Birch (Betula species) has a longstanding history of use in traditional herbal medicine, particularly in Europe and parts of Asia, for the management of various skin issues, including external ulcerations. Traditional healers have employed birch bark, leaves, and extracts topically for wounds, ulcers, and other inflammatory skin conditions. The rationale behind its use is based largely on its purported antiseptic, astringent, and anti-inflammatory properties. Birch bark contains compounds such as betulin and betulinic acid, which have demonstrated antimicrobial and wound-healing activities in laboratory studies, though these effects have been more thoroughly investigated in vitro and in animal models rather than in clinical settings involving human ulcerations.

Despite its rich traditional use, modern clinical evidence supporting the efficacy of birch for external ulcerations is limited. There are a few preclinical studies suggesting that birch-derived compounds may promote wound healing and reduce inflammation, but well-designed human trials are lacking. Thus, while the use of birch in this context is justified by tradition and supported by some mechanistic or animal studies, it cannot yet be considered scientifically validated for the treatment of external ulcerations. Until more robust clinical evidence is available, its use should be approached as a complementary measure rooted in traditional practices rather than as a primary, evidence-based treatment.
