Well-researched approach from a busy and experienced Swiss homeopath. Polarity analysis is based on Boenninghausen's Therapeutic Pocket-book in which polarisation of symptoms (eg: better or worse from heat or motion) offers clear differentiation between remedies from a very manageable pool of 133.
The method is easy to learn and apply, with 40 illustrative cases. The incorporation of checklists and questionnaires enhances learning.
This will help you become a speedier and more accurate prescriber.
