Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Birch (Betula species), including both the bark and leaves, has a history of traditional use in European and folk medicine, particularly for its purported antimicrobial, anti-inflammatory, and skin-soothing properties. In some traditional systems, birch extracts or decoctions were applied topically to treat various skin conditions, including wounds, rashes, and occasionally superficial infections like impetigo. The rationale was based on birch’s content of compounds such as betulin and betulinic acid, which are thought to possess mild antimicrobial properties.

However, scientific validation specifically for birch’s effectiveness against Staphylococcus aureus or Streptococcus pyogenes—the primary pathogens in impetigo—is limited and largely preclinical. A handful of laboratory studies demonstrate that birch extracts can inhibit the growth of certain bacteria in vitro, but clinical trials or robust animal studies targeting impetigo are lacking. Thus, the use of birch for impetigo remains primarily rooted in tradition, with only weak supporting evidence and no established role in modern medical practice for this indication.

Overall, while birch has a long-standing place in traditional skin remedies, its use for impetigo is not substantiated by strong scientific data, and should not be considered a replacement for proven medical treatments.
