Henri:
I am doing so many different things for my health that it is hard to say for sure - I do know that I have never felt better, but I have also been taking a lot of spirulina and chlorella, zapping parasites, taking stuff for acid balance, health related paths modules and gotten into a fantastic weight lifting program.....;yet - if you study Ayervedic - according to this life science, the tongue is mapped by organ-locations — that is, "each section of the tongue is connected to the kidneys, lungs, spleen, liver, heart, pancreas, small intestines, stomach, colon, and spine.

Thus, an oil-mouth-massage soothes and stimulates the key meridians where taste meets organ. Simultaneously, as in any skin-massage, the inner skin and lining of the mouth, palate and tongue become warm and supple and the lubrication prevents dryness (the vatic effect)."

I have to say I have been to a Chinese Dr. on and off for years and so understand the implications of the health by looking at the tongue. Mine immediately changed after oil pulling, and at four months or so is a beautiful healthy pink color.

My suggestions is to try it. If only for one reason, my teeth are incredibly white and my gums are healthy!
