<<Disclaimer: Verify this information before applying it to your situation.>> Several people on the list have recommended Penzey's as a good place to find gf spices. http://www.penzeys.com/ In addition, I received the following email from Spice Islands: --------------------------------------- Straight spices and herbs, such as Basil Leaf and Ground Oregano are inherently gluten free. In following recomendations of the Food Allergy Network, Tone Brothers Inc., does not provide a gluten free product list. Such lists become inaccurate very quickly due to constantly changing nature of food manufacturing. Our labels represent the most current information available. Concerning your question of anti-caking agents, if an anti-caking agent is used, it is listed on the ingredient statement. This is mandated by Federal Law. If you have questions on particular spice blends (more than just a spice or herb), please feel free to call our SpiceAdvice line at 800-247-5251 during the hours of 9am - 4pm CST., Monday through Friday.
