Himalayan birch
Betula alnoides
Betula alnoides is a tree traditionally found in East Asia. While there are no specific traditional uses recorded for this plant, it has been observed that mixing Betula alnoides with Castanopsis hystrix can increase the number and density of branches, particularly at a 1:3 or 1:5 ratio. Scientific evidence suggests that under future climate scenarios, suitable habitats for Betula alnoides are projected to shift northwestward by 2050, indicating significant distribution changes due to climate change. The bark of Betula alnoides contains notable levels of phenolic and flavonoid compounds, showing moderate cytotoxicity, which may indicate potential medicinal applications but requires further research. No major safety issues or drug interactions have been recorded for this plant.
