Devices and methods for a palatal patch include a tablet or strip having a bioadhesive component and an active component. The bioadhesive component allows for the palatal patch to be attached to an upper palate, and for the active component to be released into the oral cavity and/or GI tract. Compositions for the active component include compositions for treatment of halitosis, anti-acids, vitamins, anti-smoking agents, and others. A composition for treatment of halitosis includes at least one of Echinacea, Lavender, Mastic Gum and Sage. A device for delivery of the palatal patch to the upper palate includes a housing and a piston, the piston having a holder for the palatal patch, and wherein the piston may be configured to move distally so as to delivery the palatal patch to the upper palate.
