Dr Colin B. Lessell 
A Companion To Homoeopathic Studies 

Some are content with driving fast cars; others want to know how they work. In this intriguing book for students, practitioners and pharmacists of all levels, readers will find nearly everything they need to know about the nuts, bolts and cogs of homeopathy.
Adhering to a philosophy that pure empirical facts are meaningless without sound theory to bind them, Dr Colin Lessell reveals the physiochemical nature of remedies, the way they exert their effect on the living organism, the mechanics and history of their production, and the principles by which their selection and dosages are determined.
Many of the topics in this book are only barely touched on in the most formal courses, making it a true companion for anyone who wishes to have a more profound knowledge of homeopathy, or who just wants to make sense of the infinitesimal.
