Despite considerable research, the etiology and pathogenesis of Ménière’s disease remains controversial and undefined, although usually associated with allergic, genetic, or trauma sources, and with viral infections and/or immune system-mediated mechanisms. With treatment still unknown, our attention is towards the eventual impact of complementary dietary interventions, synthesizing the recent knowledge of some edible mushrooms and preparations on Ménière’s disease, which is a lifelong condition that can develop at any age, but most commonly emerges between 40 and 60 years of age. It is demonstrated that the oral administration of a biomass preparation, with 3 g/day of the mushroom Coriolus versicolor for 2 to 6 months, on some 40 human Ménière’s disease patients reduced systemic oxidative stress and cellular stress response, decreased the number of crises and their duration, and the frequency of symptoms, improving the clinical grading of tinnitus severity.

The Coriolus versicolor used in this clinical study was supplied by Mycology Research Laboratories Ltd.
