what supplements should be avoided before surgery
Herbal supplements, in general, are to be avoided prior to surgery because they can cause bleeding or other operative complications. A few commonly taken herbal supplements to avoid are: Ginko Biloba, Garlic, Ginseng, Ginger, Dong Quai, Ephedra, Feverfew, St. John's Wort and/or Omega 3 fatty acids.
Most surgeons will instruct you to avoid preparations with Vitamin E before surgery, however, so it is important to check your dietary supplements/multivitamin carefully. However, after the surgery, your health care professional may indicate that Vitamin E may be appropriate.
