'Margriet Plouvier has created an extremely workable overview of the functioning of different potencies by systematically and logically arranging her observations of the therapeutic effect after prescriptions. This is a great support when choosing the appropriate potency for a case.
There are many theories about the use of the best potency, but until now it is more tradition and conviction that are determinative instead of systematic research. Being the pharmacist of a homeopathic pharmacy, I see many recipes every day, so U have an overview of many prescriptions. I also have knowledge of clinical and fundamental research in homeopathy: this research doesn't show any useful difference of result between D, (X), C, K or LM potencies.....this book shows the corresponding effect of potencies from different potency-systems.'
