Hello, IP!
YES! Our entire family has has lots of success with hyd perox.. Hubby and I use it and have for some time now on our 6 & 8 year old..
We also take it internally.. There are only a few real 'miracle' cures (natural ones) I've used and hydrogen peroxide is one of them. It stopped the most horrible coughing (10-20 min 'fits' that lead to dry heaving, every hour for 3 nights solid) in SECONDS. I didn't have to take any more than one dose & I slept for 4 hours until morning.
Anyway... Can't recommend this substance (properly used!) more highly.. My other miracle 'cure' is Milk Thistle!
Blessings, Cam/EM
