Americans will spend an estimated $5 billion this year on herbal supplements such as ginseng, ginkgo biloba and St. John’s wort. These and countless other over-the-counter medications are often used by people to self-treat everything from headaches and depression to high cholesterol and poor concentration. But be aware: Natural does not mean safe.
“Many patients assume that because a product is labeled ‘natural,’ it is perfectly safe,” said Jack Carter, M.D., anesthesiologist at Montclair Baptist Medical Center. “However, these substances can interact with prescription medications or anesthesia in unexpected or adverse ways.”
In fact, the American Society of Anesthesiologists cautions those who use herbal medications to stop taking these “natural” products prior to having surgery. Patients are advised to stop taking herbal medicines at least two to three weeks before surgery, since this is the amount of time it takes for most medications to clear out of the body.
“What we’re seeing as anesthesiologists is that patients who do not inform their doctors of their use of these supplements may be putting themselves at risk. Although all the information is not in on the dangers associated with the use of herbal products, we do not want our patients to take any unnecessary risks,” Dr. Carter said.
Researchers have noted serious health risks with herbal products including St. John’s wort, ginkgo biloba, and ginseng. St. John’s wort, which is often taken to treat anxiety, depression and sleep disorders, may intensify or prolong the effects of some narcotic drugs and anesthetic agents. Ginkgo biloba acts as an anticoagulant and may lead to excessive blood loss during surgery. Ginseng, a popular herbal supplement believed to increase vitality, may lead to episodes of high blood pressure and rapid beating of the heart.
If you are currently taking or are considering the use of herbal medications, here are some safety steps:
-Before trying a supplement, take a look at your diet and lifestyle and determine if changes in these areas could accomplish your health goals instead.
-Talk with your healthcare professional.
-Look for products with the words “standardized” for consistency. Check for warnings on packages.
-Stick to single-herb products, not combinations. The more herbs are combined, the more difficult it is to determine an individual herb’s effects.
-Stop taking supplements if there is a problem and see a physician.
If there is not enough time to stop your herbal medication before a surgery, bring the product, in its original container, to the hospital. This allows the anesthesiologist to see exactly what you are taking. (BHS)
