Due to the content of ginkgolic acids, which are potent contact allergens, an allergic risk is not ruled out.

[Ed.note: This applies to various preparations made from the whole leaf. The approved standardized extract has had the ginkgolic acids reduced. For more on this subject, see Ginkgo section in the Introduction.


Since the efficacy of the above preparations for their listed indications has not been confirmed, no therapeutic application is approved.
