Greetings, @honeydue! For me baking soda is miraculous!
To heal the throat is very effective, in addition to the mixture to make the gargle you recommend, I also prepare a mixture of soda, honey and lemon to make touches on the tonsils when they are inflamed. The cure is almost immediate.
Drinking water with bicarbonate to relieve stomach problems is a great recommendation and to detoxify the body takes a cup of warm water with a pinch of bicarbonate on an empty stomach. In addition to all these benefits, I have read repeatedly that consuming sodium bicarbonate is a natural remedy for cancer.
Grateful for this excellent publication, @honeydue. Thanks to @adsactly for spreading it.
