The Science of Homeopathy – page 158

The centesimal scale is the most commonly used in homeopathy. It is based upon serial dilutions of 1/100. Each centesimal potency, therefore, is equivalent in dilution to two decimal potencies. A 30c potency is the same as a 60x, considering only the amount of dilution. Finally, some homeopaths are using potencies based on serial dilutions of 1/50,000 at each level. These are called 50-millesimal potencies, but common parlance refers to them simply as millesimals. This unusual dilution factor was suggested by Hahnemann late in his life, based upon his preliminary experimentations with different degrees of dilution and succussion. For example, a lm potency is a dilution of 1/50,000, and a 3m potency represents a dilution of 1/125,000,000,000,000 (1/50,000 x 1/50,000 x 1/50,000).

It is very important to understand that both dilution and succussion are important in producing a given level of clinically effective potency. For each potency level, a standard number of succussions are performed, as well as dilution according to the particular scale being used. Figure 14 shows a table in which potencies of equivalent number on different scales are compared as to their dilutions and the number of succussions received (assuming a standard 100 succussions at each level).

Since both factors are involved in potentization, it is incorrect to equate potencies according to mere succussion or mere dilution. For example, if we compare a 30c and a 30x, both have the same number of succussions (3000), but they have different dilutions (1/1030 for the 30x and 1/1060 for the 30c); so, the 30c is a higher potency by some amount. Conversely, if we compare two remedies of equal dilution, a 30c to a 60x, we see that the 60x is of a higher potency because it has had 6000 successions, compared to the 3000 given to the 30c.

Occasionally, the problem arises in clinical practice as to which po- tency on one scale corresponds in effectiveness to a potency on anoth- er scale. For example, suppose a patient has had a certain effect from a 30c, the same remedy is still indicated, but the homeopath wants to change to a millesimal scale. Which potency corresponds on the mil- lesimal scale to the 30c? If a 9m is given, is it a higher potency because the dilution is greater? Or is it a lower potency because the succus- sions are much less? This question cannot be answered with precision as yet, but it should be a good subject for investigation in the future. Someday, it may be possible to devise a formula which would provide this comparison, but as yet there are too many unknown factors. For example, do succussion and dilution have equal importance, or is one more important than another? Or is one factor more important at lower potencies, and the other at higher potencies? Does a given number of
