Could herbal supplements affect my mother's ability to drive?
My mother often buys herbal supplements at the health food store. She believes the manufacturers' extravagant claims and is always eager to try the latest "all-natural" miracle cure. Her nonprescription pill popping has always seemed harmless to me, but recently a friend mentioned that herbal products could affect her driving ability. So far my mother hasn't had any driving problems, but I can't help worrying about her.
Expert Answer
You're right to be concerned. Many people don't realize that even though herbal supplements can be purchased without a prescription, they can still have serious side effects. Just like other drugs, herbal supplements can affect a person's physical and mental condition -- and that includes her ability to drive safely.
One reason that herbal supplements pose a health risk is that manufacturers aren't required to meet the same safety standards that regulate over-the-counter and prescription medications. As a result, a number of herbal supplements have been found to be dangerous only after they've been on the market for some time.
Herbal supplements can also interact with other medications and cause serious health problems. Seniors may be at particular risk because they commonly take a range of different medications. Also, as people age, it takes longer for their bodies to metabolize drugs and other substances and eliminate them from their bodies.
