This article is from the Tinnitus FAQ, by firstname.lastname@example.org (Mark Bixby) with numerous contributions by others.
On p.32 of Conn's Current Therapy, 1994, W.B. Saunders Co., MDs Jack
C. Clemis and Sally McDonald write "The authors' choice for
pharmacotherapy is histamine. In a study awaiting publication, nearly
70% of patients treated with histamine achieved complete or partial
resolution of their symptoms."
Anyone with more information about this Therapy, the study to be
published, MDs Jack C. Clemis and Sally McDonald, and/or anyone else

to date no other information than that is in the above paragraph.
