@sueinmn I saw that Amazon Pharmacy sells vials of 7% saline mixed with hyaluronic acid. I remember reading here some members buy their 7% saline on Amazon, so I wondered if some of them experienced with the combo and which effects they noticed. Since it is a combo, of course it is no longer 7% saline, it is diluted. I brought it up to my pneumologist but he did not seem interested at the time. I will bring it up again. I have been taking on my own decision a supplement of liposomal high molecular weight HLA, which I have found quite helpful for my lungs with other benefits. I mentioned it to my ID doc who told me at the time: "take it if you want, it won't change anything". Well it did.
Wishes of great health to all!
