Hi, Absolutely Galled. I, too, wanted to purchase Gold Coin Grass locally, but couldn't find it. Instead I got a Milk Thistle formula that also includes Dandelion and Turmeric. I've had no more attacks since my first flush (I've done 4 now) and I started taking the herbs the same week. While I've passed many of the green pigment stones, I have yet to get anything resembling a calcified stone out, so I plan on getting the GCG tinture soon. I find it available online at 4 sites, although one is for practioners only. I haven't tried looking for the herb under it's botanical name, Herba Lysimachiae, but from my research I think the tinture is better for asorbtion anyway.
