First, if you google only for "Tinnex", you'll find this: And that's not what this discussion is about, maybe someone can create another discussion for that machine if they like. Wikipedia's article on Caroverine is really short and doesn't even mention tinnitus directly: This discussion / change of emails is from the 1990s: http://stason.org/TULARC/health/body/tinnitus-ringing-ears/9-21-Treating-Tinnitus-caroverine.html Caroverine itself is an old drug. There is a clinical trial going, currently recruiting participants: http://clinicaltrials.gov/ct2/show/NCT01174979 Anybody heard anything else about this? This is getting quite a buzz on tinnitus sites since as far as I know the drug was recently approved in India. But I haven't heard of anyone getting the treatment yet... I will follow up in this thread if I myself find or hear more.
