For those following (if there are any!) two things to report. Both have been 'strong suspicion' but its time to note them as observations...
Between once a week and three times a fortnight, I take 3 x 30mg leaf extract tablets just on the one day for relief from tinnitus the following day (although curiously during the shorter of the winter daylight days it took two days)
Observation 1: During the Ginkgo day, the intensity of my usually mild T does increase. I had always taken the last one just before bedtime. Probably from unconsciously having realized this is the case
Observation 2: More than likely, I get more relief on day plus two or three after the targeted relief day, gratis if you will. I can't explain that. I don't believe my T is getting any better so perhaps the brain is replicating the earlier effect without being prompted. If that is the case, then that is an even stronger pointer that a cure (at least for some) lies in the compounds found in the Ginkgo leaf. But of course, at the moment effects are temporary and T sings loud today
