How It Works

White oak bark has been traditionally used to help manage occasional loose stools, due to its astringent properties.

White oak bark's astringent actions stem from its rich source of tannins, active compounds that help tighten, strengthen and tone tissues lining the intestinal tract, potentially easing symptoms associated with occasional loose stools.

Tannins in white oak bark provide antioxidant activity, promote a healthy inflammatory response, and help combat foreign invaders that can cause intestinal upset such as loose stools.

White oak bark tannins can also help tone and tighten blood vessels, supporting healthy blood pressure and blood vessel function. They may also help relieve symptoms associated with varicose veins such as swelling and discomfort.

White oak bark has even been used in bath water to help soothe and shrink hemorrhoids.

Plus, white oak bark has been traditionally used to promote urine flow to help cleanse toxins and irritants from the body and support bladder and kidney health.

White oak bark contains various nutrients that support immune system activity, including vitamin B12, calcium, manganese, zinc, and polyphenols, including catechins that help combat foreign invaders and provide immunomodulatory effects.

Compounds in white oak bark, such as ellagitannins and roburins, act as antioxidants against free radicals and may support liver health.

Applied topically to the skin, white oak bark's astringent and antiseptic effects may help soothe itching and minor skin irritations and aid in the healing of minor cuts, burns and wounds.

Traditionally used as a gargle, white oak bark can help tighten gums and soothe mouth sores and sore throats.
