    Abstract: A method for producing a chewing gum with a controlled release traditional Chinese medicine active agent, as well as the chewing gum so produced, is obtained by physically modifying the release properties of the traditional Chinese medicine active agent by coating and drying. The traditional Chinese medicine active agent is coated by encapsulation, partially coated by agglomeration, entrapped by absorption, or treated by multiple steps of encapsulation, agglomeration, and absorption. The coated traditional Chinese medicine active agent is preferably then co-dried and particle sized to produce a release-modified traditional Chinese medicine active agent for use in chewing gum. The traditional Chinese medicine active agent may also be used in a coating on a chewing gum product, as part of a rolling compound applied to the chewing gum product, or as a part of the liquid in a liquid-center chewing gum product.
