Hi @siliai, @poppins, @kjellis, my name is Nan and I read Stephen Buhner's book and tried his liquid tincture herbs about a year or so ago. He doesn't address MAC in particular but he did talk about mycobacterium a little so I tried the two herbs that were the closest I could find. Shari, @pfists also used these herbal antibiotics and she would probably be a little better at explaining. The two used were bidens and cryptolepis and I purchased them from a good website called Woodland Essence which is one of the websites that Stephen Buhner recommends. I mixed mine with juice and as I remember I did them two to three times a day. I don't have the book with me at the moment but maybe Shari could remember what pages he talks about these two. I think they're used for lots of different ailments. I am free of MAC now (just went to my pulmonologist and infectious disease doctor today actually) but I can't really say what worked and what didn't. I did the big three for one year from 2016-2017 and then after that I did the herbal antibiotics for a few months but that was it and for the past year and a half I have been doing the 7% saline solution. I'm a big believer in that saline solution. I'm also willing to try just about anything alternative. So that's been my experience. Hope that helps. Nan
