Oak Bark/Corteza de Encino

Potential health benefits of oak bark
Helps soothe diarrhea: Oak bark's astringent properties, particularly ellagitannins, are thought to help strengthen the intestinal lining and reduce intestinal secretions, which can be helpful in easing diarrhea. Germany's Commission E recommends the internal use of oak bark for diarrhea.
Topical applications for skin issues: Oak bark is traditionally used to address skin conditions such as eczema, hemorrhoids, and wound healing. Its astringent nature may help reduce inflammation and bleeding, while its antiseptic properties can help prevent infection in cuts and scrapes.
Supports oral health: The astringent and antimicrobial properties of oak bark make it beneficial for oral care. It's been used in gargles and mouthwashes for bleeding gums, infections, and canker sores.
Scalp and hair health: Oak bark's astringent qualities can help reduce excess oil and soothe an itchy scalp. It is used in rinses for dandruff and to strengthen hair roots and add shine.
May help with varicose veins: Oak bark's toning and anti-inflammatory effects when consumed internally may help veins contract and reduce swelling associated with varicose veins.
Potential antioxidant activity: Some compounds in oak bark, like ellagitannins and roburins, are antioxidants that can help protect cells from damage caused by free radicals. This may contribute to potential benefits for heart and liver health, although more research is needed.
