possible interaction between ginkgo and trazodone (Desyrel)

There's a new concern about a possible interaction between ginkgo and trazodone (Desyrel).

There's already one report of an Alzheimer's patient becoming comatose a few days after starting both ginkgo and trazodone.

At this point, experts don't know for sure how common this interaction is...or how severely it affects most patients.
