* Since herbs such as antidepressants (Wellbutrin, Zyban) or antibiotics (Penicillin, Theophylline, Cephalosphorin, Corticosteroids, Methylphenidate) may increase the risk of seizures. Same with Insulin and other diabetic drugs (Glucophage, Glynase), they should not be used with such medication to prevent seizures.
* Cyclosporine should be avoided also since it has the same effects as Gingko and may decrease the effect of the drug.
* Drugs like Thiazide diuretics, Chlorothiazide, Hydrochlorothiazide should be avoided as they can increase high blood pressure in some people.
* Roasted ginkgo seeds may cause diarrhea, nausea and vomiting, indigestion or or allergic skin reactions.
* Fresh ginkgo seeds may cause difficulty in breathing, unconsciousness, and worst, death.
