Ginkgo biloba is the only remaining member of the Ginkgoaceae family of plants and is used in traditional Chinese medicine and in alternative health supplements. Currently there is no evidence that these supplements are beneficial for any health condition.

The fruit and nuts of the plant contain ginkgolic acid, which can cause contact allergic dermatitis.

It also contains a ginkgotoxin, 4′-O-methylpyridoxine, which has been linked to a Vitamin B6 deficiency. As the toxin is structurally similar to vitamin B6 it interferes with biosynthesis, metabolism and function of vitamin B6 in the body and has been known to cause seizures and food poisoning type symptoms.

Pollen from the ginkgo biloba is a common trigger for allergic rhinitis.

When taken in small doses ginkgo biloba is considered to be a low FODMAP food. FODMAP stands for Fermentable oligosaccharides, disaccharides, monosaccharides and polyols. Foods high in FODMAPs can cause symptoms of food intolerance, affecting the gastro intestinal system and this can be mistaken for a true IgE food allergy.

You can read more about Food Intolerances on the dedicated Food Intolerance Page.

Ginkgo biloba is associated with contact allergic dermatitis. In some people it can cause a Vitamin B6 deficiency.

As it is not closely related to any other plants, ginkgo biloba is not currently associated with any cross reactivity.
