The leaves of E.americana extracted by maceration method for 6 days using ethanol 70%. Rats were divided into six groups of four animals each : exposed to ambient air (GroupA), exposed to cigarette smoke (Group B), exposed to cigarette smoke and treated with ethanol extract of E.americana leaves at dose 45mg/kg bw, 90mg/kg bw, 180mg/kg bw (Group C,D,E), exposed to cigarette smoke and treated with vitamin E dose 18mg/kg bb(Group F). All rats were treated for 14 days using 3 cigarettes non filtered each day by using a smoking chamber. After 14 days rats were killed. Right lungs were removed for histopathology. The results showed that dose 45mg/kg bw, 90mg/kg bw, 180mg/kg bw can reduce the level of lung damage to the enlarge of alveolar, thickening of the alveolar wall and inflammatory cell infiltration. Dose 180mg/kg bw as an effective dose to reduce the level of lung damage that compare to normal control.
