Elevated methemoglobin levels reflect overly oxidized blood. Elevated urea or creatinine levels reflect kidney damage. Whenever higher than usual doses are to be administered, special attention must be applied regarding kidney damage especially if the urine is acidic

Acid renders the oxides of chlorine more reactive. Alkalinity stabilizes oxides of chlorine

Examples of chlorine dioxide quenching compounds are: N-acetyl-L-cysteine, glutathione, alpha-lipoic acid, ascorbic acid, polyphenols, tocopherols, bioflavonoids, anthocyanidins, benzaldehyde, cinnamaldehyde, juice concentrates and many herbal remedies. Most fruits especially grapes and berries are rich sources of polyphenolic antioxidants. Examples of herbs rich in antioxidant polyphenols are: chocolate, tea, coffee, turmeric, silymarin, licorice, ginkgo, olive. Sulfur rich foods also eliminate chlorine dioxide if present in the stomach at the time of treatment. Examples include: garlic, onion, leek, asparagus, beans, peas, egg, milk and even white potatoe (due to alpha-lipoic acid). Protein must also not be present in the stomach at the time of treatment. Proteins are made of amino acids which present an abundance of phenols, organic sulfides, thiols and secondary amines, which react with and eliminate chlorine dioxide on contact. L-tyrosine has a phenol group. L-methionine is a sulfide. L-cysteine is a thiol. L-tryptophan, L-proline and L-histidine have secondary amino groups. Certain B-complex vitamins are similarly reactive such as: thiamine, riboflavin, folate, pantothenate. Finally many drugs contain secondary amines, tertiary amines, thiols, sulfides or phenols.

Therefore, fruit, fruit juices, fruit concentrates, wines, green drinks, herbs, protein, most vitamins and most drugs should not be taken at the time of treatment and certainly not mixed with the acidified sodium chlorite solution.

for these successively reduced species of chlorine compounds to be successful in oxidizing the chlorite anion, they must remain in close proximity.

add sufficient acid to start the reaction but not overly increase the reacting volume.
