About (CRYPTOMERIA JAPONICA/CHAMAECYPARIS OBTUSA) STEM FERMENT EXTRACT

A spontaneous fermentation of Japanese cedar (Cryptomeria japonica) and hinoki cypress (Chamaecyparis obtusa) stems — two classic Japanese conifer species with potent lignan and terpenoid bioactives.

Detailed Analysis

(Cryptomeria japonica/Chamaecyparis obtusa) stem ferment extract uses spontaneous fermentation of the stems of Japanese cedar (sugi) and hinoki cypress in a traditional Japanese wood fermentation process. Cryptomeria japonica and Chamaecyparis obtusa both produce terpenoids (includinghinokinin and nootkatin) with documented antimicrobial and anti-inflammatory properties. Hinoki cypress extract is used in traditional Japanese bathing (hinoki-yu) and has a long safety record. The spontaneous fermentation process introduces some variability.
