Dherbs.Com offers various healing/cleansing kits and programs. All of these special kits and programs last approximately 3-weeks (20 days to be exact). There is no specific time frame set for you to wait after performing one cleanse and before doing another. The choice is up to you. Many people use the Full Body Detox back to back and some folks perform it three times in a row (consecutively). You know your body and tolerance levels better than we do, so the choice is totally yours. You could do one cleanse and jump right to the next, or you could wait 3-7 days, one week, or 2 weeks and then proceed with your cleanse. Again, the choice is yours to make!
