A rat study found that inhaling cedarwood oil affects the olfactory and other organ systems (3). When you inhale the faint scent of such essential oils, a signal is transmitted to the limbic and hypothalamici It refers to the hypothalamus which serves as the primary connection between the nervous system and the hormone system. areas of your brain via your nose (olfactory system). Such signals stimulate your brain to release neurotransmitters such as serotonin and endorphins. These chemicals, in turn, induce a sense of calm and relaxation (4).

Massaging essential oils onto your scalp has the potential to reduce alopecia (hair regression). This exercise increases blood flow to the hair follicles, conditions the scalp, and enhances the strength of the roots. It reduces conditions that can interrupt the process of hair growth, including dandruff and dry scalp (6). In a seven-month randomized trial with 86 individuals with alopecia, the test group received a daily massage with essential oils of lavender, cedarwood, thyme, and rosemary in jojoba and grapeseed carrier oils (6). This group showed about 44% improvement in hair growth parameters in contrast to only 15% in the control group. These essential oils may also relieve headaches and normalize sleep patterns when massaged regularly (6).

Cedrol has potent insect and pest repelling properties. Insects like red ants, black-legged ticks, moths, and carpet beetles were all either killed or showed acute toxicity symptoms when exposed to cedarwood oil (8).

When wood blocks were treated with oils of Japanese cedar and Virginian cedar, they did not get infected by the brown-rot caused by the fungi Gloeophyllum trabeum. Moreover, the vapors and water emulsion of this oil have shown to inhibit the growth of notorious bacteria like Staphylococcus aureus (1). Mice studies have also demonstrated the larvicidali A kind of insecticide used to repel mosquito larvae before they can develop into adult mosquitoes. and parasiticidal activity of cedarwood oil.

Cedarwood oil contains α- and ß-cedrene, cedrol, thujopsene, widdrol, and other sesquiterpenesi A class of terpenes (chemical compounds) that have a wide range of pharmacological properties, such as antibacterial and anti-tumor. and hydrocarbons (1). The alcohol content of Texas cedarwood oil ranges from 35-48%, with a maximum of 20% cedrol. While Virginia cedarwood oil consists of about 80% α- and ß-cedrene, its cedrol content varies between 3 to 14%. Chinese cedarwood oil has a minimum of 8% cedrol (1).
