Been taking it since covid. RN friend of mines mom was prescribed it for her copd. It clears the lower lungs. Coughing only clears the upper lungs.
It obviously works because during covid amazon and others pulled it off their site/shelves. Then after the panic it quietly came back.
@TheChiefNerd Just gonna have to give the liberal women in offices that aren't building anything their cut of the money before a damn thing gets built.
