A nasal applicator tip for introducing a viscous medicament along internal nasal walls is provided. The nasal applicator tip may include an elongated tube extending from a base end to a socket end, wherein the socket end forms an enclosure having an opening, and wherein the base end is adapted to removably and fluidly connect to a source of viscous material. An applicator ball may be rotatably housed in the enclosure so as to protrude from the opening and allow viscous medicament to flow between its circumference and the enclosure. A user of the nasal applicator tip may removably attach it to a desired source of viscous material so that the user may selectively engage the protruding portion of the applicator ball and a predetermined portion of the nasal wall for medicating and/or moistening purposes.
