I finished an Master-Cleanse in August and did a Liver Flush after about 10 days on the Clarkia (quit taking the Clarkia the day I did the LF). I feel like I'm pretty cleaned out as I go 3X a day, but I'm taking Oxypowder now for my Bowel Cleanse and am re-starting the Clarkia after a break. I should be able to tell if your theory about retaining toxins is accurate. I really appreciate your answering my ?. Interestingly enough, my mother who is suffers from constipation has a sore in the same area on her head and hers is inflamed all the time. Where mine didn't flair up until I started the Clarkia. I'll report back in a few days to let you know if it flairs up again during the 2nd half of the parasite cleanse.
