It is a guide for you, i.e. for a woman of 21st century. It takes care of every minute detail required to be known by a teenager girl or by any adult woman which she, otherwise, will not know as they always hesitate to ask! Instead of acquiring a second hand information from the elders or from friends and use their hearsay treatments, know yourself the root cause of the trouble and get yourself treated scientifically.
A book every woman should possess.
