À propos de cet ingrédient

Tochū-cha (eucommia leaf tea) and the bark are core herbal materials in TCM and Kampo. Modern functional positioning emphasises asperuloside and pinoresinol diglucoside, with FFC notifications in Japan referencing blood-pressure and triglyceride support. Domestic Japanese cultivation is concentrated in Nagano and Yamagata; the leaf-based supply for tea and supplements is largely Japan-domestic, while the bark draws on both Japanese and Chinese sourcing. Increasingly used in caffeine-free RTD beverage applications.
