White birch

White birch is a deciduous hardwood tree with characteristic white satin bark and broad leaves. It is widespread in temperate and Boreal regions of the Northern Hemisphere. Its soft, flexible and waterproof bark was used by Native Americans to hand craft canoes, wigwam, bowls, bobbins and various everyday objects. In folk Native medicine, teas or beverages made from bark were considered as a remedy against digestive tract disorders (stomach pain, diarrhea). Salves and poultices from bark were traditionnally prepared for topical use to relieve skin wounding (bruises, burns) and other skin disorders (eczema, psoriasis, eruptions).; White birch cork is manily known its natural aspirin-like component (Methyl salicylate), and its resulting effects to soothe pain and inflammation. Thus, it is use in phytomedicine to treat fever, arthitris, rheumatism, gout and headache. In addition, it is said diuretic, promoting urine flow, preventing from cystitis, prostatis and kidneystones. Its diaphoretic properties help in overall body detoxification and fever reduction as well. Antibacterial and anti-viral health benefits have also been attributed to its cork.
