Earlobe 20-18 question?

My mom is in her 70's and she was dogged by this ringing in her ears for about 5 years. Her doc said she would have to live with it, and then a friend told her about this holistic cure. Mom was old school, and she didn't want to consider it, but I sneaked a copy of this book for her, and I read it to her! I made her try it, and 5 months later it was almost gone. It was like Wow !
