That's what I read also at Andrea's forum-- if you are cleaned out in the colon and lower bowels, and are in the condition where you are having 2-3 bowel movements a day, that could be enough to rid parasites in that area!
I still love doing the parasite cleanses though- cuz i've had luck with them.
Still i would do a Liver Flush at the very end of all the other flushes. Glad to hear people could use other oils besides olive oil-- cool! :-)
Some herbs have cleansing properties-- such as Cascara Sagrada for the colon or Milk Thistle to detox the liver. Senna is an herb with a laxative effect. Oil of Oregano is the oil from the oregano plant and it has strong anti-biotic properties. Thyme also is a good herb used for anti-biotic purposes. It's really interesting reading up on all the herbs uses that we take for granted!
