White Tongue detox?

[Guest guest]

I vaguely remember some discussion awhile back about the tongue. Does

anyone remember what the determination was for a white coated tongue?

I remember the advice was to brush it, which I do, but for quite awhile

every day it's white and with really nothing to brush off.

Is the white tongue due to detox along the same lines as releasing

toxins through the skin?

Thank you,
