                          Himalayan Birch
Scientific Name: Betula Utilis D Don

Introduction:
Betula utilis is a birch tree native to the Himalayas, growing at elevations up to 4,500 m (14,800 ft). The specific epithet, utilis, refers to the many uses of the different parts of the tree. The white, paper-like bark of the tree was used in ancient times for writing Sanskrit scriptures and texts. It is still used as paper for the writing of sacred mantras, with the bark placed in an amulet and worn for protection. Selected varieties are used for landscaping throughout the world, even while some areas of its native habitat are being lost due to overuse of the tree for firewood

Uses
The bark of Himalayan birch was used centuries ago in India as paper for writing lengthy scriptures and texts in Sanskrit and other scripts, particularly in historical Kashmir. Its use as paper for books is mentioned by early Sanskrit writers Kalidasa(c. 4th century CE), Sushruta (c. 3rd century CE), and Varahamihira (6th century CE). In the late 19th century, Kashmiri pandits reported all of their books were written on Himalayan birch bark until Akbar introduced paper in the 16th century.The Sanskrit word for the tree is bhûrja—sharing a similarity with other Indo-European words that provide the origin for the common name "birch".
The bark is still used for writing sacred mantras, which are placed in an amulet and worn around the neck for protection or blessing. This practice was mentioned as early as the 8th or 9th century CE, in the Lakshmi Tantra, a Pancaratra text.According to legend, the bark was also used as clothing by attendants of Lord Shiva.
The bark is widely used for packaging material (particularly butter), roof construction, umbrella covers, bandages, and more. The wood is used for bridge construction, and the foliage for fodder. The most widespread use is for firewood, which has caused large areas of habitat to be eliminated or reduced. Parts of the plant, including the fungal growth (bhurja-granthi) have also long been used in local traditional medicine.

Side effects
  • Skin growths from sun damage (actinic keratosis). Early research suggests that applying a birch bark ointment for 2 months to the affected areas can help clear actinic keratoses.
  • Arthritis.
  • Hair loss.
  • Rashes.
  • Conditions of the urinary tract.
  • Achy joints (rheumatism).
