The Effect of Propolis on Nasal Mucosa
The Effect of Propolis in Healing Injured Nasal Mucosa: An Experimental Study
Research published in International Archives of Otorhinolaryngology in 2016 assessed the effect of propolis administration in healing injured nasal mucosa in rats. Eighteen rats were randomly divided into three equal experimental groups: (1) non-treated group; (2) gum tragacanth (suspending agent for propolis) treated group; and (3) propolis treated group. The non-treated group received no treatment for 15 days. The second group received gum tragacanth administration (5 ml/kg, orally) once daily for 15 days. The third group received propolis suspension orally at a dose of 100 mg/kg once daily for 15 days. The results showed a milder severity of inflammation and absence of ulcerations in the propolis treated group compared to the non-treated and gum tragacanth groups. In addition, goblet cell and ciliated cell loss were lower in patients treated with propolis than those without treatment and those treated with gum tragacanth. The authors demonstrated that propolis decreased inflammation and enhanced the healing of wounds of the nasal mucosa in rats.*
