To test their theory, they randomly assigned mice into four groups: a control group; a group given with 1.8 grams per kilogram (g/kg) of alcohol; a group treated with 0.2 g/kg dose of bitter ginger extract and alcohol; and a group treated with 0.4 g/kg dose of bitter ginger extract and alcohol. The treatments were given orally once a day for 14 days, 30 minutes before alcohol exposure. After that, they performed biochemical tests to assess blood and brain homogenate and collected brain tissue samples for histological investigation.
Based on the results, even though both doses of the bitter ginger extract significantly reduced the levels of malondialdehyde (MDA) and protein carbonyl in the brain homogenate, the 0.4 g/kg dose was more effective in preventing ethanol-induced brain damage than the 0.2 g/kg dose. The reductions in the levels of MDA and protein carbonyl may be attributed to the high level of zerumbone present in the bitter ginger extract. MDA is a biomarker of oxidative stress, while protein carbonyl is an indicator of protein damage after alcohol consumption.
In addition, both doses of extracts reduced oxidative stress by increasing serum levels of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) activities and glutathione (GSH) level.
Furthermore, histological analysis revealed that the extract of bitter ginger suppressed the loss of the nerve cells in the cerebellum cortex called Purkinje cells and retained the amount and shape of the cells.
In conclusion, the findings of the study suggested that the extract of bitter ginger can protect the brain from damages caused by alcohol.
Another body organ that is often negatively affected by alcohol consumption is the liver. The good thing is that the damage can still be reversed with diet, as long as it has not progressed too far. You can reverse the detrimental effects of alcohol by following this diet:
