The RootHerb® Index

Look up Thai and Japanese herbs by name, species, and culture

RootHerbs (rhizomes) that store their compounds beneath the soil, green herbs enjoyed for the aroma of their leaves and flowers, and the herbs from Japan— mugwort, white birch, kuromoji, shell ginger — used in saunas here. This index gathers the herbs of Thai traditional medicine and the herbal sauna “op samun phrai” alongside them, in a way that makes the differences clear. Tap a herb to read its species, its place in daily life, and the culture around it. “Herbs from Japan” here means the plants used in saunas in Japan, so the group includes species such as eucalyptus — native to Australia, but listed in the Japanese Pharmacopoeia (as eucalyptus oil) and in wide use here. Saunas in Japan that use these herbs are gathered in the Herbal Sauna Guide.
