Firs (Abies) are a genus of 48–56 species of evergreen coniferous trees in thefamily Pinaceae. They are found through much of North and Central America,Europe, Asia, and North Africa, occurring in mountains over most of the range. Firs are most closely related to the genus Cedrus (cedar).
Firs are used as food plants by the caterpillars of some Lepidoptera species, including Chionodes abella (recorded on white fir), autumnal moth, conifer swift (a pest of balsam fir), the engrailed, grey pug, mottled umber, pine beauty and the tortrix moths Cydia illutana (whose caterpillars are recorded to feed on European silver fir cone scales) and C. duplicana (on European silver fir bark around injuries or canker).
Abies spectabilis or Talispatra is used in Ayurveda as an antitussive drug.
Fir is taken by mouth for respiratory tract pain and swelling (inflammation), colds,cough, bronchitis, fever, and sore mouth and throat. It is also taken for muscle and nerve pain, tendency toward infection, and tuberculosis.
Some people apply fir directly to the skin for muscle, nerve, and joint pain. It is also added to bathwater as a treatment for mental illness.
Fir might be safe for most people. The potential side effects of fir are not known.
