Recently, Ginkgo biloba has been used to treat a variety
of health conditions, including asthma, bronchitis, fatigue, and tinnitus.
Some encouraging results have been seen from the studies of Alzheimer
disease/dementia, intermittent claudication, and tinnitus.
But a trial of more than 200 healthy adults older than 60 years
found that Ginkgo biloba taken
for 6 weeks did not improve memory. Side effects of Ginkgo biloba include
headache, nausea, GI upset, diarrhea, dizziness, or allergic skin
reactions. More severe allergic reactions have occasionally been
reported. There are some data to suggest that Ginkgo biloba can increase bleeding risk,
so people who take anticoagulant drugs, have bleeding disorders,
or have scheduled surgery or dental procedures should use caution.
