Caution
What is happening. Both are common in geriatric and cardiovascular use; combined antiplatelet effects are additive.
Mechanism. Ginkgo inhibits PAF; allicin and ajoene in garlic impair platelet aggregation.
Recommendation. Use together only with surgical and bleeding-risk awareness. Discontinue both 1 to 2 weeks before scheduled procedures.
