I cannot be sure that OP is doing any cleaning my blood, however, I do know for a factoid that it does have its benefits. I had super sensitive teeth and within a week of OP daily in the a.m., they became noticably less sensitive...and I will let you know what the dentist has to say about the tooth he said will be needing a root canal. (I see him Tues morn.) I am not sure of what other benefits I am getting...yet... but if all I have to do is OP in the morning and have teeth that I can eat cold watermelon, breath in cold air, and rinse my mouth with whatever temp the water in the faucet happens to be after brushing and not be brought to my knees in pain...I'll do it. My gums are pink and healthy as well.
