Can I drink herbal teas in the week before rhinoplasty and eyelid surgery?

Hello and thank you for your question.  The
best advice you can receive is from an in-person consultation.  I recommend avoiding herbal tea for 10 days prior to surgery, as this may lead to interference with blood clotting.   Make sure you specifically look
at before and after pictures of real patients who have had this surgery
performed by your surgeon and evaluate their results.   The most
important aspect is to find a surgeon you are comfortable with. I recommend
that you seek consultation with a qualified board-certified plastic surgeon who
can evaluate you in person.
Best wishes and good luck.

I would avoid taking all her bills supplements and vitamins for at least two weeks prior to surgery. These industries are essentially unregulated by the FDA. Therefore there could be many ingredients in them that are not even listed on the bottle. Some of those ingredients may cause problems with blood pressure or blood thinning. The inability to clot in a surgical procedure often leads to complications. It can take your body over one week to remake new platelets after taking a blood thinning medication.

Herbal teas often contain ginseng, and other ingredients that are blood thinners, or impair the clotting mechanism of blood.  I would avoid these, and most supplements for 10 days before surgery.
