Birch (Betula pendula) leaves and bark are rich in flavonoid glycosides (specifically hyperoside), saponins, and natural salicylates. These compounds act synergistically as an effective, non-irritating aquatic diuretic that stimulates the excretion of water and sodium without irritating the kidneys. The bark also contains betulinic acid, which possesses robust anti-inflammatory and skin-healing properties.
