Potency selection is an issue that has remained ambiguous for nearly every homeopath. We are all taught about the three scales – Decimal, Centecimal and 50 Millecimal and get to know the frequently used potencies from each scale. But how many of us have pondered deeply enough on the common potencies that we use – The 6, 30, 200, 1M, 10M series of Kent or the French series of 3C, 6C, 9C, 12C, 15C and so on? What justifies these potencies and these large jumps from one potency to another? Nearly every homeopath has thought about these issues at some point of time but how many of us have found any answers?
For a change, Joe Rozencwaig, the author of ‘The Potency’ has succeeded to find some answers. He has been able to relate the progression of homeopathic potencies with the Fibonacci series. So the obvious question is – What is the Fibonacci series?
In mathematics, the Fibonacci numbers are the numbers in the following sequence:
By definition, the first two Fibonacci numbers are 0 and 1, and each remaining number is the sum of the previous two. Some sources omit the initial 0, instead beginning the sequence with two 1s.
In mathematical terms, the sequence Fn of Fibonacci numbers is defined by the recurrence relation
with seed values
The first 21 Fibonacci numbers (sequence A000045 in OEIS), also denoted as Fn, for n = 0, 1, 2, … ,20 are:
F0 F1 F2 F3 F4 F5 F6 F7 F8 F9 F10 F11 F12 F13 F14 F15 F16 F17 F18 F19 F20 0 1 1 2 3 5 8 13 21 34 55 89 144 233 377 610 987 1597 2584 4181 6765
The Fibonacci series seems to be omnipresent. It can be seen in nature in the mathematical proportion of shapes of flowers, cacti, vegetables like Brassica, Pineapple, Nautilus Shell, Butterfly, inner and external human ears etc. It is also used in many mathematical, accounting and trading formulas. It is even present in art and music. This rhythm found in nature led Joe to using the same rhythm in homeopathic potencies and the series of centecimal potencies thus used were called the Fibonacci Potencies.
Joe has used these potency series for many years and in this book he has outlined his journey to this discovery and the experiences he has gained so far. This book is unique because it provides mathematical answers to many questions related to our remedies and potencies.
There is only one thing that I feel needs to be modified in this work. The examples relating to the presence of Fibonacci series and the Golden Ratio have been given before these terms are explained in detail. So while you go through the examples, you do not understand what these examples mean. The detailed explanation only comes later. Apart from this, the book is pretty thorough and with decent print quality.
How useful this series is in wider practice, only time will tell but if you are interested in reading some new thoughts about homeopathic potencies and want to know how to use Fibonacci potencies in your practice, then this book is for you.
