Try the web site: NaturalHealthSupply.com HCI is listed as Betaine Hydro-chloride. This web site has all ingredients for Hulda Clark
's recipes for internal cleansing.
Check her book again because the HCI is listed as an ingredient in the kidney cleanse
protocol. It is not part of the Liver Cleanse.
I have not purchased from NaturalHealthSupply.com before, so check them out before you buy.
You can find her current recipes on curezone.com web site. Here!
