My mother has been taking gingko biloba since last April, and so have I. We both find that our memory has improved. As for her tinnitus, she cannot say yet, but a few times lately she had the impression it completely stopped for a few seconds. She felt so strange about it, and it was such a short time she doesn't yet want to say it is improving. Also she's been doing an ear Reiki treatment daily since I attuned her in June.
A few years ago, on top of the normal ringing in the ears my mother started hearing from time to time what she described as 'explosions'. At night it was rather frightning as it would wake her up suddenly. I have a friend who makes vibrational essences and I gave my mother the one called Clairaudience, since I was not using it. The explosions stopped almost immediately. About 6 months after she finished the bottle they started again and I ordered a double size bottle. Again, as soon as she took the essence the explosions stopped and have never returned since.
Reiki to all
