People should assess risks before using herbal supplements Published Aug. 9, 2007 By Pamela J. Doherty 88th Aerospace Medicine Squadron WRIGHT-PATTERSON AIR FORCE BASE -- Today, many people take herbal supplements -- a type of dietary supplement that contains herbs, either singly or in mixtures. An herb, also called a botanical, is a plant or plant part used for its scent, flavor and/or therapeutic properties. Hundreds of these herbal products and supplements are available. They are advertised to just treat about any symptom; however, trustworthy evidence usually doesn't exist to support these advertising claims. Sales of herbal supplements surged in the 1990s, but have recently declined, possibly in response to news reports about safety problems and lack of effectiveness. But their use remains widespread and the importance of accurate information continues to be paramount. If you are considering buying a herbal remedy or supplement, consult the "Buyer's Guide to Herbs and Supplements" to learn as much as you can before you buy. Many herbs have a long history of use and of claimed health benefits; however, some herbs have caused health problems for users. Unlike prescription and over-the-counter medicines, herbal products and supplements don't have to be tested to prove they work well and are safe before they are sold. They also may not be pure; they may contain other ingredients, such as plant pollen, that could make you sick. Further, sometimes supplements contain drugs that aren't listed on the label, such as steroids or estrogens. Some of these products may even contain toxic or poisonous substances, such as arsenic, mercury, lead and pesticides. In the United States, herbal and other dietary supplements are regulated by the U. S. Food and Drug Administration as food. This means that they do not have to meet the same standards as drugs and over-the-counter medications for proof of safety, effectiveness, and what the FDA calls "good manufacturing practices." If you use herbal supplements, it is best to do so under the guidance of a medical professional who has been properly trained in herbal medicine This is especially important for herbs that are part of a whole medical system, such as traditional Chinese medicine or Ayurvedic medicine. You should be especially cautious about using herbal health products or supplements if you take any drugs to help treat depression, anxiety, seizures, blood thinning, blood pressure or any other heart medications. If you are using diabetic or cancer drugs, use extreme caution. Other risk factors when using herbal supplements may include glucosamine that contains sodium and can affect you differently if you are following a low-sodium diet. People who are allergic to shellfish may also be allergic to glucosamine related to ingredient. Another risk involves the use of kava products. People should not drink alcohol if they take these products. Kava can increase the affects of alcohol. Remember "natural" does not necessarily mean "safe."
