Warn patients who are on MAOIs that ginkgo can potentate their activity.
Limit ingestion of tyramine foods (cheeses, red wine) or sympathomimetic agents.
Warn patients that ginkgo is not a bronchodilator and is not a quick relief medication. Will not work in an acute attack.
The precise mechanism of action is unclear, but current research studies are encouraging.
There are several studies involving animals ongoing with respect to cognitive and neuroprotective effects
