Good thing I noticed this on webmd:
Some medications are changed and broken down by the liver. Ginkgo might decrease how quickly the liver breaks down some medications. Taking ginkgo along with some medications that are changed by the liver might increase the effects and side effects of some medications. Before taking ginkgo talk to your healthcare provider if you take any medications that are changed by the liver. Some of these medications that are changed by the liver include clozapine (Clozaril), … haloperidol (Haldol)
The same thing with gingeng
Do your research!
