Certified Organic Birch Extract
Also known as: Birch bark extract, Birch tar, Betulin, Betula pendula/pubescens extract
Overview
Birch bark extract, primarily derived from *Betula pendula* or *Betula pubescens*, is an herbal extract known for its medicinal properties. Key active compounds include betulin and betulinic acid. It is primarily used topically for wound care, particularly in conditions like epidermolysis bullosa, due to its anti-inflammatory, antimicrobial, and wound-healing characteristics. Emerging research also suggests potential applications in cancer prevention and chronic inflammation management. The extract is generally well-tolerated, with moderate to high-quality evidence, including randomized controlled trials, supporting its efficacy in accelerating wound healing. It is typically applied as a 10% topical formulation.
Benefits
Birch bark extract significantly accelerates wound healing, particularly in patients with dystrophic and junctional epidermolysis bullosa. Clinical trials, such as the EASE trial, have shown a significant increase in complete wound closure within 45 days compared to control gels, with sustained effects observed over 24 months. This benefit is clinically significant and supported by high-quality evidence. Beyond wound healing, birch bark extract shows potential in cancer prevention and chronic inflammation management, although more research is needed to confirm these effects and establish their clinical significance. Its anti-inflammatory and antimicrobial properties contribute to these observed and potential benefits.
How it works
Birch bark extract exerts its therapeutic effects primarily through anti-inflammatory and antimicrobial actions. The active compounds, betulin and betulinic acid, interact with the skin and immune systems to promote tissue repair and reduce infection. By modulating inflammatory pathways and inhibiting microbial growth, the extract facilitates a more conducive environment for wound closure. When applied topically, it achieves good local bioavailability, allowing the active compounds to directly influence the affected area and support the natural healing processes of the body.
Side effects
Birch bark extract is generally well-tolerated, especially when used topically. Most reported adverse events are mild to moderate. While specific common side effect percentages are not well-documented, potential uncommon side effects (1-5%) include mild skin irritation or allergic reactions at the application site. Rare side effects (<1%) are not well-documented. No significant drug interactions have been reported, and there are no documented contraindications for its use. It has been found safe for use in children aged 6 months and older with epidermolysis bullosa, indicating a favorable safety profile for this vulnerable population.
Dosage
For wound care, birch bark extract is typically used as a 10% extract in topical formulations, such as a gel. There is no established optimal or maximum safe dose for oral use, as its primary application is topical. When used for wound healing, it should be applied topically as needed. The topical absorption is considered sufficient for achieving local therapeutic effects. There are no documented required cofactors for its efficacy. It is important to note that this extract is primarily used for specific conditions like epidermolysis bullosa and should be used under medical guidance.
