Background: At present, the state-of-the-art medication in treating idiopathic taste disorder (gustatory dysfunction) is zinc. If zinc medication was unsuccessful, not tolerated or if it is contraindicated the persons aff ected can hardly be helped. Objectives: In a randomized placebo-controlled clinical trial an attempt was made to determine the effi cacy of acupuncture. Methods: The treatment group was treated with acupuncture needles, the placebo group with an inactive acupuncture-laser. Endpoints of the study were changes in the taste test, the quality of life and the severity of symptoms of depression (BDI) as well as mood changes (ZMS). Satisfaction with the success of the respective therapy was also evaluated. Data were collected before and after therapy and again for the treatment group 10 weeks after completion of the treatment period. Findings: Treatment with real acupuncture showed a signifi cant improvement in gustatory function as well as asignifi cant improvement in psychological symptoms. Greater satisfaction with the treatment results was evident in the treatment group. The treatment results of acupuncture remained stable over a period of ten weeks after completion of the treatment. Conclusion: Acupuncture was eff ective in the therapy of idiopathic taste disorders and therefore it is an eff ective alternative when zinc medication is not tolerated or unsuccessful. But it is also suitable as a therapy of fi rst choice. Acupuncture can be considered as an extension of the therapeutic spectrum in the diffi cult treatment of taste disorders.
