Uses
birch bark extract is described as having anti-irritant and antiseptic properties, and effective in acne treatment. It is used to make sunburn products, soothing lotions, and aftershaves. The oil is astringent and is mainly used for its curative effects, especially in cases of acne and eczema. In folkloric medicine, birch bark extract was considered good for bathing skin eruptions. Destructive distillation of the bark’s white epidermis yields an empyreumatic oil known as oil of birch tar, Oleum rusci, or dagget. This is a thick, bituminous, brownish-black liquid with a pungent, balsamic odor. It contains a high percentage of methylsalicilate, creosol, and guaiacol and is almost identical to wintergreen oil.
