Fir needles are believed to have the power to purify the air and the soul because of their disinfecting and calming properties. The burning of fir needles after childbirth was a common practice in the past, believed to impart good health for the mother and newborn. The pitch of the tree was also used to treat problems like menstrual irregularities.
