Hopefully one of the 4 people above will chime in. They are the experts who know the most about The Master Cleanse and how they fit in with other cleanses.
The reason why you want to do a Liver Flush after the Master-Cleanse is because the Master-Cleanse can be stone-forming. In the Hulda Clark FAQ, it does say that a parasite cleanse should be done before the liver flush. The order I chose to take was recommended to me by the oldtimers here in the forum. Honestly, it may be different for others depending on thier needs.
Well, let's wait and get more opinions from the experts.
