Note: Cedar (Cedrus spp.) should not be confused with Cryptomeria japonica (Japanese cedar), Thuja occidentalis (northern white cedar or eastern white cedar), Thuja plicata (western red cedar), or Juniperus spp. (mountain cedar or eastern red cedar) as they are not closely related. This monograph only includes information on Cedrus spp.
Cedar is native to the mountains of the western Himalayan and the Mediterranean regions. Because moths and other insects are repelled by the scent of the wood and oil, cedar wood has been used in closets and chests to preserve fabrics and textiles. In one clinical study, patients with alopecia areata who were massaged with a combination of cedarwood oil, other aromatic oils, and carrier oils had significantly improved symptoms. However, there are currently no further well- designed studies in humans available to support the use of cedar for any condition.
In atopic patients, cedar pollen may cause allergic symptoms, including asthma. Occupational exposure to cedar wood dust may have irritant, allergenic, or carcinogenic effects.
EvidenceDISCLAIMER: These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
Alopecia areata (hair loss):
Alopecia areata, a disorder in which the immune system attacks the hair follicles causing loss of hair on the scalp, face, and other parts of the body, is a difficult condition to treat. Massage with cedarwood in carrier oils may improve the symptoms of alopecia areata. However, additional studies are needed before a strong recommendation can be made.
