I was talking about real herbs that exist, like wild yams or things that naturally mimic or have progesterone in them.(My inner chem nerd is coming out) and then the fact that she refuses to get married so she has no chance anyways 

I apologize, I am going by a false name. I mean Elizabeth of York, the Queen to King Henry the 7th and married into the Tudor house, unifying the York and the Lancaster households and ending the War of the Roses. I always called her Elizabeth of Tudor because she was the original Elizabeth of Tudor. That's a regional thing, sorry. 

And Elizabeth the 1st wasn't a bastard...Anne was Queen Consort and she was married to Henry the 8th when Elizabeth was born so under the Church's eyes she was a legitimate heir. Which didn't even matter in the end because Queen Mary of Scotland got the throne anyways haha
