Not all tinctures are the same in quality, so be sure to only buy from highly honored companies. When herbs and tinctures don't work, it is usually due to using a cheaper brand.

Angelica for use to control bleeding before the placenta.
Shepherd's Purse for use to control bleeding after the placenta.
