This is a good read, and an option for people who can't "stomach" doing gall stone flushes or a definite read for anyone needing to detox. Karen Hurd is a nutritionist who has seen how the body responds and heals by adjusting the foods you eat (especially adding in soluble fiber). She strongly recommends eating a minimum of 1/2 cup of legumes a minimum of 6 times a day. Note: in her book and elsewhere on her website, just not on the gall bladder page, she does say you can take psyllium if you can't get yourself to eat beans and other legumes.
It takes time, Hurd says, about 6-8 weeks, but over that time soluble fiber should clean toxins by getting rid of old bile and actually dissolving gall stones. If you read her book or other health topics on her website, addressing the liver through using more soluble fiber should help with all sorts of digestive issues too, like Crohn's Disease, IBS, etc., and also is part of how to address adrenal fatigue, fibromyalgia, and chronic fatigue syndrome. This link is just to her gall bladder posting, but definitely browse her other topics.
