Yup, if no one answered yet. Just jumping in here, so I don't know what was said up the thread. Turmeric, golden seal, and ginger are all in the same family, and have some similar properties. Turmeric is amazing stuff. Good to put on cuts, wounds, infections, pimpls, boils, and to take internally for all manner of illnesses. It's good to eat every day in food.
As far as I know, just two different spellings of the same thing. Curcumin is the active ingredient, iirc.
