Taking supplements before or during surgery

I advise my patients who are planning surgery to quit supplements and any natural product — even natural teas — at least a week or 10 days before surgery.
Natural products are biologically active and could adversely affect your surgery and its outcome. Excessive bleeding is a big concern. I do not think that we really know to what extent supplements and natural products can play a detrimental role before, during or after surgery, but why would you take the risk? Here are some commonly used natural products that you should be very cautious about when going for surgery:
(I have taken these lists from NaturalDataBase.com- a very reliable source of information about nutritional supplements and herbs. Their work is very impressive. This is not hearsay data, but from a team of skilled pharmacists and other professionals.) These lists just give you an idea of what might occur. DO NOT assume that if you do not see your supplement or herb here that you are home free. No way!
Commonly used natural medicines that might affect platelet aggregation (Meaning the ability of your blood to clot.)
Andrographis – Based on in vitro and animal data

There are supplements that can stimulate such as bitter orange, caffeine (mate, guarana and cola nut) and DMMA (dimethyamlamine). They too should be stopped and I would want to know why you are taking them as well, if I were your physician.
These can adversely affect metabolism and should be stopped before surgery as well:
