Although studies have not conclusively shown a significant effect of ginkgo on prothrombin time, activated partial thromboplastin time, or platelet aggregation, case reports have described bleeding events in patients using gingko biloba. Because of this, discontinuation prior to surgery is often recommended.
Whether ginkgo biloba is effective in the treatment of dizziness/vertigo is unclear. Although some studies have shown it to be helpful, others have not confirmed those findings. The same is true for its role in tinnitus. However, evidence does not suggest that its use significantly worsens or causes either condition.
Gingko seeds and fruit pulp are toxic. Contact or ingestion can result in an allergic skin reaction and/or potential convulsions. Because of its potential to lower the seizure threshold, patients with epilepsy and those who are prone to seizures should be especially careful when using gingko biloba.
