My allergies were such that during my allergy season, I couldn’t breathe through my nose without taking pills or nasal spray every day.
About 12 flushes fixed that problem.
I had two different types of large “stones” that came out.
One type of “stone”, when cut in half, had a dark green smooth-looking center with a concentric circle pattern.
The largest “stone” I found of this type was about 3/4 x 1/2 x 3/8 inch and it was one single "stone" as opposed to a "composite".
The other type of large “stones” were “composites”.
These "composites" may have been many tiny “stones” all clumped together. These did not have dark green, smooth looking centers with concentric circles.
The "composites" far out-numbered the "concentric circles"
The two types look exactly the same on the outside, you have to cut them in half to tell the difference.
I also flushed out a lot of “sand”, “sludge” and liver fluke skins.
I haven’t had to take an allergy pill since 2005.
The other major difference I noticed since I started flushing is I don’t get hungover anymore after drinking 6 beers.
I’m now shooting for an 8-beer hangover limit.
I suspect the large concentric circle "stone" was a real gallstone, based on my research. I suspect the large "composites" were congealed/clumped together sand and sludge from my liver/gall bladder mixed with olive oil. I doubt large stones can exist in the liver, but tiny ones can, and I think they tend to clump together with the olive oil. The large concentric circle stones, I think, come from the gall bladder.
Just my opinion, I'm not a doctor, your mileage may vary.
