When should i take ginkgo biloba

Ginkgo is not always ginkgo

What is ginkgo?

Ginkgo (Ginkgo biloba) is a tree species that originated in China and is now planted around the world. In East Asia, the tree is cultivated for its edible seed and as a temple tree. Ginkgo biloba is one of the most intensively studied medicinal plants. For about 50 years there have been corresponding drugs that are used against dementia, dizziness, memory disorders and noises in the ears (tinnitus).

What ingredients does ginkgo contain?

The most important active ingredients in the leaf extracts are secondary plant substances such as flavonoids (e.g. quercetin), terpenoids, sitosterols and anthocyanins.

There are precise regulations in the European Pharmacopoeia for the production of a medicinal extract from gingko leaves. It is specified what percentage of the active ingredients, e.g. flavone glycosides, must be included. There is an upper limit for the undesirable ginkgol acid. In contrast, there is no standardized composition for foods and dietary supplements containing ginkgo. The individual products are therefore not comparable with one another.

Investigations by the Central Laboratory of German Pharmacists (ZL) also show that the majority of the food supplements examined contain ginkgo extracts for which there is a reasonable suspicion of the addition of secondary plant substances from other plant sources, e.g. quercetin and rutin from buckwheat or extracts Japanese pagoda tree.
