>> Lite Salt put out by Morton that is 290mg of sodium to 350mg potassium.
Don't know about that but the ratio sounds fine.
However Gerson was very concerned about death due to cranial pressure and therefore disallowed all salt.
I managed to get by with a similar mix, it appears that as long as the electrolites are balanced Sodium/Potassium the swelling is non existant. If however that doesn't help then eliminate the salt.
