See summaries below of recent scientific studies supporting the
efficacy of nasal washing:
A University of Wisconsin - Madison study recently followed participants
using the SinuCleanse® nasal wash system for six months,
and found the nasal wash provides an effective treatment for sinus
congestion. In the study, participants who added the nasal wash to
their daily regimen showed decreased symptoms, decreased medication
use and their overall health improved over the period of the study.
A study conducted by Werner Garavello, M.D.
at the University of Milano, followed 20 children (age 6
-12 yrs) with allergies and found that those who used the nasal wash
3 times a day for 6 weeks reported fewer symptoms and less antihistamine
use than those who were not using the saline.
A study conducted by John W. Georgitis at Wake
Forest University, Winston-Salem, N.C., followed 30 patients and found that nasal wash saline solutions
decreased inflammation of the nose better than other treatments and also lasted
several hours post-treatment.
A study conducted by Jose Subiza, M.D. with the
Department of Immunology, San Carlos Hospital in Madrid, Spain, followed 25 patients with grass
allergies over 8 weeks during pollen season, taking blood samples prior to the experiment
and afterwards. The study found that immunoglobulin levels in the blood of those using
the nasal wash did not rise as much as those who were not irrigating, showing that
those using the nasal wash had less immune system "stimulation" to the allergens.
A University of Wisconsin - Madison study recently followed
participants using the SinuCleanse® nasal wash system for 18 months
and found that nasal wash is an effective treatment for relieving chronic sinus
symptoms. This is the first study to follow participants using a nasal wash
system for a long period of time. Results of the study showed decreased sinus
symptoms, overall improved health and, particularly intriguing according to
the authors, a decreased use of sinus medication among nasal wash users.
