It has been suggested by Dr. Halstead
that magnesium di-potassium EDTA could cause the blood of the
recipient to become more acidic, therefore making the chelating
effect of the EDTA less effective. To test this hypotheses, we
measured the ph of venous blood both before, and 40 minutes after a
365 mg magnesium di-potassium EDTA suppository.
The results were that the ph of the blood rose
from 7.37 to 7.66. Thus, contrary to Dr. Halstead's supposition,
magnesium di-potassium EDTA has an alkalizing, not an acidifying
effect on blood ph values. Since magnesium and potassium are both
alkaline elements, the alkaline result was to be expected.
