This is indeed the most informative book on homeopathic medications that I have ever seen. While using the repertory can be trying, once you find what you're looking for, and take the medication, you'll probably be glad you took the time to delve into the matter so deeply.
My family and I use homeopathic medications all the time, both single and combination remedies. For us, they've helped with everything from allergies tonsillitis to pain after surgery. Best of all, they're fairly inexpensive, and don't have the side effects that "real" medications have. I attribute much of my health to the Materia Medica, and continue to use it when a health issue comes up.
