Tried ACV for my 5-year-old's asthma. 1TBS in warm water with honey once a day. I am sorry to report that it didn't help him at all. He was on it for 2 months and during that time got several flares and even wound up in the ER with a severe attack. After that we gave up and he's now on Flovent and Singulair and doing much better. I am very bummed out to have him on these medications and would love to find something natural, but so far no luck. Will keep researching alternatives.
