Birch Bark Betula lenta by W.B.
Historically Birch tea made from the inner bark of Birch, is used as a remedy for gout, rheumatism, and dropsy. It is effective in eliminating kidney stones and is used as a blood purifier. The bark can also be used as a mouthwash, or as a remedy for diarrhea, dysentery, cholera infantum, bowel problems, and neuralgia. Applying Birch bark to sore muscles eases muscle pain, and helps heal sores, boils, and canker sores in the mouth. A decoction made from the bark is used in treating skin eruptions and dropsy. The oil is used on skin rashes such as eczema. Due to its diuretic quality, Birch leaf is used in treating cystitis and other urinary problems, rheumatism, gout, mild arthritic pain, and in expelling intestinal worms.
