I think it was Dr J who I heard once describe it as toxic build up of some form.
The more common explanation is yeast.
I think it is a general sign of poor health in traditional Chinese medicine.
I brush my tounge routinely after my teeth, and when I'm really thorough with that, it will clear up for a day, but it always comes back.
Edit: bluelyme, I will try the baking soda and probiotic method. Thanks for sharing
