Birch
Betula
Betula, commonly known as birch, is a genus of trees and shrubs traditionally used in various herbal practices. While specific traditional uses for Betula species are not well-documented, they have been utilized in folk medicine across different cultures. Scientific evidence is limited but indicates that Siberian alder (a related species) can facilitate the growth of nearby dwarf birch by altering environmental stressors and affecting its radial growth patterns. A study optimized a method for extracting arylbutanoid and diarylheptanoid glycosides from Betula pubescens phloem, highlighting potential compounds of interest. Another study found that woody plant species diversity in Betula platyphylla forests decreased with increasing elevation, while soil properties significantly influenced community composition. Localized effects on soil moisture and nutrient ratios were observed within 2 meters around Betula spp. trees but not beyond in organo-mineral soils. No major safety concerns or drug interactions have been recorded for Betula species.

What the science says
- Siberian alder facilitated the growth of nearby dwarf birch by altering stressors and changing the seasonality of its radial growth.
- The study optimized a pressurized liquid extraction method for arylbutanoid and diarylheptanoid glycosides from Betula pubescens phloem.
- The study found that woody plant species diversity in Betula platyphylla forests decreased with increasing elevation, while soil properties significantly influenced community composition.
- Sparse natural colonization of Betula spp. trees had localized effects on soil moisture and nutrient ratios within 2 meters but not beyond, in organo-mineral soils.
- A sinusoidal-polynomial fitting model was developed using hyperspectral LiDAR data to characterize near-24-hour circadian rhythms in birch tree branches and leaves.
- The study found that Betula and Quercus tree pollen predictions had high accuracy, with R² values ranging from 0.69 to 0.92 and 0.71 to 0.89 respectively.
