A Clinically Superior Product

When Otolaryngologist-Head and Neck Surgeon, Dr. Scott A. Cordray, developed LAVI Sinus Wash and LAVI Nasal Spray (formerly branded Oasis), he first had to prove to himself that the products were clinically superior to what he, as a practicing physician, would otherwise prescribe. He did so through two preliminary clinical studies, followed by two Level 1 Double-Blind Clinical Studies conducted by one of the world’s foremost Otolaryngologists – Dr. Michael Friedman. The results were significant.

The Science

The only sinus products made using purified Dead Sea salts, LAVI is clinically proven more effective than other salt or seawater and as effective as nasal steroids without the risk of steroid-related complications. The science is in the anti-inflammatory effect attributable to the composition and concentration of minerals found only in Dead Sea salts that reduce swelling and congestion.

The Clinical Proof

AS EFFECTIVE AS NASAL STEROIDS WITH SIGNIFICANT IMPROVEMENT OF SYMPTOMS.

Dead Sea salt irrigations vs saline irrigations with nasal steroids for symptomatic treatment of chronic rhinosinusitis: a randomized, prospective double-blind study. International Forum of Allergy & Rhinology Vol 2, No 3, May/June 2012 Pp 252:257.

OBJECTIVE: To compare the efficacy of nasal irrigations plus spray with Dead Sea salt (DSS) solution versus normal saline irrigation plus topical nasal steroid spray for the treatment of chronic sinonasal symptoms (CSS).

CONCLUSION: Treatment of chronic sinonasal symptoms with Dead Sea salt nasal irrigations and spray compared favorably to a regimen of normal saline and topical steroid spray and resulted in significant improvement of symptoms at four weeks without imposing the risk of established steroid-related complications.

DRAMATICALLY BETTER THAN OTHER SALINE.

A Randomized, Prospective, Double-Blind Study on the Efficacy of Dead Sea Salt Nasal Irrigations. Friedman, Ramakrishnan, Ninos. The Laryngoscope | 116 (June 2006, Pp 878-882).

OBJECTIVE: To compare nasal irrigation using mildly hypertonic Dead Sea salt (DSS) solution with hypertonic saline in the treatment of chronic rhinosinusitis and improvement of quality of life.

CONCLUSION: This study provides level 1 evidence on the superiority of Dead Sea salt over saline nasal irrigation for the treatment of chronic rhinosinusitis and only the group using Dead Sea salts showed improvement in quality of life based on the Standardized Rhinoconjunctivitis Quality of Life Questionnaire.

Other Scientific References

The Dead Sea is well established as a place of natural healing and relief from dermatological, muscular, rheumatic , and respiratory ailments. The science behind this tradition is owed to the Dead Sea’s mineral composition and concentration levels - up to four times greater than any other body of water. These mineral elements are the same ones naturally occurring in the human body and are essential for maintaining optimum health: magnesium, calcium, potassium, sodium — and more than 70 others.
