Birch BarkIntroductionThe birch is a soft-wood tree native to cold, northerly climates. The name is a very ancient one, probably derived from the Sanskrit bhurga, meaning "tree whose bark is written upon." Birch bark easily peels from the tree, but is slow to decay. ConstituentsBetulinic acid, betulin, methyl salicylate. Parts UsedDried, powdered bark. Typical PreparationsTea, poultices. SummaryAntibacterial, antiviral, and anti-inflammatory, birch bark has been used to treat skin outbreaks for centuries. Recent investigations suggest that the chemical betulin found in the bark may be useful in the treatment of melanoma (although not as the sole treatment for the condition). Teas of the bark may also relieve joint pain associated with osteoarthritis, rheumatoid arthritis, or gout. PrecautionsBirch is diuretic. Do not take birch bark or leaf internally if you have difficulty going to the bathroom.
