I've gotten 2 tiny bumps along the edge of my tongue.  Can anyone tell me
which ingredient(s) might be causing this?  I'm using Jason's Natural
Powersmile toothpaste.

Ingredients:

Calcium Carbonate, Glycerin Vege, Purified Spring Water, Sodium Cocoyl
Glutamate, Carrageenan, Aloe Barbadensis, Sodium Bicarbonate, Bamboo Powder
(whitener), Stevioside, Perilla Seed Extract, Parsley Extract, Silica,
Grapefruit Seed Extract, Peppermint

Thanks.
