I have done over 50 Liver Flushes in three years and have never used Black-Walnut tincture, HCL, or Ornithane. All you need for the basic flush is Epsom salt, extra virgin olive oil and grapefruit or lemons for fresh squeezed juice. I have added apple juice to my routine, I drink at least a quart for three to five days before flushing to soften stones and also use it to mix the Epsom Salts in. Occasionally I use Melatonin to get to sleep faster, but that is something I keep on hand anyway.
A basic Liver Flush is very simple, you don't need to add a lot of stuff to make it work.
