## What the research says

- Hinoki oil, and its constituent hinokitiol (β-thujaplicin), have been studied for antimicrobial and relaxation-related effects in the laboratory. These are in-vitro/preliminary findings, not clinical proof of benefit. — JEOR study on hinokitiol from Chamaecyparis obtusa (1998) (https://doi.org/10.1080/10412905.1998.9701018)

## Evidence

- Hinoki wood oil is a sesquiterpene-rich Japanese cypress oil (cadinols, cadinene, muurolol), the basis of its calming, wood-forest aroma. — PLOS ONE study (2015) (https://doi.org/10.1371/journal.pone.0143450)

## Frequently asked questions

### What is hinoki used for in Japan?

Hinoki (Japanese cypress) is prized in Japan for its wood — used in temples and baths — and its oil is valued for a clean, calming, forest-wood aroma central to 'forest bathing' (shinrin-yoku) traditions.

### What is hinokitiol?

Hinokitiol (β-thujaplicin) is a tropolone compound associated with hinoki and related cypresses, widely studied for antimicrobial activity. It's one reason hinoki wood resists decay.

### Is hinoki phototoxic?

No — hinoki is a wood oil with no phototoxic constituents, so there's no sun-exposure restriction. Dilute it for skin use as usual.
