Crossing the Line between Natural and Just Plain Nasty?

I am a firm believer in the fact that the most natural and readily available products we need to sustain us were already given to us by God in nature.  However, after coming across a cookbook that contains semen-based recipes I started to think that there may be a fine line between natural and just plain nasty!  I mean...to each his own but, I really do not see how semen can provide any health benefits to someone. 

In case you are curious, the book it called, "Natural Harvest- A Collection of Semen-based Recipes".  It claims that semen is not only nutritious but, also provides a great texture to any dishes it is in. 

I'm sorry but, this just takes the phrase,"home-grown" to another level; a level that I will not be entering at all.  It makes my stomach to churn just thinking about it!


Would you try a semen-based recipe?  What is another "natural" product, remedy or technique that crosses the line for you?
