Since the US Food and Drug Administration alerted several companies in April that their products are adulterated until they file New Dietary Ingredient notifications for DMAA — or 1, 3- dimethylamylamine — the dietary supplements community has been abuzz with opinions and reactions. An article in this issue of HerbalEGram discusses the controversial ingredient and recent actions taken against it. Additional articles report on the first Traditional Chinese Medicine product to obtain Traditional Herbal Registration in the European Union and the recent rise in cancer rates in Taiwan due to Aristolochic Acid (AA) toxicity. These stories are available in the Recent News section below.
The American Botanical Council recently alerted its members and the media to a new article that raises concerns about the apparent adulteration of some ingredients and products labeled as "grapefruit seed extract." This literature review — published in the most recent issue of ABC's quarterly, peer-reviewed journal HerbalGram — is part of a new non-profit consortium led by ABC, the American Herbal Pharmacopoeia, and the National Center for Natural Products Research. Meanwhile, ABC has added to its online catalog the audio and digital versions of a new text, A Guide to Pronouncing Plant Names by Judith Sims, which is available on ABC's website.
