Unfortunately, I can't answer your question about
curcumin, but as for gallbladder stones, I did, before I knew I had lyme, the crazy dr Hulda Clarck's liver and gallbladder cleanse, and as dreadful as it is, I can say it works. I expelled a lot of gallbladder stones.
I did it not knowing what was wrong with me, so I tried everything. I'm not sure if it is advisable to do that having lyme, or to do it at all, it's worth googling, I think that the stones must not be above the certain size to be able to perform the cleanse, but having an aim of getting rid of the stones instead of worrying about
curcumin could get you through the "unpleasantries" of drinking a glass of olive oil with pressed grapefruit, feeling nauseous, not drinking water for a while, having repetitive glasses of bitter epsom salt... It a lot of fun.
