Goldenseal has a long history of use for bleeding, especially gastric bleeding. I suspect it is due to the Hydrastine content, which is a superb mucus membrane tonic. Lloyd Brothers at one time made a colorless Hydrastis extract which was a Hydrastine extract, that was indicated for gastric bleeding, menorrhagia, mild post-partum bleeding, intestinal bleeding, etc. And there is plenty of organically grown Hydrastisin the market place so you can use it and not worry about using an endangered species
