Gingko biloba: An herb that is very popular as a treatment for dementia (a progressive brain dysfunction) and to improve thinking. Research demonstrates some support for the use of gingko for the following conditions: dementia and Alzheimer's disease, intermittent claudication, glaucoma, memory enhancement, macular degeneration, tinnitus, and Raynaud's phenomenon.
Gingko seems also to have blood thinning properties. Therefore, it is not recommended to be taken with aspirin, nonsteroidal anti-inflammatory drugs (such as ibuprofen/Advil, Motrin or naproxen/Aleve), or medications to prevent blood clotting (anticoagulants) such as warfarin/Coumadin. Gingko should be avoided in patients with epilepsy taking seizure medicines, such as phenytoin /Dilantin, carbamazepine/Tegretol, and phenobarbital. Also, antidepressants, medications for hypertension, medications to lower blood sugar, cyclosporine, and thiazide diuretics.
