French Oak Wood May Help Eliminate Toxins From The Liver
Drinking alcohol can lead to temporary hepatic damage, which can include nausea, fatigue, and tiredness. A recent study suggests that taking a French oak wood extract may help improve liver function by helping with the elimination of toxins.
Participants in the study included 44 healthy people with moderate functional hepatic failure due to alcohol. Characteristics included decreased albumin levels, increased total bilirubin, altered hepatic functions enzymes and increased oxidative stress. Over the course of 12 weeks, they were given either 300 mg of French oak wood extract or a placebo daily.
At the six-week mark, albumin levels had increased faster and higher in the supplement group compared to the control group. However, values between the groups were not significantly different at 12 weeks. Albumin is a protein produced by the liver, and decreased levels can indicate a problem.
The supplement group also had improvements in total bilirubin at the six-week mark, but not 12 weeks. However, the supplement group had significant improvements in direct bilirubin levels at the 12-week mark, when compared with the control. Bilirubin is a yellowish orange pigment that the liver creates when it breaks down hemoglobin. High levels of bilirubin can be a sign of liver damage, gallstones, cancer of the pancreas or gallbladder, and other infections.
The supplement group also had significantly larger decreases of the liver enzymes ALT-SGPT and AST-ASAT, when compared with the placebo group. Gamma GT values were at a normal level at six and 12 weeks in the supplement group, whereas the control group had smaller decreases and the numbers had not normalized by the end of the study.
Additionally, the supplement group had self-reported improvements in levels of tiredness and fatigue.
Researchers from Irvine3 Labs and D’Annunzio University conducted the study. It was published in the September 2016 issue of Minerva Gastroenterologia e Dietologica.
Compounds called roburins and other flavonoids unique to oak wood are the mechanisms behind the health benefits of French oak wood. Previous studies have found that French oak wood extract may help with tiredness and fatigue.
