To cure the flu you'll need to repeat this process two or more times at one or two hours intervals until there is no more bubbling when putting hp in ear(s). (I disagree, one time with 3 drops per ear is all you need - if there's no bubbling in one ear, you don't need to wait.
The bubbling isn't related to the degree of any illness or the killing of bacteria or viruses, it's the reaction of the H2O2 with the wax in the ear canal yielding O2 (bubbles), H2O water, and softened wax or wax in solution with the water. H2O2 applied in the ear of anyone with wax in their ear (regardless whether they are sick or not) will result in bubbling due to the reaction of the H2O2 with the wax...etc. It is not indicative of the H2O2 working on any bacterial or viral infection, it just shows you have wax in your ears!
In most cases, experimenting with H2O2 in ones ear won't hurt you, other than maybe drying out the skin in your ear canal, but if someone has any perforation of their tympanic membrane (ear drum), they could do further harm by pouring
anything in their ear no matter what it is. So be careful before you start trying this at home if you have any medical history w/ your ear canal or tymp. membrane.
Next, Cold & flu effects in ones throat & chest could not possibly be affected by administration of H2O2 to the ear. Unless one does have a perforated tympanic membrane (most of you should not), no solution/drops applied to the external ear canal would pass the tympanic membrane to get into the middle ear or eustachian tube to the sinuses or anywhere else, so unless the virus or bacteria that one is infected with is only present outside the tympanic membrane, H2O2 applied into the ear would have no systemic effects, no effects outside the external ear canal.
Next, even if there was no tympanic membrane, the H2O2 into the external ear would react and turn to water and oxygen before it made it far down the eustachian tube into the sinuses, but again, this speculation is pointless since the tympanic membrane IS there to block the passage into the ear. This is why when we have patients with middle ear infections (otitis media), we treat them with oral antibiotics, usually amoxicillin, 2nd generation cephalosporin such as cefuroxime, or trimethoprim-sulfamethoxazole, not with drops into the outer ear, because that is ineffective in all but localized external ear (otitis externa) infections like swimmers ear, which is usually due to Pseudomonas aeruginosa. Cold & flu infections are not external ear infections.
According to Dr. Simmons, contrary to what you may think or have been taught about how you catch the flu or the cold there is only one way that you can catch the two, and that's via the ear canal not through the eyes or nose or mouth as most have believed.
The idea of cold & flu bacteria & viruses only infecting you through your ears is simply incorrect... Nose & mouth.
If someone has "tubes in their ears", hydrogen peroxide
has been used as prophalaxys to keep the tubes opened if they become chronically blocked (blocked tympanostomy), as an option instead of removing and reinserting new tubes. Other than this and the usual removal of hardened ear wax, H2O2 poured in the ears is pretty much useless. If it makes one's cold or flu feel better, then go for it (placebo), but there is no medical reasoning for it.
