Considering that you're nursing....

...and that for your own health Liver Cleansing sounds like a high priority, you'll probubly want to use methods that won't adversely affect you're milk supply.
First of all, post you're question under the ask Agnes, ask Lillian forums directly to them. Some of the Chinese herbs may be helpful, some may not be for when nursing. Safer may be to drink lots of fresh, homemade apple juice as much as possible before next Liver Cleanse (liquify in a blender if you don't have a juicer).
Ortho-phosphoric acid (I don't know a lot about this, but hopefully others here have some advice on it) which is also in Coke. Some people do a Coke Liver Flush which of course is not in the best of health, but considering your condition, may contain the ortho-phosphoric acid needed to dissolve stones?
As for parasite cleansing, I would urge you to get a "Zapper". It's very important to kill the parasites living in your Liver since substances they produce can keep it from releasing stones. Then your Liver Cleanse will be more effective. While I was nursing, I used the Zapper many times, it didn't affect my baby or milk supply at all. What it did do is kill off clogged duct infections and general strep infections that I had 8 times while nursing. I also did the Herbal parasite Cleanse, the Wormwood did lesson my milk supply a lot, but I was able to regain it after. (It is recommended to "Zap" every day for a week and then Liver Cleanse.) The "Zapper" can rid your body of other infections as well that your radiographer is concerning you with.
Please keep asking questions on here, also post on the other sites mentioned! I wish you and you're baby the best!
