The Materia Medica is a book that lists all of the homeopathic single remedies and their symptoms.
Most common used remedies are listed in the homeopathic Materia Medica. The Materia Medica lists the single remedy and its corresponding symptom picture.
Because homeopathic medicines work on all systems of the body, mental, physical and emotinal guiding symptoms are listed in the following order of importance:
- Emotional
- Mental
- Physical
Each physical system is detailed from most important to least important:
- Mind & Head
- Each individual part of the body from head to toe (eyes, ears, throat, stomach, etc.)
- Each system from inside out (respiratory, circulatory , extremities, skin)
- Modalities (conditions that make the symptoms better or worse)
These symptoms listed in the Materia Medica are called guiding systems because the guide you to the right remedy.
It is important to remember that you don’t have to exhibit ALL of the symptoms for the remedy to be the correct one. The remedy that matches the majority of the symptoms is probably the one you need.
