[Treatment of equilibrium disorders with Ginkgo biloba extract. A multicenter double-blind drug vs. placebo study].

This study, conducted in 3 centres, included 70 patients with vertiginous syndrome of recent onset and undetermined origin. In a double-blind trial extending over a 3-month period they were given either Ginkgo biloba extract or a placebo. The effectiveness of Ginkgo biloba extract on the intensity, frequency and duration of the disorder was statistically significant. At the end of the trial, 47% of the patients treated were rid of their symptoms as against 18% of those who received the placebo.
