Ginkgo Biloba is popular for its [cognitive benefits and memory improvement](/qa/what-are-the-best-plant-based-supplements-for-cognitive-enhancement-and-memory-improvement), but like any botanical, it's essential to understand its potential side effects and contraindications.

Common Side Effects

Based on extensive research, common side effects are generally mild and may include:

• Headaches
• Dizziness (Ginkgo may also interact with [plant-based medicines for managing vertigo and dizziness](/qa/what-are-the-best-plant-based-medicines-for-managing-vertigo-and-dizziness))
• Palpitations
• Gastrointestinal upset (nausea, diarrhea)

These side effects are often reported when starting a new dosage or when taking Ginkgo on an empty stomach.

Serious Concerns and Contraindications

More serious concerns, though rare, involve an increased risk of bleeding. This is crucial for certain individuals:

• Individuals on anticoagulant medications (blood thinners) such as warfarin, aspirin, or clopidogrel must avoid Ginkgo Biloba. It can significantly amplify their effects and lead to serious hemorrhagic events.
• Those with known bleeding disorders should avoid Ginkgo.
• Anyone preparing for surgery should discontinue Ginkgo at least two weeks prior to the procedure.

Who Should Avoid Ginkgo Biloba?

Several other groups should exercise caution or avoid Ginkgo due to potential risks or insufficient safety data:

• Pregnant or breastfeeding women: There isn't enough reliable information to confirm its safety during these periods.
• Individuals with a history of seizures: Ginkgo may lower the seizure threshold in some susceptible individuals, potentially interacting with [plant-based medicines for neurological support](/qa/how-to-choose-the-best-plant-based-remedies-for-restless-legs-syndrome-rls-relief-and-what-are-buyer-concerns).

• Those taking SSRI antidepressants: There's a potential for interaction, although the evidence is mixed.

Always consult with a healthcare professional before adding Ginkgo Biloba to your regimen, especially if you have pre-existing medical conditions or are taking other medications. This proactive approach ensures safety and helps determine if Ginkgo is the right choice for your health goals.
