It looks like you feel what is right to do, but just confused a little.
I just found my garlic/pumpkin seeds/UT parasite control program was not working and started another cleanse.
One has to learn hard way!?
I guess herbal supplements are OK to take between flushes and many people were taking some parasite killing herbs during flushes.
I think it is good idea to start from colon cleansing in between of flushes, changing over to kidney cleanse after parasite control cycle is completed.
If not - parasite will cause stones to grow faster then you flush them!
