Assuming the cause of your tinnitus is unknown after the most
scientific check-ups by your certified doctors, and you are still
having problems with your tinnitus, I would suggest you to at least try
gingko biloba.  I tried it, being prescribed by a doctor who graduated
from Cambridge University of England.  The use of gingko biloba
transformed my ear ring into drum ring or ringing on the ear drum
instead of ringing at the centre of my brain!  My doctor was delighted
because according to him the use of gingko biloba had helped some nerve
in my head recover.

It is my amateurish view that tinnitus in many, but not all, cases, is
a nerve ill! Nerve is in our head, and the way to help nerve recover is
through improved blood circulation in the head.  Gingko biloba has the
property of improving blood circulation in the head, which in turn
helps tinnitus provided the later is related to the nerve in the head.

Talk to your local pharmacist about the quantity used.  They have the
experience with many users of this product. Don't get scared by all
that alarming talks about brain bleeding.  Too much of anything causes
harm.  Thus the key is in moderation.

I am using the gingko pills made by Century 21 manufacturer in Arizona.
They are excellent products.  The recommended dosage is 2 a day for
one month and then one a day.  When I first started, I used 2 a day for
ONE day and then 1 a day up to now.  But talk to those who have
prescribed it or used it.  Buy the ones made of leafs.  You may find
some help there.  After all, if it does not help you, you can always
drop it.  It is totally non-addictive at all!
