Pay close attention to any skin reaction of your lips, mouth and gums, as some people are sensitive to baking soda. I know I am (at least my skin is).
I found out when I tried to make my own natural deodorant using baking soda. I had been having such excellent results with all my natural products, that I was sure the baking soda natural deodorant would work great for me. Instead I got a very bad rash under my arms. Even when I reduced the proportion of baking soda significantly, I still got a rash. Lots of people use baking soda with no negative effects, and you might be one of them. However, I am beginning to wonder if people with EC are more sensitive than average?
( I did find a fantastic totally natural deodorant, so it all worked out in the end.)
