The birch tree (Betula spp.) is sought after for its wood, bark, leaves and sap. Birchwood was favoured by the First Nations of North America for canoe building because of its lightweight and flexibility. In Britain, the leaves were used to treat rheumatism and headaches, and the springtime sap was thought to be beneficial for the kidneys and bladder.
Birch sap was used by pioneers in North America as a springtime tonic, a gargle for sore throats, and a wash for skin conditions. Current applications for birch do not differ much from traditional uses, except new implications that support birch promotes healthy cell growth.
Health Benefits of Birch Tree Compounds
Birch and Unhealthy Cell Growth
Birch bark contains a variety of anti-inflammatory and apoptosis (controlled cell death) mediating substances such as betulinic acid, betulin, oleanolic acid, and lupeol, which may be beneficial in helping actinic keratosis (a precancerous skin condition). Lab studies have found that a chemical found in birch (betulic acid) can kill unhealthy cells. The human digestive tract cannot extract betulic acid directly, but, a fungus called chaga that grows on birch trees may bypass this difficulty.
Skin Support
Birch supports skin health because of its anti-inflammatory constituents, it is often added to cosmetic products to help reduce inflammation and redness in skin. It also helps regulate cell reproduction. Using birch extracts directly on the skin helps bypass the limited absorption in the digestive tract.
Joint Pain & Sores
Therapeutically, birch tree leaves have been used for joint pain taken both internally as tea, and used as an external rub. Birch extract applied topically is also helpful to heal and protect boils and sores.
Diuretic Properties
Birch sap contains chemicals that act as a diuretic, making it useful for urinary tract infections when combined with other herbs. Birch leaves contain salicylates (like aspirin), and therefore exhibit anti-inflammatory and pain-relieving properties.
How To Take Birch Tree Supplements
Birch supplements can be purchased as an encapsulated herb, raw herb or tincture. It may be found in combination supplements for urinary tract infections or kidney cleansing. Birch sap is often added to natural salves or creams to be rubbed onto painful joints and muscles. It can also be found in cosmetic products to help reduce inflammation and redness.
