If you are taking St. John's Wort or any other herbal supplements, you need to tell your doctor before heading into the operating room. By not informing them before your surgery, those natural supplements can have dangerous consequences.
Finding natural ways to boost the body's defenses isn't always bad. But before you take those over-the- counter products, make sure you know what's in them before you go into surgery. Studies show that as much as 60 to 70 percent of patients don't disclose their herbal use with their physician. Some patients may think since they are natural supplements they are not considered medications.
