At least one study has found that orally consuming oleuropein from powdered olive leaves reduced the airway influx of eosinophils and lymphocytes as well as IL-4 secretion in lung promoted by OVA inhalation or CS. In addition, oleuropein suppressed infiltration of macrophages and neutrophils through blocking OVA inhalation- and CS-promoted induction of ICAM-1, F4/80, CD68, and CD11b in airways. The researchers concluded that this may be a promising anti-inflammatory agent for asthma and COPD. This product has not been evaluated by the Food and Drug Administration.
