What are some common adverse effects of ginkgo biloba?

Ginkgo biloba is a popular herbal supplement often used to enhance cognitive function and improve circulation. The common adverse effects associated with ginkgo biloba include mild gastrointestinal upset and headaches. These side effects are relatively minor compared to the potential benefits of the supplement, making them common complaints among users.

Mild gastrointestinal upset can manifest as nausea, diarrhea, or abdominal discomfort, and is typically not severe enough to warrant discontinuation of the supplement for most individuals. Headaches may occur as a response to changes in blood flow and circulation due to the properties of ginkgo biloba.

In contrast, some of the other options presented include side effects that are less frequently associated with ginkgo biloba, such as severe headache and nausea, which could be more indicative of an adverse reaction or interaction, rather than common effects seen in the general population. Options involving insomnia, anxiety, fatigue, and drowsiness also represent potential reactions related to other factors or medications rather than the common profile of side effects associated with ginkgo biloba.
