vials are exposed to the strokes.

The momentum of undamped strokes would destroy the vials immediately. That is why a special damping material was inserted at the bottom of each unit. The granite block was separated from

the frame by rubber dampers in order to prevent the checkless transmission of the vibrations of the whole system to the periphery.

Set IV - Shifting device

Changing position

On this illustration the guide tubes with the potentizing vials are freely accessible in the upmost position. The whole shifting device is in the backmost position. A new sterilized vial is filled with

a C200 which has been potentized by hand using the multi-vial method and is then put into the holding case.

Suction position

The suction tube of the shifting device is moved above the vial. Then the suction unit is lowered till the suction tube touches the bottom of the vial and the liquid is sucked out of the vial. The residues of the liquid adhering to the glass wall remain inside and serve as the basis for the next step. After suction has been completed the suction unit moves back to the filling position. The phases are repeated as often as required.

Filling position

The shifting device now moves from the vial changing position to the foremost position so that the feed tube is above the vial. Then 4.0ml of water are filled into the vial.

Shaking position

The shifting device now moves in a way that the shaking unit is positioned above the vial. After that the U-steel is lowered and puts the stopper onto the vial, simultaneously the spring is bent.

By opening a valve, the overpressure in the guide tube is removed abruptly and the vial is hurled downwards. Then the guide tube is again filled with compressed air and the process can start anew. The intensity of the strokes can be adjusted with the spring. When the required number of strokes has been reached (normally 10x), the U-steel moves back in the upmost position.

PC-control

The controlling system should control and monitor the process automatically and take respective measures in case of failures and faults that may occur.

In case of a power cut, the last counts of the counter are saved, so that the process can be continued later. The medicinal liquid shall not get close to electric or magnetic fields.

Moreover, the system is responsible for documenting the potentizing processes.

Properties of the controlling system

The system is controlled by a PC which is connected to the sensors and actuators via a 48-channel I/O-card from BMC. The PC-control uses the normal Windows user-interface because of its user-friendliness. A special software for the control of the machine was developed in Visual Basic.

Pneumatic control

The pneumatic cylinders are controlled by electronically operated valves. The valves are controlled via a relay board. Air is supplied by a compressor producing air pressure of 4.5bar.The air for the cylinders and valves has to be specially treated. Therefore an air filter was placed directly after the compressor and an air oiler directly before the cylinders. For each cylinder the extension speed can be controlled separately. To be able to do so, adjustable throttles were screwed onto each cylinder opening. In order to reduce the noise of the escaping air, sound absorbers were installed. After each start of the system an automatic check is carried out, in the course of which the cylinders are extended and run in to test the switches.

All components which get in contact with the remedy are new and disposed of after use. These are the stoppers, the suction tubes and the vials. The initial potency for this machine is a C200, made by hand from a C3-trituration using the multi-vial method. The remedies are exclusively prepared for use after prescription by a homoeopath and are specified as follows:

 

Sulphur 10MK Rem

A centesimal step takes 24 seconds, that is 1M in 6.66h, 10M in not quite 3 days and one MM in 10 months.

 

Commentary

All in all, the realization of this HTBLA-project as described above turned out to be difficult, particularly as strong mechanical forces are at work when operating the machine. After the first successful test runs and after improving the handling of the PC-control by revising the software, all screwed connections began to loosen due to the tremendous momentum of the strokes. Finally the machine was in danger of falling apart. However, after revising the apparatus once more, it could finally go into operation.

At the moment, the only machine of this kind is being tested in the Tuxer Alps near Navis/Tyrol at an altitude of 1660m. The water comes directly from a spring (set in prehistoric rock) which is poor in mineral substances.

After use the water flows through a piping system to a turbine which supplies the power necessary for the operation of the machine.

Conclusion

Potentizing machines have always been used for the manufacture of remedies which could not be prepared by hand because of their high dilution; they are no subsidiary system of potentizing by hand.

It has to be pointed out that the commonly used specifications of high potencies such as “10MK” are not based upon standardized methods. Manufacturers have always realized their purely personal ideals of potentizing machines, which has led to extremely different results. The fact that the mechanized manufacture of high potencies is not standardized in the European Homoeopathic Pharmacopoea furthers this case even more.

It is also of interest that since the existence of high potencies, more attention has been paid to constructive details than to the quality of the initial potencies. None of the historical potentizations by machine used H.’s C3-triturations, they always used the mother tincture.
