NAC (N-Acetylcysteine)
(Obviously speak to her doctor first in case she's on something that might conflict but I've used this myself)
I grew up with asthma and adding NAC to my regimen made a huge difference. It's anti-inflammatory for the lungs and airways and helps break up mucus.
Extremely helpful for asthma and even COPD.
Do your own research but the benefits are there.
@BrandonTierney Come on BT. Overpaying? He signed for a little more than what that bum Williams signed for with the Mets. This makes the Mets a demonstrably worse off team. No way the Mets can compete with the Dodgers. Stearns is clueless
