There is not just one match for a sore throat. Wow, would our lives be more simple if every remedy was only for one health complaint. Or that everyone with the same constitutional type were the same in behavior and health problems. In reality, each book, or Health Professional, or online description, captures the flavor and emphasis that the author wishes to impart. The author has personal experiences and successes that offer additional information.
Authors use different resource material.
Materia medicas themselves differ. Information from Provings may be condensed or written in modern terminology. Emphasis may be according to the theme of the book or article. It is not easy to look past our own description of our illness, to seeing keynotes or underlying themes in remedies. Some people may dismiss taking a remedy given by their Health Professional only because one book description doesn t list their illness.
