Anyone written a book (or know about it) advice for legality

Hi! I have a great idea for a book that would be based on public knowledge including menstrual cycles and the symptoms for each stage, etc. it's going to be tied in to other stages of life and whatnot, and some humor.

Since this will be based on more science and I'll be pulling info from sources, what's the legality for publishing?

I know of course everything needs the proper acknowledgement and whatnot..but I'm just looking for a little more info and figured I'd post here as well as do my own research!

Thanks in advance!
