Plant Story
White oak (Quercus alba) is a long-lived, native North American plant. It is cultivated as an ornamental plant or used to make barrels for the aging of wine. White oak has been used medicinally by several native North American tribes for its antiseptic and astringent properties. The bark was boiled and the liquid was used for the treatment of bleeding piles and diarrhea, intermittent fevers, coughs and colds, asthma, and lost voice. The bark has also been chewed as a treatment for mouth sores. Externally, it was used as a wash for skin eruptions, burns, rashes, bruises, and ulcers.
White oak is a source of phenolic compounds especially ellagitannins, which have demonstrated various biological activities, such as anti-oxidant, anti-inflammatory, and anti-microbial properties. In a study that investigated 35 medicinal plants known to be used by the Indigenous Peoples of the North American boreal forest, white oak was found to have strong anti-oxidant activity based on DPPH, NBT/XO, and DCF/AAPH assays.
