Anna has the best herbs to treat bronchitis. I took her herbal prescription and I noticed right away that my coughing is 100% better from 1 month of coughing from bronchitis. I got sick again and took the pills and got better faster than normal the second time. I am a firm believer in her treatments! I have Grave’s Disease and my immunity is at stake here. When I get the common cold/flu, it's 10 times worse for me. My endocrinologist didn't give me much to go on, so I have to treat myself. Thank you, An, for guiding me on how to feel better.
