That flush was brutal and the results were not any better than a regular Hulda Clark flush. I don't recommend it unless its a last ditch effort where nothing else has worked. It is definitely not a flush for beginners.
I don't do that particular flush, but I do Dr. Lewis's flush which also uses 1 pint of olive oil and I love it! I started flushes using Dr. Clarke's method, but eventually I stopped getting stones out, so I started doing that one and found for me, it workd much better and I get out alot more stones, but I wouldn't recommend starting out with that one.
