Heard about this tea from a friend whose mom had major health issues. She's been using chaga mushroom tea for a while now and her medical condition improved so much that doctors couldn't believe. So I decided to try it since I've been suffering from stomach problems and pore immune system my whole life. So I ordered some chaga mushroom tea and started drinking it 3-4 times a day. My stomach problems disappeared within few days and I haven't been sick (cold and flu) for months now. I wish more people would know about this amazing tea.
