The groups treated with propolis extracts exhibited considerable
ameliorative effects against asthma. Propolis has flavonoids and phenolics, which may have antioxidative
effects, thus explaining that result. Otherwise, the sensitised
and honey or royal jelly treated groups showed an increase
in asthma cascade events by increasing the inflammatory cells.
These results might be due to the immunostimulatory and
vasodilatory effects of royal jelly and honey, which are antagonistic
to bronchial asthma cases.
