So people get a layman's explanation of this sodium bicarbonate thing. Can it kill covid? Yes. The same way you can die from dihydrogen monoxide poisoning (that's water).

The study doesn't recommend it as an ingested medication because their method of killing covid, with bicarbonate, would kill anything.

They effectively make the ONLY environment around the covid cells, bicarbonate, thus making it impossible for it to live. You could put an entire human in that situation and you would die.

It's not "two teaspoons in water". It's absolutely covering yourself inbicarbonate so you cannot eat, breathe or drink without ingesting lethal amounts.
