Quercus infectoria herb for inflammation
Galls of Quercus infectoria Olivier (Fagaceae) possess many therapeutic activities, with particular efficacy against inflammatory diseases. Quercus infectoria herb is used by herbalists in Thailand. This herb has a high content of tannins.

Aqueous extracts from seeds of Areca catechu L. (Arecaceae) (AC) and nutgalls
of Quercus infectoria Oliv. (Fagaceae) (QI) were investigated for their
hepatoprotective potential by studying their antioxidant capacity using four
different methods, by determining their in vitro anti-inflammatory activity
against 5-lipoxygenase, and by evaluating their hepatoprotective potential
against liver injury induced by carbon tetrachloride (CCl(4)) in rats. AC and QI
extracts exhibited potent antioxidant and anti-inflammatory activities.
Treatment of rats with AC and QI extracts reversed oxidative damage in hepatic
tissues induced by CCl(4). It is suggested that extracts rich in either
condensed or hydrolysable tannins and known for their potent antioxidant and
anti-inflammatory activities, may potentially confer protection against
oxidative stress-induced liver injury. These data should contribute to
evidence-based traditional medicines for anti-inflammatory and hepatoprotective
effects of both extracts.
Quercus infectoria herb research study
Detailed studies on Quercus infectoria Olivier (nutgalls) as an
alternative treatment for methicillin-resistant Staphylococcus aureus
infections.

Songkla University, Hat Yai, Songkhla, Thailand.
To investigate the antimethicillin-resistant Staphylococcus aureus (MRSA)
mechanism of Quercus infectoria (nutgalls) extract and its components. The
appearance of pseudomulticellular bacteria in the treated cells and the
synergistic effect of the Quercus infectoria plant extract with beta-lactamase-susceptible
penicillins suggest that the extract may interfere with staphylococcal enzymes
including autolysins and beta-lactamase. Our results provide scientific data on
the use of Quercus infectoria, which contains mainly tannin contents up to 70%
for the treatment of staphylococcal infections.
Quercus infectoria: a candidate for the control of methicillin-resistant
Staphylococcus aureus infections.
Phytother Res. 2008 April Chusri S, Voravuthikunchai SP. Department of
Microbiology, Faculty of Science, Prince of Songkla University, Hat Yai,

Acetone, ethyl acetate, 95% ethanol and aqueous extracts of Quercus infectoria
(Q. infectoria) demonstrated significant antibacterial activities against all
strains of methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-susceptible
Staphylococcus aureus (MSSA).
Quercus infectoria herb composition
Quercus infectoria has syringic acid. This plant extract also has a large amount
of polyphenols which have antioxidant properties.
