Nordic Birch, commonly known as silver birch or warty birch, is a species of tree in the family Betulaceae, native to Europe and parts of Asia, though in southern Europe it is only found at higher altitudes. Its range extends into Siberia, China and southwest Asia in the mountains of northern Turkey, the Caucasus and northern Iran. It has been introduced into North America, where it is known as the European white birch, and is considered invasive in some states in USA and in parts of Canada.
Nordic Birch is used in traditional medicine as a diuretic and is reputed to be useful in the treatment of high blood pressure, high cholesterol, obesity, gout, kidney stones,nephritis, cystitis, digestive disturbances and respiratory diseases. For these purposes, a decoction of the bark or leaves is generally used. Externally silver birch is used to promote healing, relieve pain and treat inflammations and infections of the skin such as eczema and psoriasis.
Birch Water also has an ever-expanding list of health and beauty benefits and boasts a rich nutritional profile, with high levels of electrolytes, potassium as well as vitamins B and C. It also contains Saponin, great for lowering cholesterol level, as well as Betuloside, which not only acts as a diuretic and detoxifying aid but helps flush out toxins from your body.
Birch is POSSIBLY SAFE for most adults when taken by mouth or applied to the skin for short periods of time.
Special Precautions & Warnings:
Pregnancy and breast-feeding: There is not enough reliable information about the safety of taking birch if you are pregnant or breast-feeding. Stay on the safe side and avoid use.
Allergy to wild carrot, mugwort, celery, and other spices: Birch pollen might cause allergies in people who are sensitive to wild carrot, mugwort, and celery. This has been called the “celery-carrot-mugwort-spice syndrome.” Birch pollen might also cause allergies in people who are sensitive to certain other plants, including apples, soybeans, hazelnuts, and peanuts.
High blood pressure: There is some concern that birch leaf might increase the amount of salt (sodium) that the body retains, and this can make high blood pressure worse.
Water pills (Diuretic drugs) interacts with BIRCH
Birch seems to work like “water pills” by causing the body to lose water. Taking birch along with other “water pills” might cause the body to lose too much water. Losing too much water can cause you to be dizzy and your blood pressure to go too low.
Some “water pills” include chlorothiazide (Diuril), chlorthalidone (Thalitone), furosemide (Lasix), hydrochlorothiazide (HCTZ, Hydrodiuril, Microzide), and others.
