This article is from the Tinnitus FAQ, by email@example.com (Mark Bixby) with numerous contributions by others.
One contributor reports tinnitus relief from homeopathic cell salts:
I am a big believer in homeopathic cell salts. They have
help me tremendously in coping with the high input-output
life of a drummer. I perform approximately 12-15 hours a
week, full blast, which could take its toll (I'm 42) if I
wasn't taking care of myself.
For tinnitus, Kali Phos and Mag Phos for the nerves, Kali
Mur for any swelling in the inner ear. If I take the remedy
before retiring for the night, the symptoms are greatly
relieved by morning, and always within 48 hours.
These are generic names. There are several manufacturers,
notably Scheussler's Cell Salts (the guy who invented them
back in 1905), and Boiron out of France; Standard Homeopathy
here in the U.S.; all of which are usually available in most
health and nutrition stores.
You cannot overdose on homeopathic remedies, they are very
cheap ($5 for 150 doses), and extremely effective,
especially on acute conditions.
