O/T Treatments or supplements for lung health

[Guest guest]

Does anyone know what supplements or treatments can help heal damaged lungs?

I'm asking this with respect to healing healing damage from smoking (for me, I

smoked years ago) and also for my DD whose lungs I think may have been damaged

by acid reflux as a baby (she had choking episodes for months as an infant

before becoming chronically congested).

I'm concerned about the flu & cold season and looking for anything that can

specifically help improve lung health.

Thanks,
