Med08, here's a copy of a comment and question I asked in July which relates to your question. You may be able to find replies to it by searching for the conversation within this group. "Has anyone tried herbal support for immune system and lung health? Traditional Chinese medicine apparently includes several herbs which have been researched and found helpful as adjuncts to the typical NTM meds. Here's an article from NIH (link below). I don't have the expertise or patience to wade through all the technicalities of the studies, but found the results interesting, and wonder if anyone has tried any. The one I'm looking into is Astragalus membranaceus. I'm not interested in high dosages sold in capsules by various companies which may or may not be reliable; Astragalus can be consumed as a tea. Would love to know what others might have learned or tried."
