2 Tbsp. coconut oil
2 Tbps. baking soda
2 Tbsp. calcium magnesium powder
2 Tbps. xylitol or green stevia powder
2 tsp. real sea salt
20 drops essential oil (I use peppermint.)
10 drops trace minerals
My style recipe would simply read: equal parts coconut oil, baking soda, calcium/magnesium powder, xylitol with a dash of salt, a few drops trace minerals, and essential oils to taste.
