We're talking here about herbal supplements, a form of alternative medicine that more and more people are trying. Proper administration is
crucial, however, and a supplement labeled "natural" doesn't mean it's entirely safe and free of side effects.
In the Journal of Emergency Nursing, researcher Thomas Moss, MD, discusses some of the more popular herbal supplements and certain dangers associated with their use. He also recommends selecting herbs manufactured by reputable companies to ensure that you get a quality product.
1. Chamomile may cause an allergic reaction if you're sensitive to ragweed.
