How do I Know if Herbal Supplements are Safe?

Safety should be a primary concern if you are thinking about purchasing or using herbal supplements. Herbal supplements come in a variety of forms, and some have shown benefit when taken. However, the US Food and Drug Administration (FDA) does not have the power to inspect or be certain that herbal supplements actually do what they claim. The official agency charged with setting standards of quality for dietary supplements, as well as over the counter and prescription medications is the United States Pharmacopeia (USP). This not-for-profit health organization sets standards that many countries throughout the world adhere to. The potential danger with using many herbs is that they have not been tested for safety or effectiveness, and many herbal supplements base their claims on anecdotal evidence only.

Unless herbal supplements have been shown to be unsafe, the FDA cannot pull these products from the market. Normally deaths or significant illness to several people must occur and be traceable to the herbal supplements before the FDA is empowered to act. Thus, one should consider the following when considering taking herbs:

  • Claims that sound too good to be true usually are. Even words like “tested,” “effective,” and “safe,” may be dubious marketing strategies.

  • Look for herbal supplements that are labeled USP Dietary Supplement Verified. This means the supplement meets certain standards in manufacturing, proper labeling of ingredients, and is free of toxic chemicals like lead.

  • Don’t assume that USP verification means the herbal supplements are safe for you to take.

  • Be wary of purchasing herbs manufactured outside of the US, since different standards may apply to production, ingredient strength and labeling.

  • If you are taking medications, be aware that herbal supplements may interact adversely with them.

  • If you are under 18 or over 65 be aware that herbal supplements may not have been tested on your age group.

  • If you plan to have surgery in the near future, you should know that certain herbal supplements can increase surgical bleeding or impact recovery time.

  • If you are pregnant or breastfeeding you should avoid all herbal supplements unless they are specifically recommended by a licensed physician.

    Generally, the best way to assure you are getting safe herbal supplements for your body is to check with a doctor regarding safety. If the doctor gives the okay after checking your medical history and any medications you might be taking, then using herbal supplements may provide a complementary way for you to maintain better health.

    It is certainly the case that some herbal supplements can be beneficial. To be safe, however, one should get the opinion of a licensed physician before taking herbs. Further, it helps to read scientific studies on the efficacy of certain herbs. Since scientists know that some herbal supplements have proven helpful, clinical studies on different herbs and vitamins take place with much greater frequency. Reading non-biased studies or summaries of clinical studies can also help you decide if certain herbal supplements will work, and if they are right for you.

    I find it disconcerting that you are recommending that someone check with a licensed physician before taking any herbal supplements.

    If you are talking about a medical doctor trained in the current health care system, the vast majority have not been trained in the use of herbal supplements and would not be an appropriate resource.

    A Master Herbalist/Naturopathic Doctor would have the training/eduction to advise. While unscrupulous practices by testing labs is unacceptable, how is it acceptable for pharmaceutical companies to "test" their own products and be permitted to market them? They can put drugs on the market knowing there may be injuries/deaths will but make enough money to cover any resulting lawsuits. How dishonest and deplorable?
