Cedarwood belongs to the Pinaceae (conifer) botanical family.
1. The majority, up to 85%, of Cedarwood’s constituents are sesquiterpenes (alpha, beta, gamma himachalene, and cadinene). Sesquiterpenes are compounds that suppress microbial growth, oxygenate the brain, and have calming properties. In general, sesquiterepenes are soothing to tissues and work as liver and gland stimulants. Some may provide support for modulating pain and decreasing spasms. According to the EDR:
In the early 1990s, research from the universities of Berlin and Vienna showed that sesquiterepenes had the ability to cross the blood-brain barrier, with a specific affinity for the pineal and pituitary glands of the brain. These parts of the brain are important for melatonin and hormonal secretion. It was shown that these constituents had the ability to increase oxygenation to these and other parts of the brain by 28% (Nasel, 1992).
2. Cedarwood also contains sesquiterpene alcohols (alantol, alpha-caryophyllenol, beta-cubenol, cedrol, and cedrenol). These constituents are supportive to the immune system, prevent growth of pathogenic organisms, and assist with calming.
3. The final constituents of Cedarwood are sesquiterpene ketones (alpha and beta-alantones). Ketones support tissue and cellular health and assist with respiratory support.
Indications and summary of actions:
Due to its chemical constituents, cedarwood can provide support for skin issues, respiratory issues, protection from microbes, healthy sleeping patterns, hormonal balance, mood and emotional disturbances, and stress. With its high oxygen carrying capacity, cedarwood can support the cardiovascular system and it has been found to be helpful for hair loss!
Cedarwood was traditionally used for purification by the Native Americans. The Egyptians used this sacred oil for embalming their dead. It was used for medicine and incense in Tibet and has many references to healing in the Bible.
Cedarwood is well known to have a calming and sedative effect on the mood. Furthermore, Terry Friedman, MD, found that cedarwood was helpful in changing brain patterns of children with ADD and ADHD in a clinical study, though the sample size skewed its significance.
