It was often said that "Homoeopathy treats the patient and not the disease" but the relevance of the statement was only limited to olden days when disease diagnosis was not much developed. The statement only highlighted the fact that a homoeopathic practitioner could treat/provide relief to a patient based on the available symptomatology barring the nosological labelling which wasn't that well developed. Knowledge about diagnosis in earlier times was limited and was primarily done for prognosis of the case. With advances in sophisticated techniques, medical diagnosis has come a long way, from empirical diagnosis to clinical and laboratory diagnosis which has widened its scope in management of the patient. This advancement in medical field has been of paramount importance for a homoeopathic practitioner as well who is faced with the challenge of treating various diseases. A homoeopathic physician has a dual task of establishing a disease diagnosis as well as a patient diagnosis as per the individualistic holistic approach of the system of medicine. Both are vital in identification of the indicated remedy for the management/treatment of the patient. Casual observation, as well as more systematic study of prescribing practices, frequently reveals a pattern of tremendous diversity among prescribers in the treatment of even the most common conditions. A Standard Treatment Guideline (STG) which provides standardized guidance of diagnosis and therapeutic management of a diseased condition can be a solution to this therapeutic anarchy. Also, a simplification of treatment can facilitate the objective AI appraisal of value of homoeopathic system of medicine. Over the years, RCTs/Observational studies, experiences of homeopathic practitioners have tried to identify remedies suitable for various disease conditions per se. The Council with the aim of conducting research on scientific lines in Homoeopathy has completed 119 clinical studies and has collected data of most useful medicines in various diseases. Council has made an attempt to develop a standardised guideline for management of diseases, based on expert consensus, review of current published scientific evidence of accegtable approaches to diagnosis, management and/or prevention of specific diseases; data from research studies. Such a systematically developed statement can assist practitioners in rational decision making about appropriate health care for specific clinical circumstances, help maintain quality standards and also represent one approach in promoting therapeutic effective and economically efficient prescribing. In the beginning of this initiative, eighteen diseases have been identified. Each condition gives clear presentation of definition, symptoms, epidemiology, diagnosis, differential diagnosis and its general management. Apart from this the STGs also include information about various outcome measurable questionnaires which can be used by the homoeopathic practitioner for disease assessment, treatment evaluation (follow up) and research. An algorithm of the treatment process given at the end of each disease condition helps in having bird's eye view of disease and also indicate appropriate time of referral. The book puts forward a group of medicines found most commonly indicated in each disease as identified from published research papers, Materia Medica and inputs of experienced homoeopathic practitioners. These STGs are prepared for wider dissemination and implementation by the practitioners at large. The Council welcomes inputs and experiences of practitioners for betterment of these guidelines and looks forward to continuous updating. While it is hoped that the book may prove to be a concise and ready reference, it makes no pretension to being anything more than an introduction to the important conditions; in no sense is it put forward as a complete treatise. Readers are advised to check the most current information. It is the responsibility of the practitioner, relying on his/her own experience and knowledge of the patient, to make diagnosis, to determine dosages and the best treatment for each individual patient, and to take all appropriate safety precautions.
