I have to say that it was less than 8months ago when I would've agreed with you and thought colonics were un neccesary, invasive and un natural; obviously my thoughts have changed. After doing much research (especially on the safety of colonics), I've changed my mind. For someone like me, with a lifelong battle of constipation (despite a frightfully healthy Diet of no processed foods and tons of fiber rich veggies),I decided that it was probably more unhealthy and toxic to not have regular bowel movements. After my fourth colonic (yes, I plan to complete a full series)my bowels seem to be improving and hopefully the candida will be making an exit very soon.
