the blueish tint is almost completely gone. i do not how long it was there- i guess 3-5 days. i have been using cayenne pepper for the longest time - at least 5 years. my tongue is now very pink ; there is no white coat at all.
i am thinking to do a liver cleanse and kidney cleanse before mid june. maybe that will help or perhaps as you wrote, the blue tint is just the detoxing.
fwiw- i do two types of pulling - vco (with oo and cayenne pepper) 20 minutes in the morning and clay mixed with cayenne pepper and oo (for 5 minutes) in the evening before sleep.
