Theory of the Dynamization of Medicine


It is impossible so to separate the dynamization theory from the doctrines respecting the doses as to be able to treat of the one without reference to the other….


The dynamization theory not essential to homoeopathy-Hahnemann first hint of it-Solution increases the power of the drug by bringing it to bear on more points of the living fibre-Difference between the action of a hard, dry pill and a solution of the same medicine-Medicine act dynamically not atomically-Hahnemann asserts the greater power of the smaller portion of medicine in solution-Curious piece of dynamical arithmetic-An imitation of Brown’s scale of excitability-Futility of all such calculations- Further development of the dynamization theory- Wonderful effects of succession and trituration-The homoeopathic attenuations are said not to weaken but to exalt the medicinal power-The power of the attenuation proportioned to the number of succussions they have received-His fear of over-succussing-No need for dilution- He loses his fear for hyper dynamizing-Wonderful effects of dynamizing-Frequent alteration of Hahnemann’s views-His disciples better the instruction of the master-Korsakoff’s infected globules- Hahnemann’s reply to Korsakoff-Gross gives his adhesions to Korsakoff- And goes beyond him-Plaubel is favourable to infection-Jenichen’s high potencies-Disclosure of his undivulged secret-Plumbum the beginning and the end of Jenichen’s celebrity-Gross becomes Jenichen’s trumpeter-Boenninghausen kills two dogs without a stone-Hering’s Hahnemannism-His aerial potencies-Tietze ascribes dynamization to electricity- Investigations with the microscope-Segin’s investigations- Mayrhofer’s observations- Microscopic appearance of attenuations of gold, silver, mercury, iron, lead copper, tin, zinc, arsenic- mayrhofer’s deductions-Koch’s examination of mercury-Rummel’s illusions with the 200th dilution.


IN former lectures I have already warned you that we should find that Hahnemann had aggregated round the homoeopathic principle a number of theories and doctrines which had been disputed by many of his disciples, and which might all be proved to be utterly valueless., without detracting in the slightest degree from the truth and excellence of the homoeopathic principle.

The subject of to-night’s lecture belong to those theories and doctrines which Hahnemann subsequently engrafted on his therapeutic law, but which are by no means necessary to that law, and accordingly we may, without incurring the change of high treason to homoeopathy, or without forfeiting our claims to be considered homoeopathists, freely subject it to the searching light of criticism, and accept it if we find it accords with reason and truth, or reject it under opposite circumstances.

As I have done with others of Hahnemann’s theories and peculiar views, I shall endeavour to trace historically the development of the theory of dynamization, as I find it from a close and careful study of Hahnemann’s writings from the earliest period to the latest.

It is impossible so to separate the dynamization theory from the doctrines respecting the doses as to be able to treat of the one without reference to the other; indeed, we shall find that the doses Hahnemann latterly advised owed their excessive exiguity, or this theory was devised to explain the effects of small doses.

In his first essay announcing the discovery of a new therapeutic principle, published in 1796, no allusion is made to any doses different from those in ordinary use, nor is there any mention made of any peculiarity in the mode of preparing the medicines; consequently nothing is said about dynamization. In an essay published the following year we still observe no peculiarity on these points, and in his writing up to 1801 nothing is to be found to lead us to suppose that there was anything exceptional in his made of employing drugs, save that he used them in accordance with the law he had enunciated in 1796, and advised that every medicine should only be given singly and alone.

It is in his little work on Scarlet Fever, published in 1801, that we have the first forebodings of an unusual mode of preparing the medicines, of the infinitesimal doses and of the dynamization-theory. The dose of opium there recommended for the treatment of a certain form of the scarlet fever is very small compared with the ordinary dose, and the tincture of opium is to be prepared by intimate mixture of the opium with the alcohol, by well shaking the bottle in which the solution is performed. He lays particular stress on the intimate mixture as well of the opium with the alcohol as of the tincture thus prepared with the vehicle-water or beer-in which it was to be administered. The object of the dilution in this case seems, however, to be solely to diminish the size and power of the dose; and there is no question as yet of any increase of power by the intimate mixture by means of the succussion employed.

In the preparation of the prophylactic tincture of belladonna, mentioned in the same essay, he directs that the several dilutions used-they are three in number, and prepared in the proportion of one of the drug to 400, 300, and 200 of the vehicle (diluted alcohol) and should be prepared by diligent shaking for a minute at a time. The object of this dilution was to diminish the power of the medicine chiefly, for he remarks that in patients of very tranquil disposition the dose he orders, as a general rule, is not sufficient; it must be increased and stirred for a minute longer with the fluid vehicle. Immediately after this, however, follows what we may consider the germ of the future dynamization theory. “It is scarcely credible,” he observes, ” how much this and every other medicine loses in power, if we allow it to be licked up simply and unmixed with anything in a spoon, or give it only on sugar, or though we drop it into a fluid administer it without stirring it well up with the vehicle. It is only by stirring, by brisk, long – continued stirring, that a liquid medicine obtains the largest number of points of contact for the living fibre, thereby alone does it become right powerful.” Thus the increase of power supposed to be gained by the medicine from its intimate mixture with the non-medicinal fluid is thought to be owing to the greater number of points of contact it then presents to the part to which it is applied.

This doctrine, by which the mere stirring or shaking with a non- medicinal vehicle was alleged to increase the power of the drug, naturally met with opposition from those physicians who believed that an increase of the material quantity of the drug was the sole way of increasing its activity. Accordingly we find Hufeland asking, with a sneer, ” What effect can the hundred-thousandth part of a grain of belladonna have?: To this questions Hahnemann promptly replies, in the journal of his querist, by a short article, which you will find in the Lesser Writings, entitled “On the power of small doses of medicine in general, and of belladonna in particular.” He refers to the difference observed in the effect of a hard dry pill of extract of belladonna and of a single grain of the same extract dissolved in a couple of pints of water, by being well rubbed up with it, and then strongly shaken for five minutes, and taken by the most robust labourer by teaspoonfuls within six or eight hours. He further adds, that a single drop of such a solution, mixed with six ounces of water, by being vigorously shaken, will possess enormous power; for if a few teaspoonfuls of it be given to a patient whose disease was one for which belladonna was suitable, they will bring him to the brink of the grave.

In explanation of the much greater effect of the solution thus prepared than the dry undissolved extract, he says that the latter presents few points of contact to the body, whereas the thorough solution comes in contact with many more points of the living fibre; and, he adds as the medicine does not act atomically but only dynamically, it excites much more severe symptoms than the compact pill, containing a million times more medicine, is capable of doing.

He then refers to the exalted excitability of the vital force in diseases, and illustrates this by several familiar examples, and he cites some instances of paralytic and nervous diseases, which he had cured with a hundred thousandth, and even a millionth part of a grain of belladonna.

At this period, then, we have the embryo of the dynamization – theory, though still very different from what it afterwards grew to under Hahnemann’s fostering care. He contents for an increase in the power of the drug action from its thorough admixture with a non medicinal vehicle, and he accounts for this increase of power by the greater number of points of contact it presents to the living fibre, in consequence of its minuter subdivisions. Another element also included in the doctrine, as it stands at this period, is the exalted susceptibility of the diseased organism for the appropriate medicine; this he puts forward by way of explanation of the power of the minute dose he finds to be sufficient. The allegation that the medicine acts “not atomically but only dynamically,” is that which has most bearing on his future dynamization-theory.
