Taiwan Hinoki Essential Oil
Chamaecyparis formosensis

Description
Taiwan Hinoki Essential Oil is also referred to as Hong Kuai Essential Oil, Taiwan Cypress Essential Oil and Formosan Cypress Essential Oil.

Taiwan Hinoki Essential Oil is steam distilled from the twigs and wood of Chamaecyparis formosensis, a revered coniferous tree that is indigenous to Taiwan. The tree and essential oil goes by several common names including Taiwan Hinoki, Hong Kuai, Taiwan Cypress and Formosan Cypress. Because of the naming similarity, it is often confused with Hinoki Essential Oil (Chamaecyparis obtusa). It's always important pay close attention to an essential oil's botanical name, and that holds especially true for this oil. (For more information, read the Importance of Using Botanical Names with Essential Oils.)
Taiwan Hinoki Essential Oil is especially abundant in sesquiterpinols. It is well suited for meditation and spiritual applications.
Aromatically, Taiwan Hinoki Essential Oil possesses a slightly sharp, woody aroma. I don't personally love the aroma of the essential oil on its own, but I do like it when used in moderation in blends. As you would expect, it blends very well with other wood essential oils and oils rich in sesquiterpenes/sesquiterpenols. Taiwan Hinoki Essential Oil also blends well with citrus and floral essential oils, particularly when it's used in low dilution.
Taiwan Hinoki is a conifer. For more information about conifer oils, read AromaWeb's Guide to Coniferous Essential Oils.
Sustainability Concerns
According to Wikipedia and several other sources, the Taiwan Cypress has been overharvested due to its overuse in building (and likely also due to its steam distillation for the production of essential oil). [Source: Wikipedia. Chamaecyparis formosensis.]
Because it is now an endangered tree, it is important to mindfully choose who you purchase this essential oil from and evalutate how they are sourcing their essential oil.
