Health teachning about cholelithiasis?
Answer: You mean like this?.
Opus have provided a link with solid information on gallstones, that I won't metaphorical on.
Your question is quite oblique. I assume you are asking in this category because you want to know if there are any special diets or treatments to dissolve gallstones.
There aren't. That's not to articulate that you won't find lots of things recommended by Naturopaths, but they don't work at all, cost a lot of money, and roughly make you feel miserable
Conventional prescription has tried a wide mixture of things to try and deal with gallstones medically,(ie non-surgically) and none of them work.
The standard of non-surgical safekeeping is to lose weight, control your cholesterol, avoid eating fatty/greasy meal.
