RootHerb®
RootHerb® is an Eastern-born wellness concept that focuses on the “root” of herbs and spices grown underground and brings their components into daily life. A registered trademark advocated by the Japan Root Herb Association (JRHA), it organizes the roots long valued in traditional and folk medicine (ginger, turmeric, galangal, etc.) — in contrast to aroma-led green herbs.

Roots, slowly
gathered.Roots into daily life.
Japan Root Herb Association (JRHA) was founded to study, share, and preserve the traditional wisdom of herbal and spice roots — both academically and practically.
Ginger, turmeric, galangal, licorice — all of them roots that store their nourishment slowly beneath the soil, and all of them plants long used in the herbal traditions of Southeast Asia. Learning from the cultures on the ground in Thailand and beyond, we pass on where they come from and how they are used, in ways that suit modern life.
A root is a vessel that stores its nourishment slowly, beneath the soil.— JRHA Manifesto

What is RootHerb®
What is RootHerbMost of the herbs we see around us are green herbs with a fresh aroma — lemongrass, mint, and the like. The aromatic compounds of their leaves and flowers take the lead, and they have long been used to scent food and rooms.
In regions where traditional and folk medicine are rooted, by contrast, the "root" beneath the soil has long been the valued part — thought to be where the compounds concentrate.
This programme is about learning which part of which plant has been used, where, and how. RootHerb® is the name we put on that lineage of herbs used through the root, so it can be spoken of as one thing.
By knowing the components held in the root, we also promote the age-old idea of "ichibutsu-zentai" — that eating a food in its entirety brings good nutritional balance.
Within the roots that sleep beneath the soil, the rhythm of seasons and earth is held.
