Used for eosinophilic conditions generally, including eosinophilic asthma, bronchitis and pneumonia. Eosinophilic conditions - white cells too active, without a real cause; our immune system (innate immune system I think I can say) gone wild as if a pathogen is present, but there isn't. (Or, in the case of COVID-19, too active not necessarily in the right places during an actual infection.) These conditions are very frequently missed, misdiagnosed or mistreated. They are not what your doctor first thinks about, but the modern explosion of inflammation has changed patient demographics dramatically since the time when your doctor was trained.
