Despite being marketed as cedarwood, Juniperus ashei is botanically a juniper — not a true Cedrus — and its oil profile reflects this distinction, with thujopsene (around 35%) and cedrol (around 27%) as the principal sesquiterpenes, alongside a-cedrene and β-cedrene.^[1] Compared with Atlas or Himalayan cedarwood, the aroma sits drier and more austere, with a faintly smoky, pencil-shaving quality that makes it a popular and cost-effective alternative in perfumery and aromatherapy. Cedrol and thujopsene, both abundant in J. ashei oil, have been shown to inhibit cytochrome P450 enzymes in human liver microsomes, relevant context for understanding potential herb-drug interactions with heavy topical use.^[2]
