Lecithin dissolves stones. Lecithin is in the olive oil for the flush.
Why not just take lecithin, or a tablespoon or two or olive oil, every day and avoid going through the onerous flushing routine?
It seems to me constantly chipping away at something will do more good in the long run than massive attacks done infrequently. Or in the case of people who seem to do these flushes on a routine basis, I imagine the whole Liver Flush routine with the Epsom Salts is probably fatiguing to the body.
