Product Description

Wholesale Price Bulk Herbal Extract Natural Oak Bark Extract Powder 4:1 10:1

Oak bark extract is a natural ingredient derived from the bark of various oak species, primarily English oak (Quercus robur) and sessile oak (Quercus petraea). It has been used in traditional European herbal medicine for centuries due to its high content of tannins and other polyphenolic compounds.

Oak bark extract is a traditional herbal remedy valued for its astringent, antimicrobial, and antioxidant properties. It is primarily used for mild diarrhea, skin inflammations, and oral irritation, with emerging research supporting its potential in metabolic health and skincare applications.
