Baking soda should not be taken everyday, it is only a temporary solution and that is getting into a lot of sodium content. The body needs a myriad of other alkaline minerals potassium being an important one as is magnesium. The drinking of crushed rocks and A_G is only a trick to maintain whilst the body is alkalyzing from other measures one has improved along with the consumption of those materials, mainly diet and lifestyle changes that accompany.
Baking soda 1-2 TBsp in enemas is very effective in temporarily alkalyzing and providing relief and cleansing of the bowel, the bicarbonate will have very quick effect, quicker and more effective than oral.
