Scientific Summary

Oak (Quercus robur) is a large deciduous tree whose bark is harvested for medicinal use. Its bark is rich in tannins that give astringent effects; it is traditionally applied to soothe digestive upset, mild coughs, and minor bleeding, and it is also used to support kidney and urinary tract health. Because of its strong astringency, oak bark can irritate the stomach, may contribute to kidney stones in susceptible individuals, and should be used cautiously by people with kidney disease or those on anticoagulant medications.
