Potency - one of the most vexed issues in homoeopathy - is here put under the microscope. An interestingly argued case is put forward for adopting, instead of Kent's method, the Fibonacci series of potencies. This is based on the Fibonacci sequence of numbers which occurs everywhere in nature - from the arrangement of pine-cone scales, to the structure of DNA. From his use of the series the author draws various conclusions, suggesting that Fibonacci potencies, correctly prescribed, may yield better, longer lasting results than the Kentian series. You are encouraged to try it out for yourself, and this book explains how.
