Materia Medica: Birch Bark

Botanical Description: Birch trees, belonging to the Betulaceae family, are deciduous hardwoods with distinctive bark that varies in color from white to silver, depending on the species. For medicinal purposes, Betula pendula (silver birch) and Betula lenta (sweet birch) are commonly employed. The bark is characterized by horizontal lenticels, giving it a unique appearance. The leaves are alternate, serrated, and ovate in shape, while the catkins, which appear in spring, consist of both male and female flowers. Birch trees are indigenous to temperate regions across North America, Europe, and Asia.
