When homeopathy is used for acute ailments like beestings, household accidents, bumps/scrapes/contusions, even some of the curious among us wonder. Some of the more practical of us care only IF it works, not how. The reason I believe it is useful to understand at least some of the principles is to understand how to use it most effectively; to gain the most benefit. And in those cases of chronic or more serious ailments, understanding is critical, and much more complicated. That is when a lay user who wants to be safe and effective needs to consult a professional.
