Your coated tongue is telling you what is the actual state of your intestine. If you do not do any Bowel Cleanse and use o.o. on your tongue, you will get rid of it, but as soon as you start the woel cleanse it will resume... or as soon as you get a bad day or even when you simply do a cleanse the detox moves the toxins about and this will give you a coated tongue.
I liked to see my tongue coated because it meant that the probiotic intake were doing their job and the cleansing process was taking place.
