Synopsis There are many books written on skin ailments in homeopathy but to my knowledge, there is no exclusive book on nails and their diseases. It is because the subject is very much limited, short and medical narrations cannot be made voluminous even if someone desires to give this subject a longer and exclusive length. So, this book has its beautiful brevity. My objective of writing this book is to make the subject interesting and to the point with logical sequences so that students and practitioners select the required choice without wasting time in confusing notes found in other books. Selecting therapeutic and repertory of nails is section-wise and hence easier than finding the same from Kent or other voluminous repertories. Treatment of diseases of nails is not different from other diseases. The principle of homeopathy applies in all the diseases, the symptoms being the sole criteria. The advantage from homeopath's point of view is that he or she can examine the progress of cure with naked eyes than relying on the version of the patient. What counts here in case of nails is that one should have proper knowledge of all those factors like symptoms, etiology, pathology, diagnosis, treatment and prognosis. It is the clinical and practical experience that makes us aware of diseases of nails. Clinical experience must be supplemented by knowledge of some concisely explained textbook.
