I want to do a Liver Flush (I'm coming off a Master-Cleanse now) and I'm trying to understand all the bits and get it right: I was reading the Hulda page ... Why do you need HCl to sterilize the olive oil? Do you have to? Where do you get it? Do you have to use orintine and Black-Walnut tincture? Why do you need these? Why arent' these listed on the "what you need" part at the top. Any clarification would be appreciated.
