lady's mantle - alchemilla vulgaris

I've just started drinking some alchemilla tea for menstrual issues.

I found this article, http://www.herbalmedicinefromyourgarden.com/ladys-mantle-health-benefits/, which says that alchemilla vulgaris is also known as alchemilla xanthochlora and is the one to use for medicinal properties. (Though, I must say that I don't agree with the idea of douching - ever.) This article also claims that a. mollis is not effective as a medicinal.

So I tried to find out if my plant is a. vulgaris or a. mollis. I can't tell. I thought this analysis, http://www.chicagobotanic.org/downloads/planteval_notes/no24_alchemilla.pdf, from the Chicago Botanic Garden would help, but it didn't. I guess the a. vulgaris is a bit more spreading and open.

Here are the leaves of mine. When it blooms, I'll try to get a shot of that as well since I currently don't have a picture of that.

Any tips on use or how to tell the difference?

There are many varieties of Alchemilla.

Here are Wikipedia images of A. vulgaris and A. mollis.

Thanks John. I think the a. vulgaris pic is a bit pre-bloom and the a. mollis pic is during bloom, so I'm still not getting the difference.

Is it just me?
