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.
