  • Patent number: 4991596
    Abstract: A smoking article includes a short, combustible, carbonaceous fuel element in a heat exchange relationship with a substrate carrying glycerin, tobacco extract, and a portion of an essential oil gland bearing plant. For example, fragments of cinnamon bark, lovage root, chamomile flowers or cardamon physically separate from the fuel element provide for a controlled release of a flavor profile during use of the smoking article. Heat provided by the burning fuel element acts to release essential oils from the glands to provide a complex flavor and aroma profile. The smoking article is capable of providing the user with many of the pleasures of smoking by heating but not necessarily burning tobacco.
