Can you drink green tea before surgery?

The simple answer is the longer the better.   However, 2 weeks is usually sufficient.  Green tea has a mild anticoagulant effect which is beneficial in everyday life but not helpful in terms of surgery.  

Thank you for your question.  I ask my patient to stop taking any herbal medication 10 days before surgery.  This is because some herbal medication has blood thinning components which can make you bleed more in surgery.  If you can stop it would be beneficial however drinking in moderation should be fine.  All The Best
