Is it true that drinking calcium carbonate or potash extracted from wood ash can help with stomach acidity ? one of my friends told me this but i cant swallow it 😂

Both will partially neutralize hydrochloric acid in the stomach but I am not sure I would call that "help". A stomach is supposed to be very acidic. The burning sensation is acid leaking past the spincter muscle into the esophagus, not the stomach. I have used a little calcium bicarbonate in water to rinse acid out of the esophagus with success.


Calcium carbonate is the main ingredient in TUMS and most antacid pills.

Wood ash, however is going have more with potash, lye (Sodium/Potassium hydroxied. Calcium oxide.

Probably won't hurt you in small quantities, but tastes awful.

From wikipedia

Much wood ash contains calcium carbonate as its major component, representing 25[5] or even 45 percent.[6] Less than 10 percent is potash, and less than 1 percent phosphate; there are trace elements of iron, manganese, zinc, copper and some heavy metals.[5] However, these numbers vary, as combustion temperature is an important variable in determining wood ash composition.[3] All of these are, primarily, in the form of oxides.[3]
