Hey!
It is very common where I live, in Spain , to take strawberry and raspberry leaf tea for pregnancy and I wonder if they change hormones or do something different?
I actually do remember seeing something in some of my recent research about strawberry having some sort of hormonal effect, though I can't remember what it was, having dismissed it as not applicable to my own needs. Sorry. You could hop on scholar.google.com and try to ferret something out yourself. There's also a website called "Examine" that lists known, but generally older, research about the effects of medicines, both pharmaceutical and traditional.
For the cutting edge, you want Google Scholar.
You WILL need to either pass a paywall for some stuff on Scholar, or keep sifting through until you get articles with free access, which are few.
