White oak bark is used for its astringent properties and comes from the oak tree. This type of bark is native to England, however it has been cultivated in the United States. These trees can reach up to 100 feet in height and may live up to 1000 years. They are used for furniture making and their acorns were eaten regularly by Native Americans. In the past, acorns have been dried and turned into flour. Medicinally, white oak bark has several benefits.

The tannin in the white oak bark provides the strong astringent quality. Herbalists use this bark for improving skin health. They may also recommend white oak bark for ulcers, varicose veins, nosebleeds, digestive difficulties and strep throat. It works as an anti-inflammatory agent and contains minerals like zinc, calcium and manganese. Each Nature’s Sunshine capsule contains 460 mg of white oak bark.
