Most cases of acidity and gerd can be resolved by a following home-remedy.
Obtain sodium phosphate: phospo soda is available at all pharmacies and at walmart stores. It costs only just two or three dollars.
Put one drop of phospo soda in one liter water in a two liter empty soda water bottle. Shake-bang the bottle several times so just one drops gets evenly gets mixed up with water.
This process is called dynamization in homeopathy and this homemade medicine is equivalent to homeopathy grade naturm phosphate 6x.
Not you got 1 liter of medicine. Take just 3 drops it it after 1/2 hours of each meals and see the wonders of it.
Of-course you can purchase same medicine from homeoapthy vendors or websites for some hundreds of bucks, your choice but I cured my patients with this homemade naturm phosphoricum.
