Alternative therapy in pruritus

Because of its multitude of origins, the symptom complex of pruritus has a plethora of purported remedies and few therapeutic indications. Very few topical and systemic FDA approved medications have the indication of pruritus. Specific therapy still awaits a better definition of the exact physiologic events in chronic pruritus. Hence most medications actually focus on the central nervous system--the peripheral receptors--and the lack of specific physiologic targets has inhibited pharmacologic development. The resulting gap has opened the door to a variety of alternative therapies.
