Clarkia is about worthless. It is not the original formula that Clark had in the beginning. Do either the Barefoot or the Humaworm. Humaworm for 30 days, if you want to do that one, or Barefoot formula each and every day. At least a TBSP in am and a TBSP in pm. Stay on A dewormer all the time. Humaworm for 30 days, then bareoot stuff for 90 days, then back to Humaworm and so on. Good luck.
EDIT: Why not go with Doc Sutter's Natural Healing Paradigm? I've done his protocol for a year. Got my life back, too. Most ALL parasites and liver stones are gone. http://www.docsutter.com
and "ask sutter" here on CZ.
