have you found the gold coin grass locally. I know its 17 month late but recently my daughter was found to have gallstone (1CM) and she did the flush. Bits and pieces of debris and sludges were purged. Whats left now its that 1 cm stone that needed to crush. While waiting for the GCG tinctures to arrive, I have my daughter prep herself with GCG found locally. Since it is not tincture (alcohol based) she brewed the herb as tea. At least it stop the pressure. Any local chinese medicine shop should carry this herb. Tell them you wanted "kum cheen choe" in Cantonese.
They will understand. One pound costs me US$8.00. ^You only need about 5 oz to brew a pretty strong tea. liz
