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.

2. St. John's wort may cause you to break out in a rash; also avoid taking this herb without a physician's okay if you take monoamine oxidase inhibitors (Nardil, Parnate) or selective serotonin re-uptake inhibitors (Prozac, Zoloft) for depression.

3. Comfrey, chaparral, mistletoe and germander may cause altered liver function/hepatoxicity.
