Dr. Allen left an indestructible work on homeopathic materia medica, one that is true to Homeopathy and immensely helpful to every physician who consults it.

Keynote symptoms of a drug convey its crux to the physician. This book will assist students in grasping the core of the drugs and applying Materia Medica clinically and with efficiency. Additionally, the inclusion of a repertorial index makes this book an essential mate for both students at undergraduate, postgraduate, and competitive levels and practitioners alike.

This Homeopathy book is based on Hering's Guiding Symptoms. For each drug, Allen selected some symptoms from "Guiding Symptoms'' according to his sense of priority and his own personal experience. The remedy relationships in Allen's "Keynotes' ' are also based entirely on Hering's Guiding symptoms.

Key features:-

Keynotes that convey the central theme of a drug.

Entirely based on writings of a great master in Homoeopathy, Dr. Constantine Hering‘s Guiding Symptoms
