Is it black tea?
first off I cannot believe the pain people, and now me, go through with gallstones. FOr the love of all things holy...I literally screamed and the ONLY thing that gave me relief was sticking my fingers down my throat and getting whatever undigested food out! I had instant relief I mean from writhing in pain, asking for someone to kill me (burning shoulders, spear through the sternum and back pain) to instant relief. The production of bile, the stones, the agitation of the gallbladder they are all under massive pressure when you eat, especially high fat/fried foods. ( I ate a jerk chicken poutine (poutine is Canadian fries/cheese curds/gravy) and a butter tart) and I almost passed out. I threw that c**p up and felt instant relief, so if you feel nauseous at all, and you feel an immense amount of pressure and pain I recommend the fingers down the throat-get it out and you will feel better. Then like me clean up your eating act! Low fat, lots of fruit and veg, no ice cream high fat cheese, lots of water and nothing fried. I am hoping I can stay on a strict diet and never go through that pain again. Good Luck...heating pads, and someone rubbing your back really help as well.
