I've been flushing for the last 16 months or so with good results, but i neglected to use any sort of stone softener, and now i have a big stuck stone and it's making me really sick. Basically the last 5 or 6 flushes have been fruitless. Please, if you have used one or more supplements like GCG (gold coin grass) or malic acid or chanca piedra, can you share any pertinent facts from your experience? Namely, which one do you think is faster or more effective? i am currently using a chanca piedra tincture and drinking apple juice and also taking a malic acid supplement. I am thinking of purchasing some of the GCG tincture from julia chang. i think i don't have a lot of time to screw around because i'm losing weight and i got really skinny so i want to be sure i'm using the best medicine ASAP. thanks!
