Yes, I think there have to be various ways to cleanse the liver of stones.. and I also believe we have to listen to our bodies.. so if it's making you puke and you've found an alternative.. all well and good. I too think I may have found a gentle way by externally applying castor oil and getting in the Far Infrared Sauna for half an hour.. need more experimentation yet. But the flush came about after looking at the way various cultures took a tablespoon of olive oil daily for gallstones... again a far gentler way than the large quantities called for in the flush. Yes, of course drastic measures are called for sometimes.
By the way, I wasn't suggesting the green stones come from the oo... they are obviously cholesterol... simply coming from stimulating the liver by whatever means.
