Dosage - if you are undergoing radiation... A spoonful - hold it in your mouth, let it melt and swish it around for 2-3 minutes - then swallow (if you have open sores - it will sting - but it will help!!! ) - do this 4 times a day - - I used to do it 15 minutes before radiation - right after radiation - and then after meals... As it cleans - ask your dr. - of course - as for antioxidants - the main antioxidents they look at are selenium, and the vitamins a & c (or whatever letter) - the honey's doesn't have any of those. Goo luck!
