Birch Bark
Also known as- Betula spp, Betula, Betulae Folium, Betula Pendula, Betula Verrucosa, Downy Birch, Silver Birch, White Birch.
Introduction
The 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.
Constituents
Betulinic acid, betulin, methyl salicylate.
Parts Used
Dried, powdered bark.
Typical Preparations
Tea, poultices.
Summary
Antibacterial, 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.
Precautions
Birch is diuretic. Do not take birch bark or leaf internally if you have difficulty going to the bathroom.
