At of all the colon cleansers i have tried? and i cant remember all of them, but i have tried Dr schulze's and p&b shakes specifically...Now i do Lower bowel balance from Barefoot. And his is unlike any others ..it's so gentle like a natural bowel movement..I dunno if i would ever want to try anything else. I dunno what to do without his herbs if he no longer made them they are that good.
