One of the longest nerves in the body is known as the vagus nerve (VN). The VN is the 10th pair of cranial nerves that originates at the brain stem in the medulla oblongata. This nerve is part of the parasympathetic nervous system, which is a part of the ANS. Research suggests ear acupuncture can activate the VN.
FDA Publishes New Guide on Supplement Labeling
The Food and Drug Administration's Office of Nutritional Products, Labeling and Dietary Supplements has posted a series of new guidelines on its Web site. Titled A Dietary Supplement Labeling Guide, the guidelines cover a variety of topics related to dietary supplements, including listing and placement of ingredients, health claims, and other issues, and are designed to present the agency's "current thinking" on the labeling of dietary supplements.

"This guidance document appears to be a very thorough review of the federal regulations that need to be considered when labeling a dietary supplement product," said Michael McGuffin, the president of the American Herbal Products Association. "This new guidance should be especially useful to companies that are new to the trade, but will also provide a helpful review for established firms."
The labeling guide is divided into eight chapters and six appendices, with the text in each chapter presented in a question-and-answer format. Topics of discussion include:
- General dietary supplement labeling
- Statement of identity
- Net quantity of contents
- Nutrition labeling
- Ingredient labeling
- Claims
- Premarket notification of new dietary ingredients
- Other labeling information
