Les symptômes mentaux en homéopathie is a reference work authored by R. Dr. Dufilho and published in 1998 by Librairie Marrimpouey. Spanning 342 pages in hardcover format, the book focuses on the mental and emotional symptoms that homeopathic practitioners consider when selecting remedies. It presents a systematic overview of psychological indicators, linking them to specific homeopathic medicines and their characteristic profiles. The text aims to serve as a practical guide for clinicians and students interested in the psychological dimension of homeopathic case taking. By organizing symptomatology according to homeopathic principles, the volume supports the individualized approach central to the discipline. While the work assumes familiarity with basic homeopathic theory, it provides detailed descriptions that can aid in remedy differentiation and case analysis. The publication reflects the late‑twentieth‑century interest in expanding homeopathic materia medica to include mental and emotional aspects.
