Xanthoxylum Essential Oil
Xanthoxylum Essential Oil, is also known as Zanthoxylum, Tomar, and Timur Essential Oil.
Xanthoxylum Essential Oil is an intriguing yet much lesser known essential oil. Very little has been written about it.
The essential oil is typically steam distilled from dried fruits that resemble peppercorns. Steffen Arctander mentions that Xanthoxylum is known as "Chinese Wild Pepper" in the Far East. He describes the aroma of Xanthoxylum Essential Oil as "warm, woody, green-peppery and spicy" and that is it has an aroma that is reminiscent to cubeb and guaiacwood.

Xanthoxylum Essential Oil is abundant in linalol and limonene. It also contains about 6-10% of the ester methyl cinnamate which strongly contributes to the pleasantly fruity yet spicy aroma of the oil. The uses for Xanthoxylum Essential Oil are not well documented, but its composition of linalol and limonene may make the oil useful in anti-inflammatory, anti-microbial blends and blends intended to support emotional balance.
From a chemical standpoint, I find it interesting that Xanthoxylum Essential Oil shares some similarity to that of Neroli Essential Oil. For example, both oils share linalol compositions of approximately 35-40% and total monoterpenol compositions of about 45%. They also both contain about 15-20% limonene and share monoterpene compositions of about 35-40%. Their ester compositions are also somewhat similar. In no way do I mean to suggest that Xanthoxylum Essential Oil shares a smiliar aroma with Neroli Essential Oil (it doesn't), and the applications for each oil aren't the same. Neroli does tend to be comprised of more esters, particularly linalyl acetate. For example, I find Neroli Essential Oil to be much more calming. From personal experience, I find Xanthoxylum Essential Oil to be more of a balancing, adaptogenic oil. Xanthoxylum Essential Oil has been helping to improve my focus as needed while simultaneously providing a level of calm when needed. Your experience and results with the oil may be different. I recommend that you do more research into the oil and its composition to help you determine and verify the suitability of the essential oil for your particular needs.
In working aromatically with the oil, I find that it blends well with a wide array of essential oils especially those in the spice, citrus, wood and floral families.
