This baking soda works great for cooking or for health reasons.  I take it for acid indigestion and heart burn.  Just a 1 tsp in a half glass of water and it's gone.  I use it to make my body more alkaline, so it's great for changing your pH level in your body!

Ex Output:
Positive


Ex Input:
Either I got 15 tubes that came from a bad batch lot or they are not selling the right Harissa. I bought 15 tubes thru Amazon from Parthenon Foods and used 4 of them so far and after putting the whole tube it still isn't spicy at all. Normally a whole tube would get you to sweat a bit!!!!! This seems to be a case of false representation. I buy these tubes in Canada at the grocery store all the time when I am up there and they provide a nice kick and spice (as they should). What's up with dat?

Ex Output:
Negative
