Randomized clinical trial "olfactory dysfunction after COVID-19: olfactory rehabilitation therapy vs. intervention treatment with Palmitoylethanolamide and Luteolin": preliminary results.

Abstract

Treatment combining olfactory rehabilitation with oral supplementation with PEA and Luteolin was associated with improved recovery of olfactory function, most marked in those patients with longstanding olfactory dysfunction. Further studies are necessary to replicate these findings and to determine whether early intervention including olfactory rehabilitation and PEA+Luteolin oral supplement might prevent SARS-CoV-2 associated olfactory impairment.
