Sm. Light green stone only epsom salt mixing w/OO?

Hi to all you experienced liver flusher,
I have a question, I read someone mentioned that small light green stone are only epsom salt mixing with OO, Is this correct? I heard that these stone were liver/gallbladder stone and I have passed these stones, posted my results and told that I had a good flush. Now I could be wrong,but I was under the inpression that the light green stones were liver/gallbladder stones and they come in many colors, sizes and shapes. If this is true, then I have had 3 very unsuccessful flushes and what I fished out the coliander and saved in my freezer in epsom salts and OO. I heard that OO can not coangulate?
PLEASE clear this one up for me because I am very confused now.
Thanks everyone and
"Happy Holidays"
