Ginkgo Scientific Trial
A double blind controlled trial of the use of Ginkgo Biloba in the treatment
of tinnitus involving 1000 people has been conducted by Dr Ewart Davies
and Shelly Drew of the department of pharmacology, University of Birmingham,
UK.
500 people were given Gingko, and 500 people were given an inert substance
that looks and tastes like gingko. The term "Double blind" trial means
that neither the experimenter nor the subject knows who is taking the real
drug and who isn't. This means that the results aren't influenced by
the person's knowledge and the effectiveness of the drug can be compared
with the placebo. Using a code, the identity of those who have taken
the drug, and those who have taken the placebo, is revealed after the
results have been collected.
Here are the intermediate results of the Ginkgo trial.
Gingko Trial over 12 weeks with 1280 participants:
4 weeks into treatment (1008 replies): 73% unchanged; 7% improved;
20% louder!! About half of the people in the above are taking a placebo pill, while the other half are taking ginkgo extract. It has not yet been revealed which person has taken which as this might bias the interpretation of the results.
