On the subject of the thread...I've recently discovered Shepherd's Purse for bleeding.
http://en.wikipedia.org/wiki/Capsella_bursa-pastoris
It's a common cruciferous "weed" that flourishes across North America in the summer. Effective as a tincture or poultice, and the entire plant is edible.
I was dealing with prolonged menstruation while travelling and picked up a bottle of tincture after doing some internet research. This stuff is IMMEDIATELY effective as a vasoconstrictor - as you drink it (I added 15 drops to raspberry-leaf tea) you can feel a "tightening" sensation. I stopped bleeding within an hour of drinking the tea, and after a few days of waning treatment returned to a normal cycle. Upon further research, I found that it was used in WWI as a battlefield medicine when conventional medicine became scarce. I'll be wild-crafting tincture this summer and keeping it around in case of emergencies.
Here's the botanical.com entry for more info on medicinal uses:
