"In chronic sinusitis, antibiotics are of little or no benefit4. Clearly, addressing the underlying cause of chronic sinusitis (e.g. respiratory or food allergens) along with supportive therapy (e.g. saline nasal sprays, immune-enhancing herbs, and natural decongestants) appears to be the most rational approach." Joseph E. Pizzorno, Jr. is reporting on research reported by Dohlman, AW, in an article entitled "Subacute sinusitis. Are antimicrobials necessary?" in the Journal of Allergy Clin Immunol, 1993; 91: 1015-1023.
