According to homeopathic philosophy, each and every patient needs to be treated as an individual. As individualization can be done on basis of PQRS symptoms or red line symptoms, it is a must to know them.
Also, to reproduce the entire materia medica at time of clinical practice is practically impossible but the redline symptoms of common drugs if remembered can be life saving.
This small book 'Seven-Hundred Red Line Symptoms', details PQRS symptoms of commonly used medicines. The symptoms have been derived from most authentic source, 'Cowperthwaite Materia Medica'. This book will be helpful to busy physician as well as to those who completely repertorize the case and revert to materia medica to find the best simillimum.
